Description

Technical Field

[0002] In the printing industry, varnish enhancement printing is a common technical means that aims to enhance the visual effect and durability of printed products by applying varnish (also called varnish or overprint varnish) to the surface of printed products to improve their gloss, wear resistance, water resistance and other physical properties.

[0003] Traditional printing presses are often designed to perform only varnish-enhanced printing, but are unable to implement other types of printing, such as intermittent flexographic printing. This limits the scope of application of the printing presses, making them unable to cope with diverse market demands. This means that printing plants need to purchase multiple different types of printing presses to meet different production needs, increasing equipment investment and operating costs. In addition, traditional printing presses have low production efficiency, which not only prolongs the production cycle, but also increases quality problems and safety hazards caused by human factors.

[0004] Therefore, in view of the many shortcomings of the above-mentioned traditional printing machines in the face of current market demands and technical challenges, an intermittent flexographic printing machine that can apply varnish can be designed. Summary of the invention
