3D optical grating flexible glue printing technology

Abstract

The invention discloses a 3D optical grating flexible glue printing technology. The 3D optical grating flexible glue printing technology comprises the following steps that a heat transfer printing release oil layer is printed on coated paper; a first white ink coating is arranged on the heat transfer printing release oil layer in a screen printing manner; a multi-angle dynamic design/pattern is printed on the first white ink coating in an offset printing manner; the multi-angle dynamic design/pattern is covered with a flexible glue film; a semi-finished product obtained in the previous step is subjected to hot pressing, an optical grating pattern is formed on the flexible glue film, and the multi-angle dynamic design/pattern shows the 3D effect; and the coated paper is stripped, a second white ink coating is subjected to screen printing, and a finished product is obtained through cropping according to the specification. The 3D optical grating flexible glue printing technology has the beneficial effects that technology steps are simple, and the multi-angle dynamic design/pattern can be smoothly arranged on the flexible glue film through heat transfer printing through usage of the heat transfer printing release oil and white ink; PVC and TPU flexible glue films are subjected to hot pressing into an optical grating, a soft presswork which shows the 3D effect through multi-angle appreciation is manufactured, the application range of the presswork can be widened, and the 3D optical grating flexible glue printing technology is not limited in application of simple packaging materials or book printing.

Description

technical field [0001] The invention relates to the technical field of 3D pattern printing, in particular to a printing process for thermally transferring a pattern information layer onto a soft rubber film. Background technique [0002] 3D printing is becoming more and more popular due to its dynamic, three-dimensional, and more dynamic effects, such as product packaging, book printing, etc. In some 3D printing, patterns are printed on paper or other materials and then covered with a lenticular sheet, while others are printed directly on the lenticular. [0003] The announcement number is "CN103895378A", the title of the invention is "Printing Method of 3D Patterns", in which step 1 discloses the production of multi-angle dynamic grating patterns, and step 1 includes making multi-angle dynamic patterns, making grating files, and electrocarving multi-angle dynamic grating patterns Or film, gravure or offset printing, gravure or flexo information medium layer, embossed grati...

AI Technical Summary

Problems solved by technology

In this technical solution, the preparation process is complicated, and the printing process requires high precision, high reject rate, and poor durability of the product.

[0004] In addition, general 3D printing is limited to books or simple hand-made packaging materials, and it is rarely involved in handbags, backpacks and other supplies that require folding box design.
