PRINTER, PRINTING METHOD, AND INK CARTRIDGE THEREFOR

摘要

PROBLEM TO BE SOLVED: To suppress generation of granular feeling while reducing the delivery of three kinds or more of ink which can represent a hue in a predetermined range through mixing. SOLUTION: Recording rate is determined for each color ink from an input gradation data of each color with reference to tables TC, TM and TY and a dot is formed depending on the recording rate. Since the dye density of yellow ink is set higher than a color balanced density, recording rate of yellow Y becomes lower than the recording rate of cyan C and magenta M. Yellow Y has high lightness and the granular feeling is not conspicuous even if the dots are formed sparsely for a region of low gradation data. Since the density of yellow ink Y is increased, the quantity of ink to be jetted from a head is decreased for a required density.
