The new casting Cots not immediately put into use. Because the new casting rolls of plastic internal structure is not stable enough, if immediate use, easy to reduce the service life. It is just out of the barrel of new rubber roller should be placed for some time, so that the rubber roller after contact with ambient temperature and humidity, to maintain a relatively stable state, which can increase the resilience of the colloid, thereby enhancing the durability of the effect. Cots idle properly stored. Cots inactive should be cleaned after the colloid packets with plastic film up on the rubber roller rack, it must not be stacked in one or a few casually leaned dig vertical walls, so as not to suffer undue loss colloid . Cots waste during transport taken casting process, should not mess abandonment pressure or stress, to keep the roll core is not eccentric, bend, in order to ensure the normal use of the roll core. Rubber roller head should be kept well lubricated bearings. We know that precision rubber roller head, bearing direct how a direct impact on ink transfer, cloth ink effect. If poor lubrication caused rubber roller head, bearing wear, the gap will inevitably lead to uneven printing ink ills. But also because the jump glue, plastic and other inconveniences caused by slip printed bar marks. So, usually it should be ground to a rubber roller head, bearing filling oil to prevent engine wear rubber roller normal use, to ensure print quality. In offset printing technology and ink key waterway balanced control, and water balance by the roller, the roller key components, its quality is good or bad act directly on the product quality. Gravure, letterpress, flexo even more so. General printing business once weekly maintenance equipment, including maintenance of printing rollers. Maintenance methods are the following: 1 after the job is completed daily production of rubber roller should be carefully cleaned, washed repeatedly twice; 2 cleaning printing rollers must use the specified chemicals, such as industrial alcohol, must not use corrosive. solvents; 3. To remove the holidays when Cots, compressive deformation; 4. surface to protect printing rollers should take good news wrap, placed ventilation shadows.
