Abstract

PURPOSE: To enhance quality of color separated masters and their stability, by allowing a printing master designer to obtain setup conditions in advance with a presetup device, and the operator of each scanner to setup each scanner in accordance with its result.
CONSTITUTION: Original 12 is subjected to enlarged projection on screen 28 with standard light source 26 to design master preparation. The original is removed, ND patch 36 near the original color density is inserted in the light path, and level adjustment of photoelectric converting element 48 is made by switching over inspection light source 16. The original is again placed and patch 36 is removed. The transmitted luminous flux from light source 16 is converted into an electrical signal with element 48, operation unit 54 carries out operation on the basis of this signal, and each dot percentage or density of each of Y, M, C, and BK masters is displayed digitally on display 60. The designer of master preparation compares these indicated values with the designed values and controls them on operation board 56, thus permitting quality of the color separated masters and their stability to be enhanced.
