Graphic technology－Prints and printing inks－Assessment of resistance to solvents

This document establishes the standardized methodology for evaluating the solvent resistance of printing inks applied to printed products. It outlines specific test procedures designed to assess how well ink coatings withstand exposure to various solvents under controlled conditions. The approach covers preparation of test specimens, application of solvents, and observation criteria to determine the degree of ink degradation or dissolution. By providing a uniform framework, it enables consistent comparison of ink performance across different printing materials and substrates. The procedure is particularly relevant for quality control in printing industries where durability against chemical agents is critical. It details the necessary equipment, environmental conditions, and interpretation of results to ensure reproducibility. This technical specification supports manufacturers and testers in verifying the suitability of inks for specific applications where solvent exposure may occur during handling, cleaning, or end-use scenarios. Through its structured format, it facilitates communication of technical requirements between suppliers and clients within the printing supply chain.
