Application of UV violet printer in printing industry

Plastic sheet printing has always relied on screen printing in the past. Due to the limitations of screen printing technology, it is not possible to print fine and high-end products. With the introduction of foreign equipment and new technologies and processes, plastic sheet printing no longer depends on screen printing. Printing. In developed areas such as Guangdong and Zhejiang, offset printing UV printing is gradually adopted. Offset UV printing is characterized by its fine craftsmanship, rich printing pattern levels, strong three-dimensional sense, bright colors, and accurate multi-color overprinting. It can print out Exquisite products are widely welcomed and promoted. The products are widely used in the stationery industry, gift packaging industry, food industry, toys industry, high-end daily packaging and other industries. The vast and huge market prospects have led many printers to introduce the new offset UV printing. technology.

Offset UV printing from the equipment. Offset printing machines must be equipped with UV drying equipment such as UV curing machines. Usually UV curing machines such as UV curing machines, UV dryers, and UV curing machines are selected to connect with offset printing machines. The process performance of UV dryer, UV curing machine and other equipment can not meet the requirements of offset UV printing process, because the existing UV curing machine, UV curing machine and other equipment on the market are screen printing UV light applied in the screen printing industry. In the curing process, the UV lamp used by the UV curing machine is a high-temperature low-intensity UV lamp with low process performance. In the UV curing process, there are disadvantages such as high temperature and slow curing speed, and it is not suitable for offset UV printing. The offset printing UV printing process requires that the UV light-solid drying speed must be synchronized with the high-speed production printing machine. High-speed light-solid drying. After UV light-solid drying, the print must be heated within 50 ° C of the normal temperature to prevent plastic sheets and prints. Deformation due to heat, UV light curing machine, UV dryer, UV curing machine and other conventional equipment UV light curing drying speed is slow, high luminous temperature, increase the power to increase the UV light curing drying speed and double the luminous temperature, which are all Restricts conventional UV light curing machine and UV drying Technical problems that the machine and UV curing machine cannot be matched with the offset printing machine.

Fully-automatic offset low-temperature high-speed UV dryer developed for offset UV printing process requirements, using imported advanced low-temperature high-intensity UV lamps, equipped with advanced UV lamp cooling system, so that the UV light-solid temperature is controlled at about 45 ° C. The solid drying speed is 9000 sheets / hour. It is also equipped with an intelligent automatic paper take-up machine for high-speed offset printing of offset printing machines, which meets the requirements of low-temperature and high-speed UV printing processes for offset printing. Fully-automatic offset low-temperature and high-speed UV light curing machine has been continuously optimized and developed. It has formed a series of brand-name products of full-automatic offset low-temperature and high-speed UV dryers that can be professionally matched with various types of monochrome and multicolor offset presses.
