COLOR ADJUSTMENT SYSTEM FOR PRINT OUTPUT, COLOR ADJUSTMENT METHOD AND PRINTER DRIVER

摘要

PPROBLEM TO BE SOLVED: To obtain a color adjustment system, color adjustment method and printer driver in which an overall direction of color correction can be intuitively designated and a color can be easily and accurately corrected as desired. PSOLUTION: A printer driver 10 including a look-up table wherein image data of an RGB system are associated with data about quantities of inks of a plurality of colors. The printer driver 10 comprises: a host computer 2 for calculating print data through interpolation arithmetic and outputting the print data; a printing device 3 for printing on a printing medium the print data output from the host computer 2 while using the inks of the plurality of colors; and a color correction pattern 4 printed on the printing medium by the printing device 3. The color correction pattern 4 includes a pattern presenting, as candidates, a plurality of hues a little different from an arbitrary reference hue and a pattern presenting, as candidates, a plurality of brightness levels a little different from an arbitrary reference brightness level. On the basis of the pattern of a candidate selected in the color correction pattern 4, the printer driver 10 corrects the corresponding relations of the respective color ink quantities in the look-up table 11.
