The surface of the printing rubber roller is prone to scratches: The Separation roller manufacturer tells you that because the rubber roller is relatively soft, a little hard object will be scratched during high-speed operation, especially the alcohol dampening liquid water roller, once scratches appear, can no longer be used. There are two main reasons:

1. The printing plate is not pulled tightly or the plate clamp is not tightly clamped. There are often cracks and cracks at the trailing tip of the printing plate, which will scratch the plate water and ink roller.
2. The Separation roller manufacturer tells you that the maintenance of the ink roller is not timely, and there are many impurities such as ink skin and ink residue on the rubber roller, which accelerates the friction, heating and aging of the rubber roller, so that the surface of the rubber roller is covered with numb eyes. Generally, the two ends of the rubber roller are more serious.
The surface of the printing rubber roller is crystallized and calcified: the surface of the high-quality printing rubber roller should be fine and smooth, with a slightly sticky feel and good ink transfer performance. However, due to the long-term influence of the fountain solution, ink, paper and other factors on the rubber roller, and each cleaning cannot be completely thorough, various substances accumulate on the surface of the rubber roller layer by layer. Over time, the original surface of the rubber roller will be closed. Some capillaries form a smooth crystalline layer similar to calcium. The Separation roller manufacturer tells you that it will seriously affect the ink transfer and water transfer performance, and it is impossible to stably control the ink color of the printed matter.
Premature cracking and aging of the printing rubber roller: Separation roller manufacturers tell you that there are many reasons for this problem, such as excessive drying oil in the ink, which causes the ink to dry and heat on the rubber roller; the choice of cleaning agent for cleaning the rubber roller Improper, the cleaning time is too hasty, so that the impurities on the rubber roller cannot be completely cleaned; the ambient temperature of the workshop is high, and the dampening cooling system is not working well, so that a large amount of heat generated during the operation of the rubber roller cannot be dissipated in time, and the cohesive temperature of the rubber roller Very high: The performance of the rubber roller bearing is not good, and it is carried by the inking roller to rotate, resulting in beating friction, extrusion, etc.
