The ISO 2846-2-2017 standard specifies the Color and transparency requirements for inks for four-color cold-set planographic printing. The standard describes how to measure the Color and transparency of inks on a printability tester under specified conditions and ensure that inks produce a consistent Color on the reference substrate. This part of the standard allows Printing inks obtained from different sources to produce a consistent Color effect in printing, subject to Colorimetric and transparency requirements, suitable for cold-set offset printing processes.
