Many acquisitions are required, which leads to high manufacturing costs.

Therefore, an object of the present invention is to provide a multicolor printing method capable of efficiently providing a lace pattern having a different color tone according to each part of the pattern, both in terms of equipment and process.

[Means for solving the problem]

In the multicolor printing method for a synthetic resin lace pattern of the present invention, a color tone A suitable for the pattern is applied to a predetermined portion of the pattern on the synthetic resin lace pattern on which the pattern is formed in a desired shape. (Printing relief printing), and then, on a predetermined portion of the portion where the color tone A is printed and a predetermined pattern portion where the color tone A is not printed, a color tone B suitable for the pattern is applied to another printing plate cylinder (intaglio). Thus, a portion of the color tone A, a portion of the color tone B, and a portion of the mixed color C in which the color tones A and B are mixed can be obtained by performing the print forming.

[Action]

Thus, in the multicolor printing method of the present invention, the color tone A is printed by the first printing plate cylinder (intaglio), and the color tone B, and the color tones A and B are printed by the second printing plate cylinder (concave plate). Are mixed, and the mixed color C is printed respectively. By printing twice, one pattern can be printed in three colors in multi-color. Usually, for printing three colors, three plate cylinders and three color inks are used. What is needed can be represented by two plate cylinders and two colors of ink. further,
When the ground color of the synthetic resin lace is added, it is possible to express a total of four colors only by printing twice.
