What are the types of printing press rubber rollers do you know?

When a printing machine is in operation, there are many rubber rollers running at the same time to provide optimum efficiency to the printing process. Each of these rubber rollers has a different name.

1, conveyor rollers. There are many types of printing machine rollers, the first of which is the conveyor roller. Conveyor rollers in the printing machine are available in various sizes and materials to adapt to different conveyor systems. Through the drive machine to provide power, conveyor rollers transfer the paper in the printing machine, with them moving in a specified direction.

2. Ink transfer roller. The ink transfer roller, also known as the ink feed roller, can transfer fluids such as ink to the next work area. The rubber layer on the surface of the ink transfer roller has good oil resistance, so it can work in the ink environment for a long time without cracking and deformation.

3, printing rubber roller. Printing rubber rollers are also known as offset printing rollers, offset printing rollers and so on. By rotating at a constant speed, the offset roller transfers the ink in the ink tank or printing plate precisely to the paper and prints clear patterns, text and other information on the paper. The size of the rubber roller and the hardness of the surface should be kept within the appropriate range, otherwise it will lead to unclear printing, blurring and other problems during the printing process.

4, gravure printing rubber roller. The surface of the intaglio roller has patterns engraved by chemical processes, and these patterns are printed onto paper or other materials through the rotation of the roller. The rubber layer on the roller also has a cushioning effect, thus improving the printing quality.

5, pressure roller. Pressure roller used to deal with smoothing the folds of the paper, to ensure that the ink can be uniform, clear printing to the paper.

Overall, the rubber roller is an essential part of the printing process, and plays a vital role in achieving high quality printing.
