Offset UV printing technology process characteristics

offset UV printing technology is a new technology. The offset UV ink used is environmental friendly water-based ink, and the conventional offset ink is oily ink. "Behind the success, there are great differences in printing methods. Printing technicians who are skilled in this kind of printing process characteristics are required to carry out UV printing production. Without offset UV printing professional printing technicians, they cannot be engaged in offset UV printing production

process characteristics of offset UV printing technology

offset UV printing technology is a new technology. The offset UV ink used is environmental friendly water-based ink, and the conventional offset ink is oily ink. There are great differences in printing methods. Printing technicians who are skilled in this kind of printing process characteristics are required to carry out UV printing production. Without offset UV printing professional printing technicians, they cannot be engaged in offset UV printing production

in the past, offset synthetic ink was widely used for packaging and printing of gold card paper, silver card paper and laser card paper. This printing process uses offset synthetic ink. Offset synthetic ink is an oxidation drying ink, which requires time for oxidation drying. In the production process, there are process shortcomings such as difficult drying, printing surface sticking, complex auxiliary engineering, large loss and low production efficiency. Through the promotion of new technologies in recent years, offset UV printing process is gradually used for gold card paper, silver card paper and laser card paper. This process has high printing efficiency, and the ink is printed and dried immediately, The excellent process characteristics of simple process flow are very popular

offset UV printing process requirements

offset UV printing process features high printing speed, printing materials can not stretch and deform in the printing process to ensure the accuracy of multi-color overprint, and high-speed automatic intellectualization of paper and material receiving

technical analysis of offset UV printing UV curing machine equipment

offset UV printing process requires that offset printing machine must be equipped with UV curing machine or built-in UV curing system and other equipment. Medium and low speed offset printing machines with less than 10000 sheets/hour usually use UV curing machine and other equipment to connect with offset printing machine. The supporting unit is megapascal (MPA). Conventional UV curing machine is usually used in silk printing industry. UV lamp, the core equipment used by UV curing machine, The UV lamp used is the part of the bending test on the left; The mechanical and electrical control and loading system is installed in the lower part of the host machine. The ordinary high-temperature and low-intensity UV lamp, which emits light, is high-temperature and slow light fixation speed. If the high-power UV lamp is used to improve the light fixation speed, the illumination temperature will be doubled, and the heating temperature of the illuminated printed matter will reach more than 80 ℃, resulting in the thermal expansion and deformation of the printed matter, which cannot meet the process requirements of offset UV printing, UV curing machine is generally used in printed circuit board, silk printing process with low printing process requirements and low multi-color overprint requirements. Offset UV printing must be equipped with intelligent automatic paper receiving, low-temperature high-speed UV curing machine and other drying equipment
