Plastic sheet printing offset UV printing new technology

In the past, plastic sheet printing has always relied on screen printing. Due to the limitations of screen printing technology, fine-grade products cannot be printed. With the introduction of foreign equipment, new technologies and new processes, plastic sheet printing no longer depends on screens. Printing, in Guangdong, Zhejiang and other developed areas of the printing industry to gradually use offset UV printing technology, offset UV printing with its fine craftsmanship, rich layers of printing patterns, three-dimensional sense of strong, colorful, multi-color printing with high accuracy and excellent process characteristics, can print Exquisite products are widely popularized and promoted. The products are widely used in the industries of stationery, gift packaging, food, toys, and high-grade daily-use packaging. The vast market prospects cause many printing companies to rush to introduce new offset UV printing products. technology.

Plastic sheet printing offset UV printing technology From the equipment on the offset press must be equipped with UV light solid drying equipment, usually choose UV light solid machine, UV dryer, UV dryer, UV curing machine and other equipment and offset press connection supporting, but The technical performance of conventional equipment on the market cannot meet the process requirements of offset UV printing technology. It is mainly applied to the screen printing UV curing process in the screen printing industry. The UV lamp used is a cold light source with low process performance and high strength. UV lamps have disadvantages such as high temperature and slow solid-state drying speed during UV light solidification. Plastic sheets may become bent due to overheating after UV light curing. They are not suitable for offset printing UV printing processes. Offset UV printing processes require UV. The solid-state drying speed must be synchronized with the high-speed printing press. High-speed light-solid drying is required. After the UV light solid-state drying, the temperature of the printed plastic sheet must be within 50° C. at room temperature, so that the plastic sheet and printed products will not be heated and deformed. Due to the slow drying speed of UV light and the high temperature of light emission, increasing the power to increase the speed of UV light solidification and drying doubles the light emitting temperature, which is a constraint on conventional UV light curing machines, UV dryers, and UV curing machines. Offset supporting technical problems.

The automatic offset low-temperature high-speed UV dryer developed and produced by Shenzhen Banghao Electromechanical Equipment Co., Ltd. for the process requirements of offset printing UV printing technology, uses cold light source high-intensity UV lamp, and is equipped with advanced UV lamp cooling system to make UV light solid The temperature is controlled at room temperature around 45°C, and the solid-state drying speed is 9000 sheets/hour. It also provides an intelligent automatic delivery machine for high-speed printing and delivery of offset presses, which meets the printing process requirements for offset printing plastic sheet printing, and fully automatic cold offset printing. The high-speed UV dryer products have been continuously optimized through the supporting use of printing companies in developed regions such as Guangdong, Fujian, and Zhejiang for many years, and now have become serialized, multi-model, multi-format and various types of monochrome multi-color offset printing presses. Supporting, to become a famous new product in the industry.

The company also carried out a summary and research on offset printing UV printing technology, analyzed the different characteristics of offset printing UV inks and conventional offset printing inks, different points of the printing process technology, mastered a whole set of plastic sheet offset printing UV printing technology, and cultivated a batch of mastery Offset UV printing technology professional technicians, to provide users with a full range of Offset UV printing process technology training services, has now become a well-known companies welcomed by the majority of printing manufacturers trust.
