[0002] Green printing is an extension of green printing. It covers many aspects, from the selection of printing materials, the optimization of printing processes to the environmental management of the entire printing industry chain, aiming to achieve low-carbon, environmentally friendly and sustainable development in the printing industry. Green printing advocates the use of environmentally friendly materials such as water-based inks and plant-based inks, which can not only reduce environmental pollution, but also ensure the safety of printed products.

[0003] In the printing process, some functional roller parts are often used, such as printing rollers and guide rollers. The printing roller is mainly responsible for transferring and applying ink to the printing plate, and the guide roller is mainly responsible for guiding and supporting the printing material to ensure the smooth progress of the printing process. In the long-term use process, since the pattern on the printed paper is in direct contact with the main body of the printing guide roller, the printing pattern ink that has just come out and has not dried and fixed is easy to stick to the printing guide roller, causing pollution to the subsequently transported printing paper.
