These reagents will come into contact with the printed materials during the subsequent processes such as varnishing. or accidental contact with printed matter through interaction with certain vapors, liquids or solids (e.g. spillage of packaging contents onto printed matter). These types of agents can cause visual changes in printed products. These changes are due to the colorants used in the ink or the substrate itself being sensitive to specific Reagent intolerance. All methods in this document are intended to allow the rational selection of raw materials for printing inks and substrates, and for testing of prints for use with The purpose of all these methods is to avoid visual changes in the print caused by solvents. Printing technology Printed materials and printing inks Determination of resistance to various reagents1 ScopeThis document describes the method for determining the resistance of printed materials to liquid and solid reagents, solvents, varnishes and acids. This document is suitable for all kinds of traditional printing (offset, silk screen, gravure, flexo, etc.), as well as digital printing (inkjet, electrostatic photography, etc.). This document does not cover food safety and consumer protection aspects of food contact materials. 2 Normative references The contents of the following documents constitute the essential clauses of this document through normative references in this document.
