Abstract

PURPOSE:To enable one hard copying machine to obtain both monochromatic and color hard copying by providing both circuits of color conversion and monochromatic conversion in a hard copying machine. CONSTITUTION:Before hard copying, it is decided whether color copying or monochromatic one and a flip flop 10 is set or reset by a CPU 6 according to the decision. And, in the case of color hard copying, a color conversion circuit 3 is made to operate and in the case of monochromatic hard copying, a monochromatic conversion circuit 9 is made to operate and also, a circuit that is not operated is set in a prohibition state to operate. So that the CPU 6 controls all of the machine, it gives the indication of color conversion or that of monochromatic conversion to a control circuit 5. And also, it controls to output color information or monochromatic information that is stored at a hard copying memory 4 from an output port 7 through a bus 8.

[Problems with blue strategy technology] However, in the above method, when copying a specific color (
It had the disadvantage that it was not practical and that it took too much time to make copies. If you think about it, color hard peas are used as rimple,
The remaining required number of copies can be made by copying from a monochrome hard copy (this can be done between color hard copy J and type I4). Two devices were required: a copying device and a 1-heart copy device, which had the disadvantage that the speed was high, and the printability of color hard copies and monochrome hard copies differed. .
