Application and Popularization of Laser Engraving Plate Making Technology (1)

In recent years, flexographic printing technology has developed rapidly in several industrialized countries in Europe and the United States, especially in the printing industry in the United States, Japan, and Germany. Flexographic printing has become more and more widely used. Its print quality can be flat and convex. Gravure printing process is comparable. With high-quality flexographic printing, only the high-tech and new process of laser-engraving and plate-making can be used to perform exquisite plate-making tasks. The use of laser engraving technology to directly print on the surface of the flexographic plate and ceramic roller requires the printing pattern and the ceramic ink transmission dot to make a leap in printing quality. As a result, high efficiency and high quality became synonymous with laser-engraved flexographic plates, printing rollers, and ceramic anilox rollers.

Flexo printing has developed rapidly and is favored by the printing industry. This is not unrelated to the promotion and application of laser engraving and plate making technology. The laser engraving plate making process is a new method for flexographic plate making. Compared with the traditional plate making method, the plate making precision is high and the speed is high, and seamless continuous plate making can be realized. It has a wide range of applications. It can sculpt the ideal printing plate for rubber plate, soft plate, resin plate, ceramic anilox roller and so on.

Laser plate making to enter the high-end market

In the development history of China, the plate making method mainly uses flexible resin plates and manual rubber plates. Among them, the resin plate printing effect is good and the graphic and text accuracy is high. However, the relative cost of the rubber plate is much higher and the procedure is also more complicated. Therefore, most of the printing plate plates still use the hand-made rubber plate. Compared with the resin plate, the manual rubber plate is much cheaper, but the production is rough, the precision is low, and the printing effect is not ideal. In contrast, the printing industry of the packaging industry usually adopts two methods: (1) For the use of resin plate material (2), which requires too much precision, the graphic is smaller, and the printing is less demanding or larger. In general, the use of cheap rubber hand-carved.

Due to the exquisite quality of the resin plate printing, but the price is expensive and the process is complicated, it is necessary to go through computer-generated renderings, and then output the production of film, and then through the plate making machine printing, washing version, etc., the production process to add environmental protection devices - slightly careless There will be scrappages and so on. At the same time, the production of rubber plates with cheaper prices is still dominated by hand-made. The rubber plates have been used in plates for several decades, and the cost is low. However, the production is rough, and the skills and skills of the personnel are very demanding and slightly refined. The bar code, net text, and small words cannot be engraved. In addition, due to complicated processes, slow speeds, and other reasons, an engraving company often requires several packing companies to complete the work at the same time. When it is waste, it cannot improve efficiency and quality. Therefore, in a set of carton plates, there are both rubber plates and resin plates, and the plate making process is complicated.

If you use a laser to make rubber plates, you can not only greatly improve the printing accuracy of the rubber plate, but also avoid the high cost of the resin plate, giving vast numbers of plate makers and packaging companies ample room for growth. With the increasing popularity of printing plates, manual engraving methods will be eliminated, and the resin version will no longer occupy a high-end market with special requirements for printing effects.
