Embodiment Construction

[0023] The core of the present invention lies in: using the special treatment of the background color and superimposing it with the color of the ink used to print the pattern to produce a special metallic texture.

[0024] The present invention proposes a printing method for superimposing inks on different background colors, such as figure 1 Shown:

[0025] S1, spraying the product, adding different amounts of metal powder and / or pearl powder to the primer, so as to obtain metal effects and / or pearl texture effects with different textures, which appear to be of higher grade;

[0026] In addition, the color of the primer can be adjusted according to the needs, so as to obtain metal and pearl texture effects of different colors;

[0027] S2, spray a layer of special coating on the surface of the primer, and then dry it;

[0028] This special coating can absorb moisture, which can be a transparent adhesive layer, similar to the adhesive layer on the surface of photo paper, whic...

Abstract

The invention discloses a printing method and a printing device for overlapping printing ink on different bottom colors. The method comprises the following steps of: adding metal powder into a primer with the selected color; spraying the primer on a product; spraying a special coating on the surface of the primer and drying; and according to the color of the primer, printing a pattern on the special coating by selecting the relevant color and drying. In the method and the device, a special metal feeling is generated by performing special treatment on the bottom color and overlapping the bottom color with the color of the printing ink used by the printed pattern; and at the same time, the special coating makes the color more stable and an ultraviolet (UV) film is covered to avoid wear.

Description

technical field [0001] The invention relates to printing technology, in particular to a printing method and device for superimposing ink on different background colors. Background technique [0002] When decorating communication products, such as printing decorative patterns or colors on the casings or back panels of mobile phones, PHS and other terminals, the existing common practice is to first print a set of white background colors (a white color block), including terminal The color area needs to be printed on the shell or back panel, and then print CMYK four-separation color on the white background color, so as to handle rich colors; of course, if you print on other colored materials, you don’t want CMYK four-separation color stacking To go up, it is also necessary to print the white background color first. [0003] However, when this traditional processing method is used for pattern printing on colored communication products, the actual color effect is not good, and wh...
