Water transfer printing technology is a kind of printing that uses water pressure to hydrolyze the transfer paper plastic film with colorful pictures. The difference and advantage of water transfer printing compared with other printing lies in: water transfer printing can be used to various processed products. Raw materials and shapes.
There are two types of water transfer skills: one is water mark transfer, and the other is water drape transfer technology. The former mainly completes the transfer of text and pictures, while the latter tends to perform a perfect transfer on the entire product surface. The coating transfer technology uses a water-based film that is simply dissolved in water to carry graphics and text.
Because the water coating film has excellent tension, it is very simple to form a graphic layer around the product surface, and the product surface is like spray paint to get a world-wide difference in appearance.
It is covered on workpieces of any shape to solve the problem of three-dimensional product printing for manufacturers. Curved drape can also add different textures to the product's appearance, such as leather, wood, jade and marble, etc., and it can also avoid the vacant positions that often appear in general layout printing.
And in the printing process, because the appearance of the product does not need to be in contact with the printing film, it can prevent damage to the appearance and integrity of the product. Water transfer printing with a specially chemically treated film, after printing the desired color texture.
Flat delivery on the surface of the water, using the effect of water pressure to evenly transfer the color texture picture on the product surface, the time coating film will automatically dissolve in the water, after washing and drying, then apply a layer of transparent protective coating At this time, the product has shown a world-wide difference in visual effects.
Water transfer printing process:
Making water transfer decals → soaking decals → reposting pictures → boring → products
⒈The production of water transfer printing paper. After computer processing the required pictures, the printing plate is output as a negative film, and then printed in various colors on the water transfer base paper (the specially processed paper does not need to be processed), and the cover is printed on the base paper with the printed picture Oil. Another method is to use a colorful laser printer to directly print the picture on the water transfer base paper and then perform water transfer.
⒉Decoration paper soaking. Put the printed flower paper into the water, soak it for 30s and take it out of the water. Be careful not to soak for too long, otherwise it will dissolve the glue on the surface of the paper.
⒊Picture reposting. Firstly, the surface of the object to be pasted is processed, and then the soaked decals are reposted on it, and then the excess water is scraped off to make it dry.
⒋Dry. Put metal, ceramic, glass and other types of items into the oven and bake at 140 for 20 minutes; plastic items are baked at 70°C for 60 minutes; candles, helmets or tempered glass are not baked.
⒌Products. Spray a layer of transparent varnish or matte oil or rubber oil on the surface of the baked goods, and dry it for 12 hours, so that the surface and decoration can be permanently combined. If you don’t do this project, Yes, but the fastness is not good;
