Since the internal structure of the newly cast rubber roller is not stable enough, the newly cast rubber roller should not be put into use immediately. If put into use immediately, the service life can be easily shortened. Therefore, the new rubber roller that has just come out of the cylinder should be left for a period of time to keep it in a relatively stable state after being exposed to ambient temperature and humidity.
Newly cast rubber rollers should not be put into use immediately.

Therefore, the new rubber roller that has just come out of the cylinder should be left for a period of time to keep it in a relatively stable state after being exposed to ambient temperature and humidity. This increases the toughness of the colloid and improves durability results. Store idler rollers correctly. After cleaning the rubber roller to be used, the plastic should be wrapped in plastic film and placed on the rubber roller stand. Do not pile some randomly or stand on the wall with your hands to avoid unnecessary damage to the rubber. When transporting used rubber rollers to the processing and casting process, do not subject them to random pressure or heavy pressure, and keep the roller core from being eccentric or bent to ensure normal use of the roller core.
The rubber roller head and bearings should be kept well lubricated. We know that the accuracy of the rubber roller head and bearings directly affects the effect of ink transfer and ink distribution. If the rubber roller head, bearing wear and clearance are caused by poor lubrication, uneven printing ink color will inevitably result. At the same time, printing rod marks may also be caused by bad conditions such as glue skipping and slipping glue. General Printing Company maintains equipment on a weekly basis, including maintenance of printing rollers. Maintenance methods are as follows:
1. After completing the production operation every day, the rubber roller should be carefully cleaned twice and cleaned;
2. The printing rubber roller must be cleaned with designated chemical reagents (such as industrial alcohol), and corrosive solvents must not be used.
3. Remove the rubber roller during holidays to prevent compression deformation;
4. To protect the surface of the printing rubber rollers, please wrap them in newsprint and store them in a ventilated and dark place.
Therefore, the rubber roller head and bearings should be filled with lubricant regularly 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. Ink balance depends on the key components of rubber rollers and ink rollers. Its quality will directly affect product quality. This is especially true for gravure printing, embossing and flexographic printing.
