Abstract
In image formation, one of a plurality of print modes having different allowable print-material discharge amounts is selected. Color image data inputted by an image generator is converted by a LOG converter into CMY data. An UCR & black-generation processor performs density control on the CMY data by each color component, and performs under-color removal and black-generation processing on the density-controlled image data. The UCR & black-generation processor controls a total amount value of the output image data, based on the allowable print-material discharge amount of the selected print mode. The obtained image data is &ggr; corrected and binarized, then outputted to a printer.
