Abstract

PURPOSE:To simplify a black-print signal generating circuit by separating original picture elements in three primary colors, by converting each primary-color signal into a digital signal, and by assigning a dot matrix according to the thickness of each color. CONSTITUTION:Three primary color signals 1-1-1-3 each showing thickness by a voltage are converted into digital signals by A/D converters 26-1-16-3 respectively, and they are inputted to control circuits 41-1-41-3. A control circuit 41 selects a dot pattern, which corresponds an input signal 27, in an ROM42 to output it, dot by dot, and also stores this pattern; and an AND circuit 32 generates a black-print signal 40 by the dot-by-dot output signal 7. The output signal 7 and black-print signal 40 are passed through a delay circuit 8 and a modulating circuit 9 to drive a head 13, and black dots are recorded as superposed where three primary colors Y, M and C are recorded as superposed in a matrix.
