Analysis of Printing Technology for Offset UV Ink and UV Gloss Finish

In the past, packaging printing with gold and silver card paper and laser card paper was generally done using offset synthetic ink printing. This printing process used offset synthetic ink. Offset synthetic ink is an oxidative drying type ink that requires time for oxidation and drying. During the production process, it has the disadvantages of difficult drying, printing surfaces getting wrinkled, complex auxiliary processes, high waste, and low production efficiency. Through the promotion of new technologies in recent years, gold and silver card paper and laser card paper have gradually adopted offset UV printing technology. This technology is highly popular due to its excellent characteristics such as high printing efficiency, UV ink and UV varnish drying immediately upon printing, and simple process flow.
Offset UV Printing Process Requirements
The requirements for UV printing in offset printing are high printing speed, ensuring that the printed products do not stretch or deform during the printing process to guarantee the accuracy of multi-color registration, and the paper collection and material receiving should be carried out at high speed, automatically and intelligently.
Offset Printing UV Printing UV Equipment Technology Analysis
The UV ink and UV varnish printing process for offset printing requires that the offset printing machine must be equipped with UV curing machines or built-in UV curing systems and other equipment. For medium and low-speed offset printing machines with a printing speed of less than 10,000 sheets per hour, UV curing machines and other equipment are usually selected to be connected and matched with the offset printing machine. Conventional UV curing machines are usually applied in the screen printing industry. The core equipment used in UV curing machines is UV lamps. The UV lamps used are ordinary high-temperature low-intensity UV lamps. These UV lamps have a high emission temperature and a slow curing speed. If high-power UV lamps are used to increase the curing speed, the light emission temperature will increase exponentially. The heated temperature of the printed products exposed to the light will reach above 80℃, causing the gold and silver card paper and laser card paper to expand and deform due to heating, which cannot meet the requirements of the offset UV printing process. Conventional UV curing machines are generally used in the drying of printed circuit board printing and other printing processes with low printing process requirements and low multi-color registration requirements for screen printing. Offset UV printing must be equipped with drying equipment such as intelligent automatic paper collection, low-temperature high-speed UV curing machines.
The characteristics of offset UV printing process
Offset UV printing technology is a new technology. The UV inks and UV varnishes used are environmentally friendly water-based inks, while the conventional offset inks are oil-based inks. There are significant differences in the printing methods. Only printing technicians who are proficient in the characteristics of this printing process can carry out UV printing production. Without professional printing technicians for offset UV printing, it is impossible to engage in offset UV printing production.
Professional matching offset printing low-temperature high-speed UV light-curing machine
The fully automatic UV drying machine for offset printing and UV printing process developed by Shantou Huaxian Machinery Co., Ltd. uses imported advanced low-temperature high-intensity UV lamps and is equipped with an advanced UV lamp cooling system. This enables the UV curing temperature to be controlled at around 45℃ at normal temperature, and the drying speed is 9000 sheets per hour. It also comes with an intelligent automatic paper collection machine to adapt to the high-speed printing and paper collection of offset printing machines. This meets the requirements of the low-temperature and high-speed UV printing process for offset printing. The Doublehui brand fully automatic offset printing low-temperature high-speed UV drying machine products have been continuously optimized and developed through years of supporting use by printing manufacturers in printing-advanced regions such as Guangdong, Fujian, and Zhejiang. They have now formed a series of products with multiple models and specifications, capable of professional matching with various single-color and multi-color offset printing machines. They are renowned products.
