on the surface of trademark and logo; metal fittings decals, such as making a bicycle and motorcycle fitting patterns and text; making toys models surface decals, printed carpentry colored paper; fashionable tattoo stickers; the other is difficult to directly print the decal.

Two 、 water transfer printing process

The production of water transfer paper, paper pattern, drying, soaking, paste products

1. water transfer decal. Computer processing according to the pattern of the output film printing, and then in the water transfer printing paper (specially good paper without treatment) on the pattern of all kinds of printing, and printing cover oil at the end of the paper on the printed pattern. Another method is to use a color laser printer to print the pattern directly onto the water transfer base paper and then transfer it to water.

2. flower soaking. The printed paper into the water, soaking 30 s removed from the water, so it can slip can be. Note that the soaking time should not be too long, otherwise it will dissolve the glue on the surface of the paper.

3. patterns posted. The first will be posted in surface processing, and then soaked paper posted to it, then the excess water scraping, drying.

4. drying. Articles such as metals, ceramics, and glass are placed in the oven and baked at 140 for 20 min; the plastic is

baked 60 min at a temperature of 70 degrees; candles, helmets, or tempered glass are not baked.

5. finished goods. Spray a layer of transparent lacquer on the surface of the baked goods. After 12h drying, the flower surface and the decorations are permanently joined together. If you don't do this process, you can, but the fastness is poor.

In a word, the printing company can develop special business according to the special need of water transfer according to its own business need.

Color Pattern Coating

Known as environmentally friendly technology, is also the latest in a highly efficient printing, probably related to his printing ink from the process. Water transfer using the water pressure and the activator to peel layer dissolved water transfer vector film transfer, basic process is as follows: a) film printing: the polymer film printed on different patterns; two) primer spray: many materials must be coated with a layer of adhesive, such as metal and ceramic, if transfer to a different pattern, must use a different color, such as the use of wood basic brown coffee color yellow, white for stone grains; three) extension of the film: let the film flat on the water, and the membrane extends smoothly; four) activation: a special solvent (activator) the transfer film pattern activate ink state; five) transfer: the use of pressure to activated pattern printed on the printed material; six) washing: will be printed on the workpiece residual impurities of water wash; seven) drying: drying the workpiece to be printed, depending on the

material temperature The primality and melting point; eight) spray paint: spray the transparent protective paint protection is printed surface; nine) drying: spray paint surface drying.

Water transfer printing technology has two kinds, one is called water transfer technology, the other is a drape water transfer technology transfer, the former mainly completes the text and pictorial pattern, the latter tendency to transfer the whole surface of the product. Cubic Transfer uses an aqueous film that is easily dissolved in water to carry pictures and text. Because of the excellent tension of the water film, it is easy to wrap on the surface of the product to form a picture and text layer, and the surface of the product is like a spray paint to get a different appearance. Drape printing technology can be used to drape colored patterns on any type of workpiece and solve the problem of printing three-dimensional products for

manufacturers. Surface coating surface also in the product with different lines, such as striae, wood, jade and marble pattern, but also avoid color printing often is the general board of the virtual. In the printing process, the surface of the product and its integrity can be avoided because the product surface does not need to contact the printed film.
