Abstract

G7 process is a new calibration method based on GRACOL7 standard. Unlike the traditional process, it is based on the technologies of Computer-to-Plate (CTP) imaging and spectrophotometer detection and the gray balance can be controlled better in offset printing process. G7 process is a revolutionary process from proofing to printing in offset. However, in flexographic printing, the problems of dot gain and small dots losing are more serious and ink layer is thicker than offset printing, which makes tone reproduction in flexographic printing quite different from offset printing. Therefore, the G7 process, which is usually used in offset printing, cannot achieve gray balance. By adjusting the plate making and compensation parameters through experiments, this paper gives a better solution to the color deviation in G7 process, which is used in flexographic printing.
