发明名称 IMAGE FORMATION DEVICE AND GRADATION CORRECTION TEST CHART
摘要 <p><P>PROBLEM TO BE SOLVED: To allow correct visual determination of contrasting density between a standard density pattern of yellow and a reference density pattern by applying a contrast effect pattern of a color having a contrast effect with respect to yellow. <P>SOLUTION: A gradation correction chart generation part 215 generates gradation correction test chart print data based on a print instruction of a gradation correction test chart; a printing part 22 prints, based on the gradation correction test chart print data after screen processing by a screen processing part 217, the gradation correction test chart where a standard density pattern having densities used as standards of respective colors such as Y, M, C and a plurality of reference density patterns having respective densities of respective colors compared with the standard densities are printed by being arranged side by side, and a contrast effect pattern comprising dark blue high in a chroma contrast effect to yellow is also printed around the standard density pattern of yellow and the respective reference density patterns. <P>COPYRIGHT: (C)2010,JPO&INPIT</p>
