(1) When the color sample registration/changing means 52 system starts up, the main menu S1 shown in FIG. 2.1 is displayed on the CRT. If the color sample registration/change S2 is selected here, the process enters the color sample registration/change means 52 shown in the flowchart of FIG. As shown in this figure, the color sample data is Specification No.5
2 and color number (what color) is managed in S3. The total number of color sample data that can be registered is 10,000 (approximately 30,000 types) with an average of 3 color samples per item (assuming that there is)
It is. Conventionally, it was possible to register only up to class 20Il in a color difference meter. As shown in FIGS. 2 and 2, in the color sample registration/changing means 52, after the color sample measurement S7, the color difference of the same color is directly measured in the same manner as in the operation of a conventional color difference meter. It is possible to move on to the measurement SIO, or, as one of the features of this system, it is also possible to register only a large number of color samples in advance and then register the color difference using the color difference registration means 54.

The total number of color difference data that can be registered is 10,000, assuming that each item has an average number of 5, a number of windings of 6, and a number of colors of 3. The feature of this color difference registration means 54 is that the color sample data of the printed matter to be measured is automatically called up by the color sample data call in S3 shown in FIGS.
By setting the color sample data in step 6 to the color difference meter, the color sample data will be automatically set to the color difference meter. This allows the operator to measure the color difference of printed matter by simply registering the printing color sample once. Conventionally, the procedure was to measure the color difference of printed matter. Therefore, it was thought that dirt, discoloration, etc. due to changes in color samples over time would affect color difference measurement, but this system can prevent such problems.
