Abstract

PURPOSE: To make a plate without using color photography, by reading out alternately the odd and even number fields of reproduced TV signals in one frame from the memory in synchronization with the plate making scan, converting them to color signals for printing and feeding to the scanner.
CONSTITUTION: One frame of color TV signal reproduced from a VTR 1 or the like is stored in a frame memory 2. The contents of the storage are alternately read out in each odd and even number field through a signal converting circuit 3 being controlled by a rotation synchronizing circuit 5 in synchronization with the scanning of a plate making scanner 6 to become R, G, B signals for color TV rearranged in the sequence of plate making. These signals are further separated into color signals of yellow (Y), magenta (M) and cyan (C) for plate making by a signal color separating circuit 4 and are fed to the scanner 6. Therefore, the reproduced color TV signals form a video image, and a plate may be made by conversion of reproduced color TV signals, without forming color photographs. As a result, color image plates free from deterioration in the resolution, hue and gradation may be made.
