Embodiment 1

[0027] A film silk screen printing process, specifically comprising the following steps:

[0028] Step 1, film electroplating. Specifically: use Guangchi 2350 electroplating equipment, set parameters: baking temperature: 20±10°C, initial vacuum degree of coating: (2.0±0.5)E-3Pa, initial vacuum degree of melting material: 8.0E-3Pa.

[0029] Step 2: During film electroplating turnover, the film is covered with a layer of anti-static protective film (the material is FZ-003S-02, and the peeling force is 2.5g / N), and then the screen-printed film is manually torn off to remove dust. Specifically: tear off the anti-static protective film on the upper end of the film from one end to the other, then hold the non-textured areas on the left and right sides of the film with both hands, bend the film into a bow shape, and gently tap the other side towards the front of the table to place the film on the Dust spots due to plating turnover shake off.

Abstract

The invention provides a film silk screen process. The film silk screen process specifically comprises the following steps that (1) film electroplating is conduced; (2) during film electroplating transferring, a film is coated with a layer of anti-static protective membrane, and then the film to be subjected to silk screening is subjected to manual dyestripping and dust removal; (3) a LOGO1 is silk-screened on the preset position of a film product, and then pre-baking is conducted; (4) other LOGOs are silk-screened on the preset position of the film product according to the method in the step3, and then pre-baking is conducted; (5) after the multiple LOGOs are silk-screened, the film is fixedly baked at the temperature of 70-80 DEG C for 8-12 minutes; (6) after baking, the film is coatedwith a layer of anti-static protective membrane, and then secondary manual dyestripping and dust removal are conducted; (7) a main color is silk-screened; and (8) a silk screen roller is normally started for printing. According to the film silk screen process, the problem of poor white points of the finished film containing the multiple LOGOs can be effectively solved, the yield of the finished film is increased, product delivery is met, and the process ability of the film is greatly improved.

Description

technical field [0001] The invention relates to the technical field of silk screen printing, in particular to a film silk screen printing process. Background technique [0002] At present, some film products need to screen-print LOGO characters several times after electroplating. In order to prevent damage to the electroplating layer, the rollers of the screen printing machine cannot be turned on to remove dust during silk-screen LOGO, resulting in dust spots and dirt on the film that cannot be removed. Defects of dots and dirt appear as white dots, which cannot be effectively improved, resulting in a high proportion of white dots in the finished film, and a low overall yield rate of the finished film, which cannot meet the delivery of finished products, resulting in customer complaints and loss of orders. [0003] Therefore, there is an urgent need to optimize and improve the current production process, reduce film white spot defects, improve the yield rate of finished film...
