Since the year 2000 the viewing standards for the graphic arts industries have been redefined, in order to eliminate discrepancies in color analysis of the printed copy. ISO 3664 : 2000 called for tighter standards of color viewing booths. Additionally the new certification for process standardization in offset printing Ð ISO 12647-2 Ð has been established enabling individual printing companies to objectively document the quality of its printing production, satisfying the most demanding of customers.
