With the development of the printing industry and the continuous advancement of craftsmanship, UV Print machine as an inkjet printing type high-tech digital printing device that is "non-contact with objects", it can be free from any Material restrictions for full color printing.
The general object material can be printed directly with ink, but some special materials may not absorb ink, or the ink is difficult to adhere to its smooth surface, it is necessary to use the coating to treat the surface of the object, so that the ink Perfectly combined with print media for perfect print quality.
The coating must be firmly attached to the print medium and blend well with the ink without affecting the final appearance of the ink on the media.
Can the coating be versatile on all types of print media? The answer is no! The coating is chosen for the print media and ink. The coating will be divided into several times, such as metal coating, ABS coating, leather coating, silicone coating, glass coating, PC coating, etc., Xiaobian will introduce you to the following common coatings: /p>
First, glass coating
PL: Applicable to plexiglass, tempered glass, ceramics, ceramic tiles, crystal, special treatment, transparent and white, both for bright and matte effects. Resistance to boiling water requires a little higher, usually with white oil, adhesion is very important, white oil should not be too strong, otherwise it is easy to dissolve the pattern, preferably spray twice.
Second, PC coating
PC is a hard material that usually does not easily pass. Applicable to a class of materials beginning with P, PS, PP, PVC, etc.
Third, metal coating
CP: Metal, dry quickly; spray requirements, thick surface, otherwise easy to fall;
DY: Metal, ceramic, slower drying than CP; suitable for aluminum, copper, tinplate, aluminum alloy and other materials, can also be used in ceramic tiles, tempered glass, special treatment, transparent and white Kinds of light and matte effects. Mainly the smoothness of the surface, such as ceramic smoother than glass, use DY.
Fourth, ABS coating
CU, ABS vials: Acrylic, plastic, bamboo and wood. Pay attention to whether the surface is burnt, ABS has many kinds of materials, suitable for wood, PVC, ABS, gypsum board, thick kraft paper, acrylic, PS, PVC, ordinary plastic, etc., respectively, transparent and white, can do light With a matte effect. ABS large bottle: According to the customer's material, it is judged which one to use, spraying requirements, and the surface is even.
V. Leather coating
Applicable to leather, leather, PVC leather, PU leather, etc., both transparent and white, both can be used for bright and matte effects.
Six, silicone coating
For silicone, rubber. Poor surface activity, flame treatment, otherwise the adhesion is not enough, flame treatment, by experience, the surface can not be sprayed too thick, otherwise it is not easy to dry!
