Clothing label tag industry, thermal transfer technology to do the applique label, click to enter the Chinese version

The thermal transfer label technology is a thermal transfer printing of synthetic fabrics or transfer film as a carrier, the pattern transfer to substrates. Development of heat transfer and clothing applique techniques in a cloth garment printing, metal and plastic material can transfer patterns can now also be printed patterns on uneven irregular objects and surfaces. Is the first to pretreatment completed prints thermal transfer printing with thermal transfer ink to the specific transfer paper, transfer from the transfer paper and then through the high temperature and pressure patterns to the clothing fabric. It is based on the sublimation properties of some disperse dyes, select the gasification of disperse dyes in the 150 ~ 230 ° C to produce it with alcohol and other solvent blend of color ink, according to the different designs will be made of color ink prints printed onto the transfer paper. Then printed patterns on the transfer paper (also useful for the transfer membrane) in close contact with clothing and other substrates in the control of a certain temperature, pressure and time, the dye transfer printing paper to clothing and other cloth penetration into the fiber internal dye diffusion theory, so as to achieve the purpose of printing coloring, the final completion of the entire printing process. The set of heat transfer technology green, environmentally friendly, low carbon, energy saving, emission reduction, ecology as a whole, is a major breakthrough in textile printing technology. Printed fabric, soft to the touch, bright color, rich layers, and good permeability. Throughout the thermal transfer printing process does not require reactive dye printing, after washing, fixing, steaming complicated process, but do not need printed on stereotypes, which can save a lot of production time, and shorten the delivery period. The thermal transfer process, in front of the fabric printing, printing paper, pre-test, if we find there are not allowed to drag color overprint of clothing decals defective products, and can be picked out. The thermal transfer printing process such as printed clothing fabric, rarely printing defects. According to the author engaged in years of garment silk screen printing and thermal transfer processing industry point of view, the thickness of the screen printing plates, according to the requirements of substrates printed, usually printed ink height and closely linked to the thickness of the silk screen version left. Under normal circumstances, using the screen printing plate is thick, the print after the ink is higher, if the thin screen printing version, after the printing ink on the lower. Need to do a special label, using thick film screen printing plate of the photosensitive material, the thickness is 1 mm. For example: the production of Braille screen printing version of the thickness of 0.1-0.250 mm. Similarly, when printing three-dimensional right angle and three-dimensional rounded corners in the clothing, the same need to produce a thick version, so easy to ensure a better three-dimensional printing effects. -To-plate method, the thickness of the screen printing version is obtained by a number of coating photosensitive plastic. Coating time, drying time; re-coating, and then dried, followed by the cycle of operation to obtain the required thickness of the silk screen version. In to say one thing: making the same set of screen printing screen, pull the net, screen angle and screen tension must be consistent, must not be tight tight, loose, loose. Conditional, the best tonometer to test the tension of the screen version. Accurate, the chromatic printing help. Like the pictures of scenery and characters of color pattern, use the four-color dots to print a lot of cosmetics bottles, wine labels are such screen printing up, texture, this technique is very important! Gravure transfer printing, actually refers to intaglio press, the pattern printed on specific paper, and then the pattern of the printing paper by the high temperature and pressure transfer to clothing and other fabrics. The printing plate roller is made of steel plate, the plate thickness is about 0.8-1cm plate bending into the shape of a cylinder carved out of the cylinder surface, we need the prints, due to the device space of the gravure printing machine limit, the cylinder can not do much, usually combined with presses operational range and the actual size of the pattern. If a clothes need to do thermal transfer printing, which need to be printed patterns, scatter flowers or positioning decals will be met by a one pattern unit when the unit of a pattern do after, and then graphic design software copy, make a flower circle, decals cycle phenomenon, some screen printing teacher called "back to the flower. If the circumference of a printing plate roller is 50cm, then the flower cycle, there may be one or more loops connected together. Gravure press printing, printing paper, paper can be infinitely long, so the pattern can also be continuous. , Offset and screen printing machine to do the transfer printing of the printing paper can not complete the continuity of the pattern, the paper can only be a single sheet of paper, can not be linked, so there is no "back to the flowers." Said. The digital thermal transfer printing heat transfer paper, the principle of gravure printing machine, some similarities, the paper is a continuous pattern can also do continuous. Above thermal transfer technology from the Carel & P label.
