AI Technical Summary

Benefits of technology

This technology allows for creation of colored images without being restricted or affected by any single type of material. These colored images have specific features such as their appearance like they look similar if viewed at right angles compared to how well an untrusted counterpart looks upwardly through them. They also allow users to see hidden indications about fake items appearing during production rather than showing themselves inside outdoors. Overall this makes these displays effective against forgery while maintaining high quality imaging capabilities.

Problems solved by technology

The technical problem addressed by this patented technology is that existing fluorescence inking can only print one color pattern on paper or card without any visual appeal for multi-toned designs like flower arrangements or symbols.

Embodiment 1

[0041] figure 1 It is a flow chart of a printing method of a color fluorescent effect anti-counterfeiting pattern provided by an embodiment of the present invention.

[0042] refer to figure 1 As shown, the printing method provided in this embodiment is used to print corresponding color anti-counterfeiting patterns on printed matter. The printed matter here refers to banknotes, cards, fuel tickets, financial certificates, etc., and also includes some high-end gifts with anti-counterfeiting requirements. On the outer packaging or on the gift itself. The printing method comprises the steps of:

[0043] S1. Invert the color original image to be printed.

[0044] Through color inversion processing, a negative image corresponding to the original color image is obtained, and the color of each color point on the negative image is complementary to the color of the corresponding color point on the original color image.

[0045] S2. Perform color-separation processing on the negativ...

Abstract

The embodiment of the invention provides a color fluorescent effect anti-counterfeit pattern printing method and system. The method and the system are specifically used for conducting color invertingtreatment on a to-be-printed color original pattern, and a shadow pattern corresponding to the color original pattern is obtained; the shadow pattern is subjected to color separation treatment, and aplurality of unicolor patterns matched in position are obtained; a plurality of printing plates corresponding to each unicolor pattern are manufactured, each printing plate comprises a plurality of color points, the color points, corresponding in position, on the multiple printing plates form a color unit, and the color points of the color unit are adjacent and are connected; and color separationoverprinting is conducted through the multiple printing plates, and each printing plate correspond to one kind of fluorescent ink of a color effect. The color units on a printed product are composed of the printing points different in color effect, thus, different colors can be formed when people see, the printed product displays an anti-counterfeit pattern with the color fluorescent effect, and the problem that an existing anti-counterfeit pattern is limited to unicolor patterns is solved.
