Frosted glass screen printing and finishing
Frosted glass screen printing can be manual and mechanical printing in both ways. General screen printing machinery is divided into fully automatic or semi-automatic machine. Fully automatic multi-color brush set purposes, equipped with photocell control of the automatic stop device, is ideal for printing glass products and all kinds of sheet. The choice of scraper mainly depends on its acid resistance and hardness, in general, mechanical printing speed, easy operation, high printing precision, but equipment investment. Contrast with manual printing. To ensure the quality of manual printing, the key is to control the thickness of the screen printing frosted, frosted to maintain a certain time. In order to ensure that the operation of the scraper during the printing process is unobstructed and the residual printing paste is stored in a certain position in the printing plate, it should be considered that the inner screen should be larger than the area occupied by the printed graphic in the plate making process. General plate to set aside the sky, the distance between the foot and left and right in the direction of the squeegee should be retained (15 ~ 20) cm, both sides of about 10cm; made of polyurethane rubber squeegee is very popular in recent years, high-quality Plastic squeegee, the color is transparent light yellow. Characterized by solvent resistance, abrasion resistance, high oil resistance, high strength, good resilience. Molding methods of polyurethane rubber casting, calendering and thermoforming three, domestic plastic scraper and more use of casting. Squeegee purchased in batches are generally in rolls, printing according to the actual needs of the size of the crop. Frosted printed with a thickness of 1cm, Shore hardness of 65, aluminum alloy handle material, the light and hardness of the material in order to facilitate the balance of force. Stamp pad to be straight, scraping India efforts should be uniform, robust, methodical scraping, scraping scraping to prevent ghosting or paste version and other problems. Before the official printing, the first trial printing, in order to test the screen, substrate position, scraper angle, intensity, stroke is appropriate to make the necessary adjustments before the official print. After printing, let the printed material remain on the glass surface, the time should not be too long, otherwise the printed material will increase the amount of corrosion inconvenient to clean, but also affect the entire glass surface frosted effect, resulting in non-uniform. Frosting in the process of printing should be careful not to splash the slurry on the body due to India as a strong acidic material, will burn the skin. After the printing water rinse the ink, leaving traces of corrosion, if necessary, can be used to wipe the brush, the printed glass placed on the bracket for natural drying after the finished product.
