Abstract

PURPOSE:To enable automatic, rapid and accurate measurement of color of a printed matter without relaying on the experience and intuition of a technical expert in color mixing by detecting printed color by means of a densitometer and indicating the same as color-representing data on an indicating device. CONSTITUTION:The densitometer 1 generates signals for cyanogen C, magenta M, yellow Y and white W in accordance with the respective density and each of density signals (c), (m), (y) and (w) is led to CPU of a microcomputer 11. Color-representing data of L, (a) and (b) of a hunter corresponding to each of density signals (c), (m), (y) and (w) are memorized in each address of RAM24 of the computer 11, these color-representing data are memorized in the address of a videodrum 26, further impressed on a television receiver 25 and indicated as a color- representing figure on a screen.
