Is desired.

Conventionally, for example, when performing color printing,
It is possible to measure the color tone of a printing medium printed at a predetermined stage (for example, one lot) in a printing process by using a color difference meter, and measure the color change by digitizing the color tone and comparing it with, for example, a reference value. it can. By performing the necessary color setting in the next printing in accordance with the color change, the variation of the color tone can be reduced, and the color tone can be unified and stabilized.

[0004] A color difference meter numerically measures the color difference of an object as the difference in perceived color under the same light source and the same illumination.
Reflected light from an object is collected by an integrating sphere and measured by a phototube. A predetermined number of predetermined locations are measured on a printing medium on which the same content is printed. That is, if there is no change in the color tone as a result of the measurement by the color difference meter, the color setting is not changed, and if there is a change, the color setting is performed to correct the color setting, thereby enabling color printing with a stable color tone. It is.
