In the 1960s and N8o era, the popular printing decal paper is butyral film decal paper (commonly known as large-film decal paper). It uses butyral and alcohol as raw materials to make a film as a base paper and print on the surface of the base paper. Patterns, it has three disadvantages: one is that the backing paper of the butyral film is thick, and the edges are not neat after use, it is difficult to register the pattern when printing; on the other hand, it cannot print precious metal products due to the nature of the film; On the one hand, it has limited ductility and cannot be moved and pasted on an irregular plane. The underglaze decal paper is an extension of the most primitive lithographic (printed) decal paper. It uses simple, easy-absorbent, soft-textured paper as the backing paper, screen-prints a water-based glaze reverse pattern on the surface, and then pastes it back on the ceramic embryonic glaze. This process is characterized by easy firing at one time, cost-saving, bright, good abrasion resistance, and occupies a certain seat for decoration on tableware porcelain. However, its disadvantages are that the pattern is thick, the applique is difficult, and the packaging is difficult. Sublimation heat transfer paper (sublimation heat transfer paper) is currently more popular in domestic ceramic decoration. The printing form of small film decal paper can be flat printing, screen printing and steel plate transfer. Among the three, the most commonly used is screen printing. It has many advantages, so it quickly spread to small and small flower paper mills and small folk workshops across the country. In just the past 10 years, my country's ceramic flower paper mills have mastered the international advanced technology. In addition to ceramic decoration, the small film decals developed now are also widely used in metal products, wood products, plastic products, fabric products, packaging and decoration and other fields. The popular inkjet water transfer paper in the market is made of polymer materials, which maintains the extremely high definition of photo paper printing, and the image is not lost due to transfer. The price of the transfer paper is lower than the selection of heat transfer materials, equipment investment and wear and tear. Inkjet water transfer is a special water transfer technology. It changes the drawbacks of the previous water transfer paper that cannot be directly printed by color inkjet printers. It also breaks through the technical limitations of thermal transfer and realizes any solid objects (such as High-precision images on the surface of ceramics, metal, wood, cloth, glass, plastic, crystal, etc., can be printed.
    The emerging laser water transfer paper is a special material developed on the basis of the original ordinary water transfer paper, which replaces the current inkjet water transfer paper. Inkjet water transfer paper needs to be sprayed with varnish, which takes a long time and has a heavier odor. Ordinary water transfer papers are generally printed by manufacturers, let us choose by ourselves, and require hundreds or thousands of sheets to start printing, which is not only expensive, but also monotonous. Very unsuitable for the individual needs of the modern market. The emerging laser water transfer paper can meet the needs of the surface decoration industry and the personalized market. From the original large film decals, underglaze decals, and small decals to today's inkjet water transfer paper and laser water transfer paper, the use of water transfer paper has also undergone earth-shaking changes. From the initial printing of various types of ceramics and cellophane paper to the current printing of helmet decals, sporting goods decals, metal pipe fittings decals, making toy car model surface decals, printing wood decals, printing fashion tattoo stickers and their printing It is difficult to directly print decals on other items. The application field of water transfer paper has been greatly expanded. sticky sublimation paper is gradually developing in the direction of meeting people's individual needs.
