PROBLEM TO BE SOLVED: To obtain the colorimetric device which efficiently measures the colors of color patches and the printer. SOLUTION: Rectangular color patches C which have relatively long sides along the width are printed in matrix on a sample medium as shown in (A). The colorimetric device measures the colors of the color patches C while moving a head along the width of the sample medium M and it takes a certain time to measure the colors of the color patches C. For the purpose, the sample medium M has the color patches C set to a long-side length longer than the length obtained by multiplying the moving speed of the head by the time needed for the color measurement by the head. Consequently, when color measurement start coordinates are set to 10, 110, and 210 for the coordinates 0, 100, 200, and 300 of the boundaries of the respective color patches C, the colors of the color patches C can be measured without stopping the head. |
