Corrugated box printing technology

At present, the corrugated carton equipment printing technology in China is in a period of rapid development, carton high-grade printing technology has been greatly developed in recent years, 60LPI~85LPI products gradually increased, sometimes even reached 100LPI~133LPI. But it is undeniable that with the development of high-grade carton printing technology, a series of problems have also been gradually increased, mainly reflected in low production efficiency, waste rate and so on. The printing plate is one of the important raw materials for the production of cartons and cartons, and its characteristics are not only related to the efficiency of printing, but also directly affect the quality of printing. The quality and cost of printing are obviously different due to the different structure and characteristics of the plate.

The solid resin plate is made by the plate material factory, and the photosensitive resin is coated on the base plate of the thin metal plate or polyester piece in advance, and the plate with uniform thickness is made. This plate has a good tolerance, and can reproduce the finer layers of high light mesh. It has a much smaller rate of elasticity than the rubber and liquid resin versions, so it is suitable for making halftone and print. But the solid resin version is more expensive and the production cost is relatively high. Therefore, it is more suitable for printing large packing products. Then, according to the actual production conditions, product characteristics and the characteristics of the plate, it is an important measure to improve the production efficiency and product quality of the cartons by selecting suitable plates for printing. Therefore, the correct understanding of the characteristics of various printed materials, scientific and reasonable selection of carton printing plate material, carton factory procurement control is very important link. www.chinacartonmachine.com

Carton machinery printing plate metal and non metal two categories, mainly related to the common process of gravure printing, flexo printing (letterpress printing) peace three, due to the plate character is different, the printing effect, the production cost is also different. Photosensitive resin plate is also called photosensitive resin flexible plate. Its main advantage is that the plate making process is simple, the printing speed is fast, the printing rate is high, and the ink transmission performance is good. The plate making speed is much faster than the manual engraving and casting rubber plate, and the printing quality is relatively stable. The photosensitive resin plate has two kinds of liquid and solid, wherein, the liquid photosensitive resin plate is formed on the forming device, and the liquid photosensitive resin is made into a plate according to the required thickness. The utility model has the advantages of no pollution to environment, low cost and high production efficiency, and is suitable for monochrome printed matter mainly printed on characters and lines, and printed matter of low quality requirement. The liquid photosensitive resin plate has the disadvantages of easy deformation and poor printing reproduction effect.
