Embodiment 1

[0027] A film screen printing process specifically includes the following steps:

[0028] Step 1, film plating. Specifically: using Guangchi 2350 electroplating equipment, setting parameters: baking temperature: 20±10℃, initial vacuum degree of coating: (2.0±0.5) E-3Pa, initial vacuum degree of melt: 8.0E-3Pa.

[0029] Step 2. When the film plating turnover, the film is covered with a layer of anti-static protective film (material is FZ-003S-02, the peeling force is 2.5g / N), and then the silk-printed film is manually torn to remove dust. Specifically: tear off the anti-static protective film on the upper end of the film from one end to the other, and then hold the untextured area on the left and right sides of the film with both hands, shape the film into a bow, and gently tap the other side toward the front of the table to put the film on Dust spots caused by electroplating turnover are shaken off.

[0030] Step 3. Silk-print the designed LOGO1 in the preset position on the film p...

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 technology, in particular to a film screen printing process. Background technique [0002] At present, some film products need to screen LOGO characters multiple times after electroplating. In order to prevent damage to the plating layer, the screen printer roller cannot be turned on to remove dust when the LOGO is screen printed, resulting in film dust spots and stains that cannot be removed. Poor spots and stains are shown as white spot-like defects, which cannot be effectively improved, resulting in a high proportion of defective white spots on the finished film, and a low overall yield of the finished film, which cannot meet the delivery of the finished product, 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 spots, improve the yield of finished film, and meet produc...
