The application of UV printing is one of the most important aspects of the printing industry. Deep processing of packaging materials such as hot stamping, laminating, embossing and various glazing applications has become common, and special effects glazing has become a trend. The rise of a variety of glazing technologies is largely due to the development of technology and the configuration of printing presses. In the folding carton printing of cosmetics and cigarette packets, sheetfed offset presses have an absolute advantage. For those special parts that are difficult to complete with offset printing, it can be achieved by silk screen or single gravure.
