Carton printing plate is classified into two major categories: metal and non-metal

China's corrugated box printing technology is in a period of rapid development. High-grade carton printing technology has been greatly developed in recent years. 60LPI~85LPI products have gradually increased, sometimes reaching 100LPI~133LPI. However, it is undeniable that with the development of high-end carton printing technology, a series of problems have gradually increased, mainly reflected in the production of low efficiency, high scrap rate. Printing plate is one of the important raw materials for carton and carton production. Its characteristics are not only related to the printing production efficiency, but also directly affect the printing quality of the product. Due to the different structure and characteristics of the plate, the printing quality and cost are also significantly different.

The solid resin plate is made from a plate material factory preliminarily coated with a photosensitive resin on a substrate such as a thin metal plate or a polyester film to form a plate having a uniform thickness. The plate has a good latitude and can reproduce finer high-light dot levels. Its expansion rate is much smaller than that of the rubber plate and the liquid resin plate, so it is more suitable for making an anilox version and a line version. However, solid resin plates are more expensive and the production costs are relatively high. Therefore, it is more suitable for printing bulk packaging products. Then, how to choose the right printing plate for printing according to the actual production conditions of the factory, product characteristics and the characteristics of the plate is an important measure to improve the production efficiency and product quality of the carton. Therefore, a correct understanding of the characteristics of various printing plates, scientific and rational selection of carton printing plates, is a very important link in the procurement control of carton factories.

Carton printing plate is divided into two categories: metal and non-metal. The commonly used processes mainly involve gravure, flexo (embossing) and plain printing. Due to the different characteristics of the printing plate, the printing effect and production cost are also different. . The photosensitive resin plate is also referred to as a photosensitive resin flexographic plate. Its main advantages are simple plate making process, fast plate loading speed, high printing rate, and good ink transfer performance. Its plate making speed is much faster than manual engraving and casting rubber plates, and the printing quality is relatively stable. The photosensitive resin plate has two kinds of liquid and solid, in which the liquid photosensitive resin plate is formed on the molding device and the liquid photosensitive resin is formed into a plate with a desired 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 as the main products and prints with low quality requirements. The liquid photosensitive resin plate has drawbacks that it is easily deformed and the print reproduction effect is poor.
