Spectrophotometric Instrumentation for Graphic Arts.

The use of a spectrophotometric measurement in the graphic arts has been discussed for some time. Until now, one of the obstacles has been the lack of adequate instrumentation for the specific needs of this application. The newest approach for an easy and exact off-press and on-press measurement has been explored. The new instrumentation of GRETAG is easy to handle, and incorporates the possibilities of controlling standard inks and special inks in one unit. This performance has been achieved by using the newest technologies in electronics and optics. The new impressive reduction in dimensions and price have brought spectrophotometers within the range of densitometers. A new era in press and quality control has been herewith initiated. standard inks and special inks in one unit.
