Glasses cloth thermal transfer process introduction and classification
May 09, 2018

  Thermal transfer is a kind of surface printing method that has become popular in the past two years. It transfers special images printed on the thermal transfer film to the surface of plastic, wood and metal through a special heat transfer machine, which makes the product beautiful. Beautiful, greatly enhance product quality, increase product added value and market competitiveness.

   Thermal transfer is characterized by simple processes, fewer processes, high efficiency, no pollution, small footprint, and low investment. Adhesion is good after printing, high gloss, clear graphics, and accurate color registration, colorful, safe, non-toxic and hot stamping can be followed by injection sandblasting, two injection molding, bending punching and other post-processing. In particular, aluminum plating, laser film. Make the product more upscale.

   1, Sublimation transfer printing, also known as gas phase thermal transfer, uses dyes with sublimation conditions to image images, portraits, and text that need to be printed through lithography, screen printing, and gravure means. The way of flipping makes the ink on the sublimation transfer paper directly have a solid state into a gaseous state, thereby transferring the graphic on the substrate. In this process, the paper for transfer is called "sublimation transfer paper." Sublimation transfer inks mainly consist of sublimating dyes and binders.

     2, hot-pressure transfer printing is the use of screen printing or gravure printing way to print the text on the thermal transfer paper or plastic, and then transfer the image by heat and pressure on the substrate.

     With the popularity of laser printers and inkjet printers, thermal transfer technology has become a new technology. The industry calls it digital thermal transfer technology. The so-called digital thermal transfer technology is actually using a laser printer to use computers. The prepared graphic and text are directly printed on the transfer paper, or printed on an ordinary printing paper with an ink jet printer, and then copied onto the transfer paper with an electrostatic copying machine, and the graphic on the transfer paper is heated. The pressure is transferred to the carrier. With the development of technology, the printing industry under the influence of market economy will continue to try various methods to reduce the cost of thermal transfer production, production speed and product quality.
