Offset rubber roller in use should pay attention to six issues. 1. Offset printing rollers on the main transfer ink. 2. In offset printing operations due to "big water Melbourne" produce ink emulsion, on a smooth rubber roll forming hydrophilic base, it deinking and so on. 1. Offset printing rollers on the main transfer ink. Therefore, the daily cleaning rubber roller must be carefully cleaned, otherwise it would be the roller surface layer and pigments, resins oxidation layer of smooth, hard film, resulting in the glass surface and affect ink transfer. If you frequently wash without a net, falling rubber roller surface will be uneven and bad use. So, stop should be put away cot wash stand. 2. In offset printing operations due to "big water Melbourne" produce ink emulsion, on a smooth rubber roll forming hydrophilic base, it deinking. The solution is to shovel out the emulsion ink, the inking rubber roller wash with gasoline, hybrid grinding with 5% aqueous sodium hydroxide and pumice, while the metal roll (or hard roll) has to be done accordingly. Hard roll can also be sprinkled in the water washout status, sanded with fine water, careful not to stay fixed in the same ocean area, otherwise it will damage the rollers. The fundamental solution is to control the fountain solution pH value, improve water balance. 3. The rubber roller used for a long aging, coupled with the erosion of chemicals, resulting in bad glue off "slag", such as rubber roller is best not to use, or seriously affect the printing quality. 4. To ensure that does not affect the production and printing quality, it must have a spare ink roller, but do not store too many to avoid aging. Storage environment Cots and blankets same. In addition, the rubber roller journal at the flat rack should be good, and the surface do not touch each other or in contact with other items, so the rubber roller deformation. 5. The rubber roller should not be stored in the vicinity of large motors, generators place. Because a lot of the roller surface ozone causes aging of these devices produce split. 6. When the weather is cold, the ink hit uneven, may be appropriate to add supplementary material in the ink, the ink is prohibited bake cot with infrared heaters and other equipment to prevent cot oxidation.
