With the improvement of people's requirements for product packaging and decoration, the application of water transfer printing has been continuously developed, and the use is getting wider and wider. The principle of indirect printing and the perfect printing effect solve the problem of surface decoration of many products, mainly used for the transfer of various types of ceramics, glass flower paper, etc.
-, A wide range of transfer objects
1. Printed ceramic flower paper. It can be used for the production of patterns of various daily-use ceramics such as ceramic tableware, ceramic water ware, etc., and can also be used for the production of architectural tiles such as waistline, decorative tiles, decorative ceramics and so on.
2. Printed glass flower paper. Can be used for glass water utensils, glass bottles, advertising cups, various glass containers and decorative glass.
3. Print helmet paper. It is widely used in the production of surface patterns on motorcycle helmets and safety helmets.
4. Sports applique. Such as the production of trademarks and logos on the surface of tennis rackets, fishing rods, etc .; the decals of metal pipe fittings, such as the design and text of bicycle and motorcycle pipe fittings; the production of decals on the surface of toy car models, the printing of wooden flower paper; and the stylish tattoo stickers ; Other decals that are difficult to print directly on.
Second, the water transfer process
Making water transfer printing paper → flower paper soaking → pattern transfer → drying → finished product
1. Water transfer printing paper production. After processing the computer according to the required pattern, output the negative plate, and then print various colors on the water transfer base paper (specially processed paper does not need to be processed), and then print the cover on the printed base paper oil. Another method is to use a color laser printer to print the pattern directly on the water transfer base paper and then perform water transfer.
2. Flower paper soak. Put the printed flower paper in water, soak it for 30 s and take it out of the water, and wait for it to be transported. Note that the soaking time should not be too long, otherwise it will dissolve the glue on the paper surface.
3. Pattern reposting. First, the surface of the object to be transferred is treated, and then the soaked floral paper is transferred to it, then the excess water is scraped off and dried.
4. dry. Metal, ceramic and glass items are placed in the oven and baked at 140 ° C for 20 min; plastic items are baked at 70 ° C for 60 min; candles, helmets or strengthened glass are not baked.
5. Finished product. Spray another layer of transparent varnish on the floral surface of the baked goods, and after 12h drying, make the floral surface and the decoration permanently combined. If you don't do this process, it can be done, but the fastness is not good.
All in all, printing manufacturers can use the speciality of water transfer to develop special business according to their business needs.
