Introduction
The demand for the publication gravure printing process to become more consistent and predictable has required a means of standardizing the product to ensure the easy flow of business between the various parties involved in its production. An essential component in this process is the colorimetric characteristics of the ink set.
To produce a set of standard four-colour process inks suitable for gravure printing it is necessary to specify a number of parameters. It is the purpose of this part of ISO 2846 to describe those parameters which affect the colorimetric characteristics in such a manner that a standard set of inks can be supplied by any ink manufacturer to any printer who can then supply prints to a print buyer with confidence in the colour of the work produced.
This part of ISO 2846 will allow publication gravure printers to obtain different sets of inks that will produce a similar colour when printed on the same substrate. In addition, it will allow colour separations for gravure printing to be based on known colour standards. The colorimetric characteristics specified may only be obtained when the inks are printed on the reference substrate. However, two inks of the same type that are similar in colorimetric characteristics and transparency according to this part of ISO 2846 will normally ensure similarity on another substrate.
