DEVICE FOR OUTPUTTING COLOR PRINTED IMAGE, DEVICE FOR GENERATING COLOR PRINTED IMAGE DATA, COLOR CHART AND STORAGE MEDIUM WITH COLOR CHART DATA STORED

摘要

PPROBLEM TO BE SOLVED: To prepare a highly accurate gradation correction curve and a profile of an output device by accurately measuring the value of each patch constituting a color chart. PSOLUTION: A plurality of single color patches 76C, 76M, 76Y and 76K and a gray patch 76G are formed in a patch output area 70 of output paper 68, the color chart is folded at a folding guide line 74, and a margin area 72 is thereby overlapped on a rear face part of the patch output area 70. The density value and colorimetry value of each of the single color patches 76C, 76M, 76Y and 76K and the gray patch 76G are measured in this state to prepare a gradation correction curve on the basis of the measured values.
