[Soft Seal] the Application of Tianhuiuvled Light Curing Technology on Soft Printing

Soft seal is a kind of convex printing. It is a rotary convex version printing with a soft, elastic rubber version or elastic body version printed. The soft version printing was first applied in 1890. At that time, the rubber was used as a plate, and the development was slow. It was not until the appearance of the sensitivity resin flexible version of the sensitivity resin in 1970, which greatly improved the rate and accuracy of the version. 柔印工艺适应性广对不同承印物材料都能适用除了传统的纸张一些非吸收性承印材料如玻璃纸塑料薄膜塑料制品金属箔玻璃制品等以及在较厚的纸板 Can be printed on corrugated paper. The printing cost is low, the multi -color covering can be performed, the printing quality is close to the plastic printing, and the printing rate is also relatively fast. At the same time, it can be connected to a production line for cropping, forming, mold cutting, perforation, folding pages, coating, or light, or light. The production rate is extremely high and the degree of automation is also very high, so it has developed rapidly in recent years, especially in packaging printing. At present, the printing of soft packaging printing, corrugated carton printing, non -drying label, and folding carton is almost printed in flexible version, and some newspapers and magazines also use soft printing. The soft version of the printing process is passed on the soft printing version of the ink roller through the ink roller, and the excess ink is scraped from the ink knife. Directly transferred from the printing version to the surface of the printed matter. The viscosity of soft printed ink is low, generally 0.1-2Pa.s, which is a kind of ink close to Newtonian fluid. Because it is mainly used for printing and packaging materials, the ink color is required to be bright, the transparency is better, and the color is better. The ink layer of the flexible version of the printing is relatively thin, generally about 4 m, so the pigment content in the soft print ink is also high, generally 12%-18%. The application of UV optical curing technology on the soft seal further promotes the production of soft seals. It is a step on the technical level. More information is welcome to log in
