IEC 62899-203-2:2025 specifies a method to measure the values of effective charge carrier mobility in printed semiconductive layers using space charge limited current (SCLC) mobility technique. The method described is intended to be used as a benchmark test to allow reproducible measurements at a given temperature of the apparent charge carrier mobility for comparison with devices that use different materials, material formulations and fabrication processes for a planar configuration. This document specifies the sample and equipment requirements, and describes the measurement technique, the data analysis procedure and the reporting protocol.
This document is suitable to test unipolar devices (i.e. hole-only or electron-only), where charge injection is efficient and where series resistance does not dominate the current-voltage curve. Therefore, it cannot be used for testing high-electron mobility devices where electron injection can be problematic, for testing highly doped materials where space charge limited current does not exist, or to evaluate mobility in applications that require lateral charge transport, such as in transistors.

SIGNIFICANCE AND USE
5.1 This test method has found acceptance in the lithographic ink industry in predicting rheological behavior of a vehicle under press conditions caused by extrusion, shear-thinning rollers and dot gain recovery.
5.2 This test method is restricted within the torque limitations and strain resolution of the rheometer used.
5.3 Results may not be reproducible if the vehicle is not homogenous.
SCOPE
1.1 This test method covers the procedure for determining the viscoelastic properties of printing ink vehicles by measuring the G', G”, and tan delta using a controlled strain cone and plate oscillatory rheometer.
1.2 This test method provides the flexibility of using several different types of rheometers to determine viscoelastic properties in ink vehicles.

SIGNIFICANCE AND USE
4.1 This test method is the procedure of choice for determining volatile content of sheet-fed and coldset web offset inks. This information is useful to the ink manufacturer and user and to environmental interests as part of the determination of the mass of volatile organic compounds emitted from the ink.
Note 3: Since these inks do not contain water or any materials currently classified by US EPA as negligibly photochemically reactive (exempt solvents), volatile organic compound content is the same as volatile content. The volatile organic compounds in these inks are high boiling hydrocarbon oils which are, according to US EPA guidelines, 95 % retained in the printed substrate or oxidized into the ink film. Therefore, the mass of volatile organic compound emitted from the ink would be calculated as only 5 % of the volatile organic compound content of the ink as derived from the results of this test method.
SCOPE
1.1 This test method describes a procedure for determination of the weight percent volatile content of sheet-fed and coldset web offset printing inks. Test specimens are heated at 110 °C ± 1 °C for 60 min.
Note 1: Coldset web offset printing is often (also) referred to as non-heatset web offset printing.
1.2 This test method is also applicable to sheet-fed and coldset web offset printing ink vehicles.
Note 2: Vehicle is the liquid portion of the printing ink. Any substance that is dissolved in the liquid portion of the ink is a part of the vehicle.
1.3 This test method is not applicable to ultra-violet (UV) or electron beam cured materials, which must be cured by exposure to UV light or an electron beam as part of the test for volatile content.
1.4 This test method is based on Test Method D2369, in which the allowable ranges are ±0.1 g for specimen weight and ±5 °C for oven temperature. Interlaboratory studies have shown that specimen weight and oven temperature must both be more tightly controlled in order to improve the precision of test results for sheet-fed and coldset web-offset inks. Such inks typically contain a wide range of high-boiling hydrocarbons and often have a volatile content below 25 %.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement see 7.5.1
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 The yield stress of a material is a measure of the amount of force required to initiate movement of that material in a pipe, through a pump, or from nozzle. The yield stress also characterizes the ability of the material to maintain particles in suspension. Along with viscosity measurements, yield stress measurements have been useful in establishing root causes of flow problems such as excessive orange peel and sagging and in explaining resistance to such problems. After a coating has been applied, flow and leveling tends to be inversely related to yield stress and sag resistance tends to be directly related to yield stress. The ability of an automotive basecoat to keep aluminum and/or mica flakes oriented has been related to yield stress (direct relationship).
SCOPE
1.1 These test methods cover three approaches for determining yield stress values of paints, inks and related liquid materials using rotational viscometers. The first method uses a rotational viscometer with coaxial cylinder, cone/plate, or plate/plate geometry. The second method uses a rheometer operating in controlled stress mode with similar geometries. The third method uses a viscometer with a vane spindle.
1.2 A non-rotational technique, the falling needle viscometer (FNV), also can be used to measure yield stress values in paints, inks and related materials. See Test Methods D5478, Test Method D, Yield Stress Determination for details.

SIGNIFICANCE AND USE
5.1 The viscosity of paint, inks and many related liquid materials is dependent on temperature. It is useful to know the extent of this dependence. One use of such information is to prepare a viscosity-temperature table or curve. Then, if ambient conditions do not allow the measurement of viscosity at the exact temperature stated in a specification or regulation, the viscosity measured at ambient temperature can be used to determine the viscosity at the temperature of interest through the use of the previously prepared table or curve. Viscosity measurements that cover a range of shear rates as well as temperatures could include shear rates associated with paint application or allow extrapolation to such shear rates. This information would enable a producer or user to estimate the effect on application of heating the paint.
SCOPE
1.1 These test methods cover the use of rotational viscometers to determine the dependence of apparent viscosity of paints, inks and related liquid materials on temperature. The first method uses a standard rotational viscometer with concentric cylinder geometry running at a fixed rotational speed as the temperature is increased or decreased. The second method uses a rotational viscometer with cone and plate geometry running at a fixed rotational speed as the temperature is increased or decreased. The third method uses concentric cylinder or cone/plate geometry operated with a shear rate ramp at several discrete temperatures.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
5.1 These practices provide means of preparing small quantities of resin solution (in some procedures in an inert gas atmosphere using uniform, controlled heating).
5.2 This practice provides quick ways to prepare a resin solution for quality control testing during the manufacture of resin solutions and vehicles. Samples can usually be prepared in approximately 30 to 45 minutes or less.
5.3 These practices can be used to prepare commonly specified ink test solutions such as 33.3 % resin in alkali refined linseed oil, and 50 % resin in heat-set ink solvent (that is, C12 to C16 hydrocarbon petroleum distillate with initial boiling point (IBP) about 470°F).
SCOPE
1.1 These practices describe laboratory procedures for preparing an oil-based ink resin solution in a high-boiling solvent using four pieces of lab equipment:
(1) A hot oil bath (Sections 4 to 11),
(2) A stirrer/hot plate (Sections 12 to 16),
(3) An industrial blender (Sections 17 to 22), and
(4) A hot air gun (Sections 23 to 27).
ASTM Subcommittee D01.37 recommends using the hot oil bath procedure (Practice D5597) where possible.
1.2 These practices use laboratory equipment generally available in a normal, well-equipped laboratory.
1.3 One or several of these practices allows for rapid resin solution preparation (under 30 min, typical), can regulate the maximum temperature, can be done under an inert atmosphere, and can prevent the random solvent loss during preparation.
1.4 These procedures are for use with ink resins intended mainly for oil-based offset and letterpress inks. The type of resins are typically, but not limited to C9 aromatic hydrocarbon resins, modified dicyclopentadiene resins, rosin pentaerythritol or glycerine esters, phenolic modified rosin esters, maleic anhydride modified rosin esters, and naturally occurring resins such as gilsonite.
1.5 The typical high boiling solvents to be used include C12 to C16 petroleum distillates, 2,2,4 trimethyl 1,3-pentanediol di-isobutyrate,2 alkali refined linseed oil, tridecyl alcohol, or combinations of the above.
1.6 To avoid fire or injury, or both, to the operator, these practices should not be used with low flash point solvents such as toluene or xylene. The minimum flash point of the solvents used should be 60°C (140°F) as determined by Test Method D56. (Warning—Users of this practice should be aware that the flash point of many solvents used for this test (as defined in Test Methods D56 and D1310) is exceeded in the heating cycle of this test method. Take safety precautions since there is the potential for vapor ignition. Do the methods outlined in a shielded exhaust hood, where there is access to a fire extinguisher if needed.)

SIGNIFICANCE AND USE
5.1 It is generally recognized that the best method for evaluating printing properties of ink-substrate combinations is by actual printing. this practice provides a convenient method for preparing repeatable laboratory prints at realistic conditions of printing speed, printing pressure and ink film thickness.
5.2 This practice is useful for quality control, specification acceptance between producer and user, product development and research. Printed samples have found widespread applications for color matching, gloss-ink holdout and other appearance properties, permanency, abrasion, drying time and many other tests of interest to the printing ink, paper and allied industries.
SCOPE
1.1 This practice describes the procedure for preparing laboratory prints of paste printing inks using a motor-driven printability tester.
1.2 This practice covers printability testers of four different designs, referred to as Tester A, B, C, and D. These testers feature “push-button” control of printing speed and pressure and facilitate measurement of exact ink film thickness.
1.3 This practice is intended primarily for lithographic and letterpress inks that dry by oxidation or penetration. With appropriate drying or curing equipment, it is also applicable to other systems such as heat-set or energy curable.
1.4 This practice is applicable to the preparation of single-color solid-area prints by dry offset (also know as letterset) or by letterpress on any flat surface including paper, paperboard, plastic film, textiles, and metal.
1.5 The values stated in SI units are to be regarded as the standard. The only other unit of measurement used is fpm.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
5.1 Oversize particles in a printing ink may damage a printing plate, plug a cell, clog a nozzle and adversely affect the appearance of printed ink films. Fineness of grind measurements are useful for deciding when to stop the dispersion process and for determining if the test material meets specifications as agreed upon between the supplier and the customer.
SCOPE
1.1 This test method describes the procedure for determining the fineness of grind of printing inks using a NPIRI Grindometer. It evaluates the size of the largest particles in a finished dispersion but not average particle size or concentration of sizes.
1.2 This test method covers both manual and automatic drawdowns using an A1 scraper.
1.3 This test method is applicable to any dispersion that is fine enough to fall within the 0 to 25 μm range of the specified grind gauge. With a minor variation in procedure, it is applicable to both paste (nonvolatile) and liquid (volatile) inks.
Note 1: The 0 to 25 μm gauge specified in this test method is similar in principle to the 0 to 100 μm Hegman gauge described in Test Method D1210 and the various gauges described in ISO 1524:2000. Sieve analysis for concentration of particles above 45 μm is covered in Test Method D2067.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
3.1 When formulating printing inks and overprint varnishes that dry primarily by oxidation it is important to know the stay open time so that premature drying does not occur on the printing press rollers and other components.
3.2 The applied ink or OPV film used for testing is thicker than the film printed on the substrate and nominally represents the film on the printing press rollers.
SCOPE
1.1 This test method covers a manual procedure for determining the stay open time of oxidative drying printing inks and overprint varnishes by a finger transfer method. Open is defined as a wet ink/varnish film.
1.2 The amount of time required to reach the endpoint is recorded in hours.
1.3 Typical inks and overprint varnishes that dry by oxidation are oil based sheetfed offset, letterpress, and screen inks.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
5.1 Tinting strength is an essential property of printing ink dispersions. Although test results on wet drawdowns and tints do not guarantee equivalency of dry printed ink films, they provide useful parameters for quality assurance of established formulations, gaging relative degree of dispersion, and estimating the color value of colorants from different batches, sources, or grades.
SCOPE
1.1 These test methods cover procedures for determining the relative tinting strength of paste-type printing ink dispersions by visual or instrumental evaluation of tints prepared by manual or automated mixing.
1.2 These test methods are applicable to paste-type printing inks, flushed pigments, and other pigment dispersions that are essentially nonvolatile under ordinary room conditions and for which there is a wet reference standard of the same pigmentation and consistency. With proper choice of tinting base, they are applicable to dispersions of any color, including black and white.
Note 1: The instrumental procedures for tinting strength are similar in principle to those described in Test Methods D387, D2745, D4838, and D6531.

4.2 In order to obtain accurate results for heatset systems within the specified 3-h heating time, the specimen film thickness must be less than 100 g/m2, and the oven must have forced ventilation. Thickness of the specimen film is less critical for liquid ink systems.
SCOPE
1.1 These test methods cover the determination of weight content of nonvolatile matter in two types of printing inks.
1.2 Test Method A is applicable to heatset-type printing inks and resin solutions; solvents in such systems typically have initial boiling points in the range from 240 to 275°C (470 to 535°F) and vapor pressures less than 0.2 mm Hg.
1.3 Test Method B is applicable to liquid-type printing inks and vehicles based on aqueous or organic solvents that evaporate readily at ordinary room temperatures.
Note 1: Test Method A (for heatset systems) specifies a specimen film thickness that is much thinner than those produced by related test methods; one exception is Test Method B in Test Methods D1259, which is recommended as a referee test.
Note 2: Test Method B (for liquid ink systems) is similar to Test Method D2369 except that a solvent is not required for spreading the test specimen.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
3.1 The lithographic printing process requires that some dampening solution be emulsified into the ink. These test methods provide a rapid means for determining water pickup under laboratory conditions. Test results may be useful for specification acceptance between the supplier and the customer.
3.2 In order that results be comparable, the tests must be run at the same temperature and with the same type and quantity of liquid added prior to mixing.
3.3 The emulsions obtained in these test methods are of larger particle size than those typically produced in printing nips. Because of these and other variables in the printing process, water pickup results do not by themselves predict lithographic printing performance.
SCOPE
1.1 These test methods cover two procedures for determining the amount of water picked up by lithographic printing inks in a laboratory mixer.
1.2 Test Method A covers single-point water pickup; Test Method B covers the rate of water pickup. Both test methods are applicable to any printing ink and vehicle intended for the lithographic printing process.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

SIGNIFICANCE AND USE
4.1 Laboratory proofing of inks is necessary to establish a reproducible prediction of print appearance and performance properties, most of which are highly sensitive to ink film thickness. The apparatus described in this practice has found wide use for routine control proofing because it provides an economical method for producing reasonably large prints at film thicknesses comparable to those obtained on production presses.
FIG. 1 Schematic Diagram of Printing Gages (not drawn to scale)
4.2 A unique advantage of printing gages is that, depending on the design selected, prints can be produced at a range of tapered film thicknesses or at several levels of uniform thicknesses in a single proofing. Because of the built-in film thickness control, ink metering is not necessary. Relatively small quantities of test samples are used, and less than two minutes are required to ink a gage, pull a letterpress print, and clean up. In addition, problems due to ink distribution systems are eliminated, two inks may be proofed at the same time, and multi-color printing is possible.
4.3 This practice does not duplicate the dynamics of a high speed press, nevertheless, it is useful for quality control and for specification acceptance between the producer and the user.
SCOPE
1.1 This practice covers the procedure for preparing laboratory prints of paste inks using a printing gage in conjunction with a flat-bed proof press.
1.2 This practice is applicable to the preparation of solid-area prints by direct letterpress or by dry offset on a flat substrate such as paper, paperboard, or metal.
1.3 This practice is applicable primarily to lithographic and letterpress inks that dry by oxidation or penetration. With the addition of appropriate drying or curing equipment, it is also applicable to other paste ink systems such as heat-set or energy-curable.
1.4 The instructions in this practice are intended to minimize the within-print and among-operator variability inherent in hand operations.
1.5 This practice features built-in ink film thickness control. It does not measure the film thickness transferred to the print; however, film thickness equivalence may be evaluated by visual or instrumental comparisons of optical density.
1.6 Values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

SIGNIFICANCE AND USE
5.1 The setting speed of heatset printing inks is important because it influences the efficiency of the drying process. This test method provides a means for comparing the setting of a heatset ink directly against a standard at the same conditions of temperature and exposure time. While the method does not determine the setting speed of an ink on a production press, it is useful for specification acceptance between the supplier and the customer.
5.2 The setting speed of a printing ink depends on a number of variables such as the substrate on which it is printed, the film thickness on the print, the temperature of the forced air, the rate of air flow, and the time that the print is subjected to heat. For these reasons, it is important to conduct the tests under conditions that are controlled and as realistic as practical.
SCOPE
1.1 This test method describes the procedure for determining the relative setting speed of heatset inks using a tester consisting of a forced hot air oven and print delivery system.
1.2 This test method is applicable to printing inks intended to be dried by the application of heat and for which a suitable reference standard is available.
1.3 Although heatset inks are normally printed by the offset process, this test method specifies the direct letterpress mode because the higher ink film thicknesses obtained tend to amplify subtle differences in ink setting speed. Prints are prepared by a flatbed printing apparatus using a constant depth printing gage.
1.4 This tester reads temperature and belt speed in nonmetric terms; therefore, instrument settings in this test method are stated first in U.S. Customary Units (inch pound units of measurements). The values given in parentheses are for information only.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
4.1 Coarse particles in printing inks reduce the efficiency of the dispersion process, requiring not only extra milling passes, but also frequent changes in pump filters. In printing processes, they may cause excessive wear to metal plates, piling or localized retention of ink on blankets and plates, and water balance problems. Coarse particles also reduce color strength and the gloss of printed matter.
4.2 This test method is suitable for quality control. The precision may be improved by the use of a specimen size larger than that prescribed.
4.3 Test results are sensitive to the type of washout solvent used. Strong solvents are to be avoided because they may dissolve large particles of resin in the ink vehicle.
SCOPE
1.1 This test method covers the determination of the weight concentration of coarse particles in printing ink dispersions by sieve retention.
1.2 This test method is applicable to printing inks, flushed pigments, and other pigment dispersions that contain particles larger than 45 μm. With proper choice of solvent, it is applicable both to paste and liquid inks.
Note 1: This test method is similar in principle to Test Methods D185. For particles under 25 μm, see Test Method D1316.

SIGNIFICANCE AND USE
4.1 This practice provides a means of preparing resin solutions by the “cold cut” method, modeling high-shear production dispersion techniques.
SCOPE
1.1 These practices describe laboratory procedures for preparing a solvent or water based ink resin solution in low boiling solvent or alkaline water using two types of lab equipment; (1) an industrial blender (Sections 3 – 7), and (2) a laboratory roller mill (Sections 8 – 12).
Note 1: ASTM Subcommittee D01.37 recommends using the industrial blender where possible.
1.2 These practices use laboratory equipment generally available in a normal, well-equipped laboratory.
1.3 These procedures are for use with ink resins intended mainly for liquid (for example, flexographic and rotogravure) inks. The type of resins is typically, but not limited to, acrylic and styrene/acrylic copolymers, polyamides, polyesters, polyvinylbutyral, and maleated/fumarated rosin esters.
1.4 The typical low boiling solvents to be used include ethanol, isopropanol, n-propanol, ethyl acetate, isopropyl acetate, and n-propyl acetate. For water based ink resin solutions, water is used in combination with ammonium hydroxide or amines such as dimethylethanolamine, monoethanolamine, and triethylamine.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

SIGNIFICANCE AND USE
4.1 Many types of printed matter, notably container labels, packaging materials, magazine and book covers, must be resistant to liquid materials that may contact them advertently or inadvertently. This practice permits an assessment of resistance of printed matter to several types of liquids.
4.2 The requirement that a reference print be run at the same time as the test print minimizes effects of atmospheric conditions (humidity and temperature) and other variations which may develop.
4.3 This practice can be used to determine whether new formulations are suitable for the end-use purpose and for specification acceptance between producer and user.
SCOPE
1.1 This practice covers the evaluation of the relative resistance of printed matter to liquid chemicals, as evidenced by lack of discoloration, bleeding, or loss of gloss.
1.2 This practice utilizes a sandwich procedure similar in principle to ISO/TC 130 N 589. Spotting or immersion procedures are covered in Test Methods D1308, D1647, and D2248.
1.3 This practice is applicable to prints on any flat substrate including paper, paperboard, metallic foil, metal plate, and plastic films, and produced by any printing process including letterpress, offset lithography, flexography, gravure, silk screen, and non-impact.

SIGNIFICANCE AND USE
5.1 Inadequate setting or drying of sheetfed inks, or both, can cause blocking of stacked prints with subsequent loss of product. “Setting” of an ink refers to the rapid rise in viscosity of the printed ink film, sometimes accompanied by surface drying, that prevents transference of the undried ink film to adjacent surfaces under light pressure. “Setting” is a property of the ink-substrate combination. Inadequate drying may be due to several factors, but the primary causes are: (1) omission of metallic driers from the ink, improper ink formulation (2) unusual ink-substrate interactions, and (3) use of a fountain solution that is too acidic. If the test prints are made on a standard laboratory proof press, where there is no application of fountain solution, then only the first three possible causes can be evaluated. If the prints have been made on a commercial production printing press or some other acceptable means of introducing the fountain solution into the ink agreed upon, then the effect of fountain solution can be determined. It will often be necessary to run several tests to isolate the specific cause of a drying problem.
5.2 This test method is suitable for most combinations of oxidative drying inks and substrates. Because this test method relies on a visual assessment of the extent of drying, very light colors and clear varnishes may present difficulties in quantifying the extent of drying. In such cases, the supplier and the customer should agree upon an alternative method of assessing the drying properties of the ink.
SCOPE
1.1 This test method covers the procedure for determining the drying time of oxidative-drying printing inks (also referred to as “sheetfed inks”) by squalene resistance of printed ink films.
1.2 This test method is applicable to all paste inks that dry primarily by oxidation regardless of the substrate on which they are printed. With appropriate changes in the test fluid, it may also be used with paste inks that dry by other mechanisms, such as heatset or ultraviolet light.
1.3 This test method utilizes a modified rub tester and is intended to serve as a “referee” procedure when laboratories, using less rigorous test procedures (see Appendix X1), cannot agree on their results.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

SIGNIFICANCE AND USE
5.1 Ink mileage on a production press is of economic importance of the user of printing inks, the lower the mileage figure, the less ink is required to produce a job. This test method provides a procedure by which news inks can be assessed for mileage or newsprint stocks for ink receptivity in the laboratory.
5.2 Because of the many variables that exist among laboratory and production presses, this test method is apt to yield more meaningful information when results are expressed on a relative rather than an absolute basis.
SCOPE
1.1 This test method covers the laboratory procedure for determining the relative mileage of news inks on newsprint. The test method utilizes a proofing press, analytical balance and a reflection densitometer.
1.2 This test method is intended for black oil-based news inks that dry by penetration (that is, letterpress or web offset) and for which a suitable reference standard is available. With appropriate optical instrumentation, it is also applicable to colored news inks.
1.3 This test method may also be used to determine the relative ink receptivity of test newsprints versus a reference standard.

SIGNIFICANCE AND USE
5.1 Tinting strength is an essential property of printing ink dispersions. Although results on bulk tints do not guarantee equivalency of dry printed films, they provide useful parameters for quality control of production batches of bases and finished inks. Test results may also be used for color matching purposes.
SCOPE
1.1 This test method covers the procedure for determining the relative tinting strength of waterbased ink systems using a computer-aided spectrophotometer.
1.2 This test method is applicable to waterbased printing inks and bases to be used primarily in flexographic and gravure printing applications.
1.3 This test method applies only to single, non-fluorescent pigmented colors and black ink systems for which there is a reference standard containing a pigment of the identical color index name and number.
1.4 The procedure in this test method specifies placing tinted samples in a cuvette for spectrophotometric measurements. The use of thick wet drawdowns as in Test Methods D2066 are inappropriate due to severe floating problems with aqueous systems.

SIGNIFICANCE AND USE
5.1 Apparent viscosity at the relatively high shear rate of 2500 s−1 does not completely define the rheological properties of printing inks but is useful in the practical control of ink viscosity during production and the specification acceptance between supplier and purchaser.
5.2 The slope of the power law plot is the preferred measure of non-Newtonianism. The yield value, which is obtained by extrapolation of high-shear measurements to a shear rate approaching zero, does not conform to the definition of the true yield stress (see 3.1.7). The yield value and other low shear parameters are also subject to a high degree of variability (see the precision table in Section 16).
SCOPE
1.1 This test method covers the procedure for determining the falling-rod viscosity and degree of non-Newtonian behavior of printing inks, vehicles, and similar liquids that are essentially nonvolatile and unreactive under ordinary room conditions.
1.2 For printing inks, which are typically non-Newtonian, this test method is applicable in the apparent viscosity range from about 10 to 300 P at a shear rate of 2500 s−1. For Newtonian liquids, the applicable viscosity range is about 10 to 1000 P (1 P = 0.1 Pa·s).
1.3 This test method uses a falling-rod viscometer in which shear conditions are altered by manually adding weight to the rod. A fully automatic instrument is described in Test Method D6606.
1.4 This test method, as does Test Method D6606, bases calculations on the power law model of viscosity. ISO 12644 covers not only the power law but also the Casson and Bingham models.

SIGNIFICANCE AND USE
3.1 Poor adhesion of ink or coating to the base substrate can impact the readability of printed materials, affect the functionality of coated materials, or create a source of contamination. This practice provides a means for evaluating the adhesion of ink or coating to a flexible packaging material.
3.2 For purposes of resolving inter-laboratory disagreements, test methods developed from this practice may be improved by defining and controlling the pressure and method of tape application, (for example, using weighted roller), and the speed and angle of tape removal.
3.3 This practice does not address acceptability criteria. These need to be jointly determined by the user and producer of the product.
SCOPE
1.1 This practice describes a means of evaluating ink or coating adhesion to flexible packaging materials. This practice is intended for use on flexible packaging materials whose surfaces are not damaged by the application and removal of tape.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

SIGNIFICANCE AND USE
3.1 Packaging materials may be exposed to chemicals such as water, alcohol, acid, etc. during their life cycle. If it is anticipated that the packaging material will be exposed to a chemical, it is important that the ink or coating, or both, not degrade, soften, or dissolve as a result of that contact.
3.2 The testing included in this practice is applicable to surface printed and coated materials designed to be resistant to a specific chemical.
3.3 The chemicals to be tested should be compatible with (that is, not damage or degrade) the substrate being printed or coated, or both.
3.4 There are four separate methods detailed in this practice. The methods represent increasing degrees of severity from Method A to Method D. Selection of method should be based on the type of exposure anticipated. For example, the pouring method (Method A) is typically used where incidental exposure is anticipated, such as a spill or splash of chemical on the material surface. Method B or C is typically used when chemical resistance is desired depending on the level of exposure (B) and abrasion (C) anticipated. Method D would represent continual contact between the chemical and material and would need to be chemical-proof, (for example, if the package were to be submerged in the chemical and exposed to abrasion over a period of time.)
3.5 This practice does not address acceptability criteria. These need to be jointly determined by the user and producer of the product, based on the type of exposure that is anticipated.
SCOPE
1.1 This practice describes the procedure for evaluating the ability of an ink, overprint varnish or coating to withstand chemical exposure. Typical chemicals, which may come in contact with the package, include water, alcohol, acid, etc. The specific chemical and method of choice as well as determination of measurement outcome are left to users to agree upon in joint discussion. Suggestions for ways to measure and collect information are offered in the various methods listed in this practice.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
