Technique for transfer printing on film wrapped around or covered on products made from nonmetallic material

Abstract

A transfer process includes using bottom pigment directly to produce nonmetal material product, grinding and cleaning the product surface, laying the wrapping film on water surface with printed drawings being faced up, spraying the activating reducer on the wrapping film, pressing the product down under water for 20 minutes as per drawing positions in order to transfer the drawing from the film to the product then carrying out finishing treatment for final product.

Description

technical field [0001] The present invention generally relates to a printing process, in particular to a coating film transfer printing process for transferring non-metallic inorganic material items with irregular surfaces. Background technique [0002] The existing transfer printing process can usually only transfer calligraphy and painting patterns to objects with regular shapes, such as planes, spherical surfaces, cylindrical surfaces, etc., but cannot transfer calligraphy and painting patterns to objects with complex and changeable surface shapes. The State Intellectual Property Office of China published the patent number 01204526.8 on February 27, 2002, a utility model patent named "multi-layer film coated with random images", which discloses a multi-layer film coated with random images. The film comprises a base material, a water-soluble polymer layer, and a waterproof and water-resistant image-receiving layer. The water-soluble polymer layer is located on the base mat...

AI Technical Summary

Problems solved by technology

The above-mentioned "multi-layer film with random image coating" has a multi-layer film body, its production process is relatively complicated, and the cost of materials is relatively high. It is necessary to remove the substrate before it can be used during transfer printing, which increases the difficulty of the transfer printing process. , because the removed base material is difficult to handle, and a large amount of waste will be generated, which will pollute the environment

Although the existence of the waterproof and water-resistant image-receiving layer reduces the degradation rate of the water-soluble polymer layer, the waterproof and water-resistant image-receiving layer itself has poor flexibility and a high rate of film rupture, which causes defects in the transfer pattern and causes Increased production costs
