ISO/FDIS 2846, Graphic technology --Colour and transparency of ink sets for four-colour-printing

摘要

A working group consisting of TC 130/WG 4 and WG 3 experts for materials and process control examined the colorimetric properties of coldset web-offset inks from around the world and found that a single set of colour coordinates could adequately represent these, within reasonable tolerances. Part 2 of ISO 2846 is the result of that activity It will enable printers to obtain a reasonable consistency between one another and thereby ensure that separations and digital images supplied to them can be used to best advantage.Part 2 of ISO 2846 will allow printers to obtain sets of process inks from various sources which will produce a similar colour when printed on the reference substrate at the appropriate film thickness. This will allow colour separations for coldset web-offset printing to be based on known colour standards. The colorimetric characteristics specified in this part of ISO 2846 only be obtained when the inks are printed on the reference substrate. However, similarity of two inks on the reference substrate will ensure similarity on another substrate.
