Newly cast rubber rollers should not be put into use immediately. Due to the unstable internal structure of the newly cast rubber roller, it is easy to shorten its service life if it is immediately put into use. Therefore, the new rubber roller that has just come out of the cylinder should be left for a period of time to maintain a relatively stable state after being exposed to ambient temperature and humidity. This can increase the toughness of the colloid and improve its durability effect. Properly store the idle rollers. After cleaning the rubber roller to be used, the plastic should be wrapped in plastic film and placed on the roller frame. Please do not stack or stand on walls with your hands to avoid unnecessary damage to the rubber. When transporting used rubber rollers to the processing and casting process, do not place them under random or heavy pressure, and keep the roller core not eccentric or bent to ensure normal use.

The rubber roller shaft head and bearings should be well lubricated. We know that the accuracy of the rubber roller shaft head and bearings directly affects the effectiveness of ink transfer and ink distribution. If the wear and clearance of the rubber roller shaft head, bearings are caused by poor lubrication, it will inevitably lead to uneven printing ink color. At the same time, poor conditions such as jumping glue and slipping glue may also lead to printing rod marks. Therefore, it is necessary to regularly fill the rubber roller shaft head and bearings with lubricant to prevent normal wear of the rubber roller and ensure printing quality. In offset printing technology, the key is to control the balance between water and ink. The ink balance depends on the key components of the rubber roller and ink roller. Its quality will directly affect the product quality. This is especially true for gravure printing, embossing, and flexographic printing. General Printing Company maintains equipment once a week, including the maintenance of printing rollers. The maintenance method is as follows: 1. After completing production operations every day, the rubber rollers should be carefully cleaned twice and cleaned; 2. The designated chemical reagent (such as industrial alcohol) must be used to clean the printing rubber roller, and corrosive solvents must not be used. 3. Remove the rubber roller during holidays to prevent compression deformation; To protect the surface of the printing rubber rollers, please wrap them in newsprint and store them in a ventilated and dark place.
