Problems solved by technology

[0002] Today, with the rapid development of technology, the surface decoration of printed matter has shown a trend of diversification and artistic development. The original screen printing cannot meet the needs of consumers (the pattern lacks three-dimensional effect and the appearance is single)
In recent years, some mobile phone manufacturers have designed three-dimensional patterns with different patterns as new highlights of mobile phone surface decoration through market research, but printing of such three-dimensional patterns is difficult to achieve in screen printing

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the PC sheet printing process with three-dimensional patterns on the surface of the mobile phone. Its specific process steps are as follows:

[0017] (1) Manuscript production and film output

[0018] Computer processing is carried out according to the design pattern, and then the film is produced by laser phototypesetting technology.

[0019] (2) Plate making of three-dimensional patterns

[0020] ① Stretch the net: Stretch the screen on the screen frame to make a screen printing plate, the stretching angle is 45°, and the tension of the stretching net is 27N / cm;

[0021] The screen adopts 300 / inch high-tension / low-elongation polyester screen, and the screen frame is 950×850 aluminum alloy screen frame. The screen printing plate adopts oblique stretching, and the stretching angle is 45° to achieve clearer lines .

[0022] ②. Photosensitive plate making: put the screen printing plate on the co...

Abstract

The invention relates to a process for printing a sheet with a 3-D pattern on the surface of a mobile phone. The process improves the effect of the 3-D pattern by determining the thickness of a screen printing plate to be between 49 and 51mu, and meets user requirements through once positioning, multiple printing and multiple baking to achieve the effect of the 3-D pattern with different heights.Firstly, transparent ink is printed on an achromatic transparent sheet to increase the brightness, then the transparent ink is printed for multiple times according to the user requirements subsequently, and the viscosity of the ink is controlled at between 16 and 20p, so the nice effect of the 3-D pattern by setting baking parameters is achieved. The process comprises the following steps: 1, making an original pattern, and outputting a film sheet; 2, making a plate for the 3-D pattern (stretching a screen, manufacturing the plate by sensitization, and developing by exposure); and 3, printing the 3-D pattern (preparing the ink, setting the printing parameter, printing and baking). The product manufactured by the process meets the user requirement on the solid effect of the 3-D pattern, thereby improving level of the product, increasing attraction of the product, and improving the economic benefit of the product.

Description

technical field [0001] The invention relates to a sheet material surface printing process, in particular to a sheet material printing process suitable for mobile phones with three-dimensional patterns on the surface. Background technique [0002] Today, with the rapid development of technology, the surface decoration of printed matter has shown a trend of diversification and artistic development. The original screen printing cannot meet the needs of consumers (the pattern lacks three-dimensional effect and the appearance is single). In recent years, some mobile phone manufacturers have designed three-dimensional patterns with different patterns as new highlights of mobile phone surface decoration through market research, but printing of such three-dimensional patterns is difficult to achieve in screen printing. In the process of repeated tests and development, appearance defects such as bubbles and cracks often appear, and to overcome these defects, it is necessary to achiev...
