With the development of the printing industry, the process of continuous progress, UV plate as a "non-contact" inkjet printing high-tech digital printing equipment, it can not be restricted by any materials for full-color printing. General materials can be directly printed with ink, but some special materials will not absorb ink, or ink is difficult to adhere to its smooth surface, the need to use the coating to deal with the surface of the object, so that the ink and printing media perfect combination and a perfect printing effect. The coating must also be able to adhere firmly to the printing medium and blend well with the ink without affecting the final ink on the medium. Can the coating be used in all kinds of printing media? The answer is no! The coating is selected for printing medium and ink. The coating can take many minutes, such as metal coating, ABS coating, leather coating, silicone coating, glass coating, PC coating and so on.
I. glass coating PL:
Suitable for plexiglass, toughened glass, ceramic, ceramic tile, crystal, need to do special treatment, respectively transparent and white two, can do light and matte effect. Resistance to boiling requirements higher, usually with white oil, adhesion is very important, white oil is not too strong, otherwise easy to dissolve the pattern, it is best to spray twice.
Ii. PC coating PC:
A hard material that usually has a difficult adhesion. It is suitable for PS, PP, PVC and other p-type materials.
Iii. Metal coating CP:
Metal, dry quickly; Spraying requirements, surface thickness, otherwise easy to drop; DY: metal, ceramic, a little slower than CP; Suitable for aluminum, copper, tinplate, aluminum alloy and other materials, can also be used in ceramic tile, toughened glass, need to do special treatment, respectively transparent and white two, can do light and matte effect. Mainly is the surface smooth degree, such as ceramics than glass smooth, with DY.
4. ABS coating
CU and ABS vials: acrylic, plastic, bamboo and wood. Pay attention to whether the surface is shell burning. There are many kinds of materials for ABS, which are suitable for wood board, PVC, ABS, gypsum board, thickened kraft paper, acrylic, PS, PVC, ordinary plastic, etc. There are two kinds of transparent and white respectively, which can make light and matte effect. ABS large bottle: according to the customer's materials, determine which one to use, spray requirements, surface uniformity.
5. Leather coating
Suitable for genuine leather, leather, PVC leather, PU leather, transparent and white respectively, can do light and matte effect.
Silicone coating is suitable for silicone and rubber materials. Surface activity is poor, to flame treatment, otherwise adhesion is not enough, flame treatment, with experience, the surface can not spray too thick, otherwise it is not easy to dry!
