しておく方が目立ちにくい。Next, the operation of the present invention will be described. The light source for illuminating the original of the black-and-white copying machine is mostly bluish and has little reddish light component. Therefore, a reddish color is likely to appear black in a copy even if it is a relatively pale color. Therefore, in the present invention, a pattern for preventing copying is printed in a reddish color on the printing paper. Since it is not preferable to print a very clear pattern on the printing paper, the pattern is printed in a color having a relatively high lightness. In addition, it is less noticeable if the line width of the pattern is narrowed.

By printing a pattern with a hue similar to the complementary color of the reddish color used to print the pattern, it is possible to prevent the entire image from appearing reddish. Although the expression "printing paper" is used in the present invention, it is not limited to the paper for printing books, and the same effect can be obtained by using it as copy paper or printer paper.

コピー機では殆どコピー不能の書物が作れる。When printing a technical book or the like, if the printing paper of the present invention is used and blue ink or the like is not used for the character portion, the reflectance of the light of the character portion is increased, and it is for ordinary black and white. With a copy machine, you can make almost uncopyable books.
