<P>PROBLEM TO BE SOLVED: To solve the problem of increasing the cost due to a complex structure of hardware compensating temperature change. <P>SOLUTION: In an inkjet printing system, since the viscosity of color inks depends on a temperature, the color inks increase or decrease depending on a temperature and may fail to reproduce original colors. A temperature sensor 31f provided in a printer 31 measures the temperature of the printer 31 (Step S220). By rewriting a color conversion lookup table by using a color correction lookup table corresponding to the temperature measured (Step S240), colors are corrected into dense colors when the weight of color ink drops decrease due to a low temperature (Step S250). When the weight of color ink drops increase due to a high temperature, colors are corrected into lighter colors (Step S250). Printing is performed (Step S270) through binarization (Step S270), the total quantity of color inks used becomes an original quantity not depending on a temperature. Consequently a temperature compensation can be performed by a color correction process according to a temperature. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
