Color copying apparatus and method for copying color image based on surface-finishing condition of the copied medium

摘要

A color copying machine is provided with a color signal input unit for inputting red, blue and green signals representing the colors of a document, a recording unit for recording the color picture of an original color picture on the basis of printer control signals for controlling a cyan printing by using a cyan toner, a magenta printing by using a magenta toner and a yellow printing by using a yellow toner and a processing unit which changes the color signals including the red, blue and green signals into the printer control signals related to the cyan, the magenta and the yellow by using a matrix representation in conformity with a predetermined rule to produce cyan, magenta and yellow printer control signals. A surface-finishing mode selecting button allows an operator to select either a glazed finish to the recording sheet or an unglazed finish after recording the color picture thereon. The CPU determines one set of parameters to be used by the processing unit from a plurality of sets of parameters stored in the ROM according to the selected surface-finishing mode. The processing unit modifies the input color signals by using the predetermined parameters, according to the selected surface-finishing mode, and the recording unit records a color picture on a recording medium. The glazing unit glazes, or finishes, the printed recording medium according to the selected surface-finishing mode.
