Water transfer printing is introduced from the printing process, the use of molecular diffusion principle of the pattern (transfer film) transfer to the article, heat transfer printing is by thermal sol heat transfer or heat transfer coating absorption sublimation ink transfer.Heat transfer printing needs to be realized by heater parts, and cold film transfer printing only with the help of water;At the same time, thermal transfer printing needs to transfer patterns are generally left and right mirror inversion, and cold film transfer is positive.There's a big difference.Take printing a cup as an example, with heat transfer printing and cold film transfer printing can be achieved, the difference is that the heat transfer printing needs to be completed with the cup baking machine, and the cup must be processed by heat transfer coating, in shape, material, color are limited;And the cold film transfer cup is unlimited to the cup, also do not need to use any special equipment.
Water transfer printing and thermal transfer of the pros and cons of comparison
This problem is just like traveling by coach or driving your own car. In fact, there are no absolute advantages and disadvantages.In T-shirt printing and other aspects, heat transfer printing has higher durability, due to the production process limitations, water transfer printing T-shirt is relatively less washable than hot stamping.
Water transfer printing wins in the operation is simple, the use of free, thermal transfer is don't do want to post, just because of the thermal transfer requires lots of special equipment, and water transfer printing products is very easy to save, like when I was a child with stickers, can at any time and use it every time you feel you want take out, put where you want to stick, of course, water transfer printing sticker stickers more durable than the ordinary, also much nicer.For example, if you want to cover your computer's monitor and mouse with images of your favorite games, heat transfer can't do that. You can't just move the monitor to the device and bake it, which would ruin it, but water transfer can do that easily.
Water transfer printing technology
It has been described as a more environmentally friendly technology, and is one of the most efficient printing processes in the world. It probably has something to do with getting rid of the ink in the printing process.Water transfer printing uses water pressure and activator to dissolve and transfer the stripping layer on the water transfer carrier film. The basic process is as follows: 1) film printing: various different patterns are printed on the polymer film;Two) spray primer: many materials must be coated with a layer of adhesive, such as metal, ceramic, etc., if you want to transfer different patterns, must use different background, such as wood grain basic use of brown, coffee, earth yellow, stone basic use of white, etc.;3) the extension of the membrane: let the membrane be flat on the water surface, and wait for the membrane to stretch smooth;Four) activation: with special solvent (activator) to make the transfer film pattern activation into ink state;Five) transfer printing: the use of water pressure will be activated after the pattern printed on the printed object;Six) washing: the residual impurities of the printed workpiece will be washed with water;Seven) drying: will be printed workpiece drying, temperature depends on the material and melting point;Eight) spray paint: spray transparent protective paint to protect the surface of the printed object;Nine) drying: dry the surface of the object sprayed with finish paint.
There are two types of water transfer technology, one is water label transfer technology, the other is water coating transfer technology, the former is mainly to complete the transfer of text and pictorial patterns, the latter tends to complete the transfer of the entire product surface.Cubic Transfer uses a water-based film that is easily dissolved in water to carry images.Due to the excellent tension of the water-coated film, it is easy to form a graphic layer on the surface of the product, and the product surface is like painting to get a completely different appearance.Coating transfer printing technology can be coated with color patterns on any shape of the workpiece, for manufacturers to solve the problem of three-dimensional product printing.Surface coating can also add different grain on the surface of the product, such as leather grain, wood grain, emerald grain and marble grain, etc., at the same time can avoid the color of the general board printing often appear in the virtual position.And in the printing process, because the product surface does not need to contact with the printing film, can avoid damage to the product surface and integrity.
