The ISO 2834-2: 2022 standard describes methods for preparing samples for liquid Printing inks (including water-based, solvent-based and radiation-curing inks) in laboratories. The standard applies to flexographic printing and gravure printing and specifies methods for preparing test prints to ensure uniform distribution of inks and repeatability. This standard allows reflection-based measurement and light fastness testing, as well as evaluating inks' resistance to mechanical and chemical erosion of substrates. The standard provides detailed guidance on the operating setup and test equipment for Liquid ink printing to help ensure the accuracy of test results.
