What is ISO/TS 21139‑1 about?
ISO/TS 21139‑1 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 ISO/TS 21139‑1 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 stationery 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 displayed in consumer home environments and prints exhibited or stored in the museum context, are outside the scope of ISO/TS 21139‑1.
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.
Who is ISO/TS 21139‑1 for?
ISO/TS 211391 on permanence and durability of commercial prints is useful for:
- Printing equipment manufacturers and suppliers
- Printing production personnel
- Printing professionals, including auditors, consultants, etc.
- Print buyers and purchasers
Why should you use ISO/TS 21139‑1?
ISO/TS 21139 (all parts) defines use profiles and test methods for permanence and durability testing of printed matter for use in the context of commercial applications, which resemble a wide range of product and usage classes (see e.g., ISO/TR 19300). Product classes included are commercial production prints (flyers, brochures), transactional and stationery prints, signage, newspapers and periodical prints, book printing as well as packaging printing.
For permanence testing, either single or combined stress factors are applied in accelerated laboratory tests that aim to simulate the degradation observed in-field use. ISO/TS 21139 (all parts) defines test methods that are appropriate to simulate exposure in use profiles of printed matter in a variety of uses.
The test methods and guiding principle described in ISO/TS 21139‑1apply to both, analog 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.
