ISO/TC 42/JWG 27 - Joint ISO/TC 42 - JTC1/SC 28 - ISO/TC 130 WG: Image permanence & durability test methods and specifications for digital prints in commercial applications

This document specifies test methods to determine the rub resistance of analogue and digital prints. This includes photographic as well as graphic and office prints on all substrates. ISO 18947-1 provides information and general guidance relevant to the selection and operation of abrasion test methods and also describes general performance requirements for abrasion test devices used.

This document defines use profiles for commercial prints in terms of typical environmental stress factors and any mechanical and chemical stress factors to be considered additionally in their application. Methods and principles defined in this document apply to the various product classes of "commercial prints" that, following the terminology of ISO/TS 19300, include commercial production prints (flyers, brochures), transactional and stationary prints, signage, newspapers and periodical prints, book printing as well as packaging printing. These commercial prints often contain combinations of text, pictorial images and/or artwork. Prints for non-commercial use, including prints use and display in consumer home environments and prints exhibited or stored in museum context, are outside the scope of this document. For each use profile a set of suitable accelerated test methods for the leading environmental and/or mechanical or chemical stress factors is defined for representative testing. Guidance is given for translation of test results into suitable image permanence performance claims considering the variability of actual use in comparison to reference use profiles. The test methods and guiding principle described in this document apply to both, analogue and digitally printed matter, and the corresponding test targets from the ISO 12647 series are used. Methods and principles apply to both colour and monochrome prints.

This document describes the test method for light stability and ozone stability for commercial prints, which are displayed in indoor bright places in or near to windows, especially in display windows with air conditioning. This document also provides guidelines for data analysis. This document is applicable to the various product classes of "commercial prints" that, following the terminology of ISO/TR 19300, include commercial production prints (flyers, brochures), transactional and stationary prints, signage, newspapers and periodical prints, book printing as well as packaging printing. These commercial prints often contain combinations of text, pictorial images and/or artwork. Prints for non-commercial use, including prints used and displayed in consumer home environments and prints exhibited or stored in museum context, are outside the scope of this document. This document is applicable to both analogue and digitally printed matter. Methods and principles apply to both, colour and monochrome prints.
