Process and application of PVA water transfer printing

u003cpu003eWater transfer printing is also called curved surface water coating. Its function is to treat the three-dimensional curved surface of irregular objects-it is a whole surface printing. Use pure natural patterns, such as peach wood, marble, jade, leopard skin, markings, etc. After the object is processed, the color is vivid and the image is vivid. Achieve the effect of false and true. Completely change the surface texture of the object, and the processed product greatly appreciates. u003cbr /u003eu003cbr /u003eWater transfer technology is called a more environmentally friendly technology, and it is also the most emerging high-efficiency printing production, probably related to its separation from the ink in the printing process. The key to the water coating technology is the water-capacitive carrier PVA film. u003cbr /u003eu003cbr /u003eThere are thousands of patterns for customers to choose from, such as imitation wood grain, PVA embroidered water-soluble film marble pattern, jade pattern, leopard pattern, check pattern, pattern, camouflage pattern, etc. It can also design, make plates, and print various designated patterns on behalf of customers. u003cbr /u003eu003cbr /u003eWater transfer uses water pressure and activator to dissolve and transfer the peeling layer on the water transfer carrier film.u003cbr /u003eThe basic process is: 1) Film printing: on polymer film Print various patterns;u003cbr /u003eu003cbr /u003eExpansion of the film: let the film lay flat on the water, and wait for the film to stretch and level;u003cbr /u003eu003cbr /u003eSpray primer: many materials must be coated A layer of adhesive, such as metal, ceramics, etc., if the PVA embroidery water-soluble film wants to transfer different patterns, different background colors must be used, such as brown, brown, ocher, etc. for wood grain, and white for stone grain; u003cbr /u003e4) Activation: Use a special solvent (activator) to activate the pattern of the transfer film into an ink state; u003cbr /u003eu003cbr /u003e5) Transfer: Use water pressure to print the activated pattern on On the printed object;u003cbr /u003eu003cbr /u003eWashing: Wash the remaining impurities of the printed workpiece with water;u003cbr /u003eu003cbr /u003e7) Drying: Dry the printed workpiece, the temperature depends on the material It depends on the quality and melting point;u003cbr /u003eu003cbr /u003e8)Spray paint: spray transparent protective paint to protect the surface of the printed object;u003cbr /u003eu003cbr /u003e9) Drying: finish spraying the finish The surface of the object is dry. u003cbr /u003eu003cbr /u003eThere are two types of water transfer technology, one is water mark transfer technology, and the other is water drape transfer technology. The former is mainly used for printing text, icons and pictures. Transfer, the latter tends to perform a complete transfer on the entire product surface. u003cbr /u003eThe coating transfer technology uses a water-soluble film that is easily soluble in water to carry graphics and text. Due to the excellent tension of the water coating film, it is easy to wrap around the surface of the product to form a graphic layer. The surface of the product has a completely different appearance like spray paint. u003cbr /u003eThe drape transfer technology can drape color patterns on workpieces of any shape, solving the problem of three-dimensional product printing for manufacturers. Curved surface coating can also add different textures on the product surface, such as leather texture, wood texture, jade texture, and marble texture.u003cbr /u003eAt the same time, it can also avoid the vacant position that often appears in general board printing. And in the printing process, because the product surface does not need to be in contact with the printing film, damage to the product surface and its integrity can be avoided. u003cbr /u003eu003cbr /u003eApplication: Supplies: instrument panel, control panel, tissue box, teacup holder, disk holder, rear view mirror frame, operating handle, car lock, etc.; electronic products: telephone, pager, video recorder, etc. , Audio, mouse, clocks and other household items: sofas, coffee tables, cabinets, chandeliers, ashtrays, vases, display containers, etc.; daily-use products: luggage decorations, tableware handles, glasses, pens, pen barrels , Calendar stands, art frame, rackets, accessories, cosmetic pencils, cosmetic boxes, etc.; indoor building materials: doors and windows, floors, u003cbr /u003ewall panels, etc. u003c/pu003e
