Problems solved by technology

[0004] This method is to make better use of the printing characteristics of the squeegee and avoid the reduction of printing accuracy caused by multiple processes. However, at present, this method only exists in the printing of flat products, corresponding to products with three-dimensional shapes, especially toys. There is no successful and effective high-precision and high-definition printing method for such three-dimensional products
[0005] At present, for the pattern or picture printing of three-dimensional products, the pattern or picture is usually pasted on the product, or baked on the product with film. In this case, the pattern or picture on the appearance of the product will cause damage to Some or even all of them fall off, and the appearance is very bad, especially for plastic products, the situation of falling off is even more serious, so most plastic products have no pattern, only dyeing

Embodiment Construction

[0027] The implementation of the present invention will be described in detail below in conjunction with specific applications.

[0028] In this embodiment, the high-precision, high-definition pattern printing of a spherical product is taken as an example for description.

[0029] The pattern that needs to be printed is a world map, that is, the world map is printed on the PU sphere, making it a toy with appreciation value.

[0030] Because a simple spherical body is inconvenient in pattern printing and mold use, in order to facilitate production, the spherical pattern is decomposed into two hemispherical patterns during the printing process, which are produced separately and then synthesized into a whole.

[0031] The overall process of printing and production is as follows:

[0032] 1. To make a film, divide the pattern of the world map into upper and lower hemispheres, and then divide them into two parts, respectively compress the upper and lower hemispheres according to t...

Abstract

This invention relates to a method for printing accurate pictures of stereo-products including processing Pholin, printing, heating, developing and foaming, which integrates the mold production and printing perfectly to print and manufacture patterns and pictures of stereo products and compress them correspondingly so as to print plane patterns to the stereo products.

Description

technical field [0001] The invention relates to a printing method of high-precision pictures, especially a printing method for high-precision graphics or pictures on three-dimensional products. The method has simple process, low manufacturing cost and can produce high-precision pictures. Background technique [0002] Printing originated in China, and has developed to the present: letterpress printing, gravure printing, offset printing, screen printing, photocopying, thermal transfer printing, electrostatic copying and inkjet printing. Among them, the first three printing methods are commonly used, and the printed materials produced by the first three methods account for a large part of the printed matter produced every year. At present, screen printing is usually used for printing that requires high definition and precision. [0003] As described in the patent application 03104191.4, it is a screen printing method that achieves high-precision printing through multiple print...
