Abstract

PURPOSE:To reproduce a recording picture with an excellent color balance by controlling the number of ink dots for each color according to the output signal of a means of detecting the ground color of a recording paper in a multi-color ink jet recorder. CONSTITUTION:The quantity of a reflected light of each color is detected from a recording paper 3 with detection photosensors 101-103 of a recording paper reader 6 and converted into signals R1, G1 and B1. The quantity of a reflected light of each color component is detected from a color manuscript 2 with detection photo sensors 108-110 of a color manuscript reader 5 and converted into signals R2, G2 and B2. A color signal arithmetic circuit 107 computes C0=a11-a12G1-a13B1- (b11R2-b12G2-b3B2), M0=-a21R1+a22G1- a23B1-(-b21R2+b22G2-b23B2), Y0=-a31R1-a32G1-a33B1-(-b31R2- b32G2+b33B2) to drive a nozzle with color component signals Y0, M0, and C0. This corrects variations in pictures due to difference in the ground color of the recording paper thereby enabling a better color recording.
