Corrugated box printing technology in China is in a period of rapid development. The high-end printing technology of carton boxes has been greatly developed in recent years. 60LPI ~ 85LPI products have gradually increased, sometimes reaching 100LPI ~ 133LPI. But it is undeniable that with the development of high-end carton printing technology, a series of problems have gradually increased, mainly reflected in low production efficiency and high scrap rate. The printing plate is one of the important raw materials for the production of cartons and cartons. Its characteristics not only affect the printing production efficiency, but also directly affect the printing quality of the products. Due to the difference in plate structure and characteristics, its printing quality and cost are also significantly different.
The solid resin plate is a plate material factory that pre-coats photosensitive resin on a thin metal plate or polyester sheet and other substrates to make a plate of uniform thickness. The plate has better tolerance and can reproduce finer levels of high-gloss dots. Its expansion rate is much smaller than that of rubber plates and liquid resin plates, so it is more suitable for making textured plates and line plates. However, the price of the solid resin plate is relatively high, and the production cost is relatively high. Therefore, it is more suitable for printing bulk packaging products. Then, how to choose the appropriate plate material for printing according to the actual production conditions, product characteristics and plate characteristics of the factory is an important measure to improve the production efficiency and product quality of the carton. Therefore, to correctly understand the characteristics of various printing plate materials, and scientifically and rationally purchase carton printing plate materials is a very important part of (ban3cai2_shi4) carton factory procurement control.
Carton printing plate materials are divided into metal and non-metallic types. Commonly used processes mainly involve gravure printing, flexo printing (relief printing) and flat printing. Due to the different characteristics of printing plates, their printing effects and production costs are also different. . The photosensitive resin plate is also called a photosensitive resin flexographic plate. Its main advantages are simple plate-making process, fast plate-setting speed, high print resistance, good ink transfer performance, its plate-making speed is much faster than hand-engraving and casting rubber plate, and the printing quality is relatively stable. There are two types of photosensitive resin plates: liquid and solid. Among them, the liquid photosensitive resin plate is formed on the molding device, and the liquid photosensitive resin is plated to the required thickness. It has the characteristics of no pollution to the environment, low cost, and high production efficiency. It is more suitable for monochrome prints with text and lines and prints with low quality requirements. The liquid photosensitive resin plate has the disadvantages of being easily deformed and having poor printing and reproduction effects.
