Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 2836 was prepared by Technical Committee ISO/TC 130, Graphic technology.
This third edition cancels and replaces the second edition (ISO 2836:1999). It also incorporated the
requirements of, and cancels, ISO 2837:1996 Graphic technology — Prints and printing inks — Assessment
of resistance to solvents and ISO 11628:1995 Graphic technology — Prints and printing inks — Determination
of resistance of prints to acids.

INTERNATIONAL STANDARD ISO 2836:2004(E)

Graphic technology — Prints and printing inks — Assessment
of resistance to various agents
1 Scope
This International Standard specifies methods of assessing the resistance of printed materials to liquid and
solid agents, solvents, varnishes, and acids.
It applies to printing on all substrates by all of the traditional printing processes and digital imaging processes
such as ink-jet, electrophotography, etc. using marking materials appropriate to the printing process used.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 2834:1999, Graphic technology — Test print preparation for offset and letterpress inks
ISO 105-A03:1993, Textiles — Tests for colour fastness — Part A03: Grey scale for assessing staining
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
agent
liquid or solid to which a sample of printed material is exposed for the purpose of determining the resistance
characteristics of that printed sample
3.2
resistance
ability of a printed material to withstand exposure to a specified agent as determined by the tests defined in
this International Standard

4 Principle
4.1 Liquid and solid agents
A test piece cut from the print is brought into contact with the agent used. Assessment is made of any
changes in the print and in the receptor surface which has been in contact with the print.
4.2 Solvents and varnishes
A test piece cut from the print is immersed in the prescribed solvent or test varnish for a given time. The colour
change of the solvent or varnish and the discoloration and any change of the test piece are noted and
reported.
4.3 Acids
A test piece cut from the print is pressed between two sheets of filter paper previously wetted with a solution
of the relevant acid. An assessment is made of any change to the print and any bleeding of the colour onto the
filter paper.
NOTE 1 The type and concentration of the acid and the duration of exposure are not standardized, but should be
chosen according to the intended application of the print. Table 1 gives a list of commonly used types, concentrations and
exposure durations.
NOTE 2 The test piece includes both printing ink and substrate, because resistance
