Abstract

Color target sheet contains standard printed colors from CMYK color space, with ten repeats of same color field on different parts of sheet, with regular dispersal of same color fields over surface. Calibration sheet/target has color fields (A1- L22) and gray scale (GS1-GS24). Colors in individual fields are defined by p cent values for colors cyan, magenta, yellow and black for each color field. Target contains 264 single color fields, 26 colors 19 gray values, colors have main tones repeated eleven times and other colors repeated ten times
