Graphic technology — Colour and transparency of printing ink sets for seven-colour offset printing

Scope

This document defines the colour and transparency of lithographic printing inks orange (O), green (G) and violet (V) for seven-colour offset printing. Different sets of inks conforming to this standard will produce a similar colour when printed on the same substrate at the appropriate film thickness. This enables colour separations to be based on known colour references and simplifies the task of consistently printing the same images in multiple printing sites.
