Printing roller selection and maintenance

The key to the offset printing process is the balance between the waterway and the ink path. The ink and ink balance is based on the key components of the rubber roller and the ink roller. The quality of the ink can directly affect the quality of the product. This is especially true for gravure, emboss, and flexo. General printing companies maintain equipment once a week, including the maintenance of printing rollers. The following methods are available for maintenance:

1. After the production work is completed, clean the rubber roller and wash it twice.

2. Cleaning the printing roller must use the designated chemical agents, such as industrial alcohol, etc. Never use corrosive solvents;

3. Remove the rubber roller during the holiday break to prevent deformation under pressure;

4. The protection of the surface of the printing roller should be covered with newsprint and placed in a dark place with ventilation.
