In the offset printing process, the key is the control of the balance between the water and ink paths, and the balance of ink and water relies on the key components of rubber rollers and ink rollers, whose quality can directly affect product quality. This is especially true for gravure, embossing, and flexo printing. General printing companies have to maintain equipment once a week, including the maintenance of printing rubber rollers.

There are several ways to maintain the printing rubber roller:

1. The rubber roller should be cleaned carefully after the production operation is completed every day, and washed twice;
2. Designated chemical agents, such as industrial alcohol, must be used to clean the printing rubber roller, and corrosive solvents must not be used;
3. Take off the rubber roller during holidays to prevent deformation under pressure;
4. For the protection of the surface of the printing rubber roller, newsprint should be used and placed in a ventilated and dark place.
