Description

Printing method combining photoetching technology and digital jet printing

Technical Field

The invention belongs to the technical field of printing, and particularly relates to a printing method combining a photoetching technology and digital jet printing.

Background

The photoetching technology and the digital jet printing technology are printing technologies commonly used in the printing field, but when the technologies are used independently, the technologies have the defects that:

when the photoetching technology is used independently, the visual effect is better, but no touch feeling exists;

when the digital jet printing technology is used independently, the touch effect is good, but the visual effect is not so strong;

how to realize multiple light variation and light variation synergy on printed matters and have strong touch feeling is a problem to be solved urgently in the technical field.

Disclosure of Invention

In view of the above technical problems, the present application provides a printing method combining photolithography and digital jet printing, and the specific technical scheme is as follows:

a printing method combining photoetching technology and digital jet printing comprises the following steps:

step 1: printing a pattern design;

step 2: manufacturing a printing design file according to the printing pattern designed in the step 1:

A. manufacturing a real-bottom file: manufacturing software as AI, using C, K channel, adjusting the percentage of C, K in the solid file according to the thickness of the digital ink-jet gloss oil;

B. line file production: manufacturing software as AI, using C, K channel, and adjusting the thickness of the line according to the design requirement;

C. manufacturing a printed file: combining the real bottom file and the line file to be used as a printing design file;

and 3, step 3: carrying out photoetching plate making and plate copying according to the printing design file;

and 4, step 4: printing;

and 5: and selecting corresponding gloss oil to carry out digital jet printing according to the printing and photoetching pictures and texts.

Preferably, in the step 2, the percentage correspondence between the thickness of the digital inkjet gloss oil and the C, K in the solid document is as follows: when C, K100% is 100%, the thickness of the gloss oil formed by one-time ink-jet forming of a machine is 50 μm, and the thickness of the gloss oil decreases with C, K% of the percentage on the basis of 50 μm.

Preferably, in the step 2, the ratio of the distance between lines to the thickness of the lines is 1: 1.5; the thinnest lines of the frame body are 0.04MM, and the thinnest lines of the path are 0.01 MM;

preferably, in the step 5, the gloss oil is common UV digital gloss oil.

The invention has the beneficial effects that: by combining the photoetching effect and the digital effect, the digital jet printing effect is superposed on the original photoetching effect, multiple light variation and light variation synergy are generated, and the product has strong touch feeling, so that the anti-counterfeiting performance and the visual decoration performance of the product are greatly improved. Not only can improve the decorative performance of the product in the aspect of photoetching technology, but also can ensure that the photoetching effect has touch feeling and the anti-counterfeiting performance is stronger. The photoetching printing and the digital printing can be realized by adopting one printing file, and the combination effect of the photoetching printing and the digital printing is also ensured by adopting the same file.
