ABSTRACT:
In an image reproducing system, a memory stores B (Blue), G (Green) and R (Red) color component data instead of color separation data Y (Yellow), M (Magenta), C (Cyan) and K (Black) thus permitting the use of a reduced storage capacity memory. The B, G, R signals are converted to Y, M, C, K for output to a recording module, while internal processing is performed on the B, G, R signals. Screen tint generation or flat tone generation operations are performed on the B, G, R data as needed, at least one of the B, G, R signals being specially encoded to identify generation of a flat tone.
