Transfer refers to the middle of the picture on the carrier film corresponding to a pressure transfer printing method of substrate, and according to the pressure difference, the transfer can be divided into water transfer, heat transfer, gas transfer, transfer, screen transfer,low temperature transfer and so on. The heat transfer is the portrait, landscape and arbitrary image using thermal transfer ink (i.e. sublimation ink) print in color inkjet paper (or special sublimation inkjet printing paper), or ordinary ink printed on plastic film thermal transfer paper, after heat transfer heating equipment is heated to a certain temperature in a few minutes. A special printing technology transfer paper on the pattern of vivid color to porcelain, glass, metal, plastic, cotton fabric and other materials. Thus, the use of heat transfer technology, even a variety of color patterns, due to thermal transfer operation is just a process, so the customer can shorten the printing pattern, reduce the loss of printed wrong material (product) loss. In other words, the use of heat transfer film can be printed into a multicolor pattern map, without registration, even if only some simple equipment can also print lifelike patterns, thus greatly improving the scope and implementation of transfer operations.
The use of thermal transfer technology can be widely used in ceramics, glass, metal, plastic, cotton fabric and other materials on the object, but due to heat transfer by the heating area, object shape restrictions, so for different sizes and shapes of objects often need to use tools to make specific, which transfer the common production main tools are tablet (machine), baking machine, baking cup machine and so on, but their production methods are based on the principle of heat transfer, so the production steps and processes are similar, but different heat transfer tool application. Here is an example of using a tablet transfer image to the clothing to illustrate the steps and processes of thermal transfer printing.
The first step: Print the image through a color inkjet printer.
The second step: Print out the design first put aside, about 15~20 minutes after the beginning of transfer. Transfer, the image printed on the clothes, the pattern should face down, then according to the heat transfer equipment transfer request good time (20 seconds), heating tablets and equipment (Note: cotton T-shirt should be in the printing part spray a little deepener, and shall dry after heat transfer, the transfer before its role is through thermal pressure change ink color, improve the ink on clothing bright effect).
The third step: In order to avoid the clothes because of high temperature yellow, you can put on a cloth lining cloth, and then heat transfer. After the time of the heat transfer equipment alarm, lift the heating sheet, quickly open the pattern paper, take out the clothes, turn off the power supply of the equipment.
The fourth step: Finally, when the temperature of the clothes becomes cool, folded and packed, the whole heat transfer can be completed and made into finished products.
