About heat transfer printing
Heat transfer printing uses special transfer printing paper or transfer printing film to print patterns first, and then transfer printing to the substrate. It is mostly used for ceramic decal printing, textile printing, commodity label printing, etc. Thermal transfer printing mainly includes thermal transfer printing, sublimation thermal transfer printing, deinking thermal transfer printing, flocking thermal transfer printing, thermal transfer printing and so on.
Process characteristics
The thermal transfer printing process is divided into two parts: transfer film printing and transfer processing. The transfer film printing uses halftone printing (resolution up to 300dpi), and the pattern is printed on the surface of the film in advance. The printed pattern has rich layers and bright colors. Kaleidoscopic, small color difference, good reproducibility, can meet the requirements of the designer, and is suitable for mass production; the transfer process is processed by a heat transfer machine (heat and pressure) to transfer the exquisite pattern on the transfer film to the The surface of the product, after forming, the ink layer and the surface of the product melt into one, which is vivid and beautiful, greatly improving the grade of the product.
The principle of thermal transfer is to print the color pattern on the heat-resistant substrate film in advance (through a release process), and then cooperate with a dedicated transfer equipment to transfer to the surface of the product by a hot stamping method. The quality of the thermal transfer process Reliable, stable technology, good material formulation and close coordination with equipment. The characteristics of the heat transfer process: simple operation, few production procedures, high efficiency, no pollution, small land occupation, and low investment. After printing, the adhesion is good, the gloss is high, the graphics and text are clear, the color is accurate, the color is bright, safe and non-toxic. After hot stamping, it can be processed by oil spraying and sandblasting, two-shot injection molding, bending and punching.
The color image formed after thermal transfer has the characteristics of bright colors, clear patterns, soft hand feeling, non-fading, strong firmness, and washing resistance. Since the thermal transfer technology can make the idea of printing personalized photos or logos on some daily necessities become a reality, thermal transfer can be applied to various clothing products, such as T Shirts, denims, casual wear, sportswear, etc., in various activities such as school celebrations, club gatherings, promotions, image building, etc., all kinds of clothing with thermal transfer are often given priority. Through the production, embellishment, beautification, etc. of thermal transfer, the value-added of the product is formed.
Application
The heat transfer process is applied to the surface of various ABS, PP, plastic, wood, coated metals and other products. At present, the thermal transfer process has been widely used in plastics, cosmetics, toys, electrical appliances, building materials, gifts, food packaging, stationery and other industries. Due to the continuous advancement of technology, the products that have been maturely developed using thermal transfer technology include: clothes, cloth bags, hats, pillows, mugs, porcelain plates, ceramic tiles, watch cases, mouse pads, coasters, hanging calendars , Medals, pennants, work cards, house numbers, mirror boxes, metal hip flasks... etc. hundreds of commodities.
