The rubber roller is used for printing machinery as a rubber roller for embossing, adjusting ink and transferring ink. Its role is to deliver water and ink to the plate. The selection and manufacturing process of the rubber material will affect the quality of the rubber roller. The quality of the different rollers determines the quality, effectiveness and efficiency of the printing.
Analysis of surface structure of Dongguan rubber roller

The rubber roller is used for printing machinery as a rubber roller for embossing, adjusting ink and transferring ink. Its role is to deliver water and ink to the plate. The selection and manufacturing process of the rubber material will affect the quality of the rubber roller. The quality of the different rollers determines the quality, effectiveness and efficiency of the printing.
The surface roughness of the rubber roller is an important property that affects the transfer of ink and fountain solution by the rubber roller. Therefore, the surface roughness plays a vital role in printing. It can accurately measure the amount of ink and water delivered, maintain the balance of ink and ink, and stabilize the ink transfer to ensure the stability of printing color. At the same time, the ink can be uniformly separated into an ink film and a water film form to ensure smooth and continuous ink and dampening solution transfer, and the ink and dampening solution are accumulated to compensate for the uneven defects caused by the conveying process. However, in the actual printing process, the rubber roller is often in contact with chemicals, and some residual impurities are deposited on the rubber surface of the rubber roller. Some of the residue can be cleaned with water or solvent, but a small amount of impurities remain in the micropores of the rubber surface. bottom. These residues accumulate in the pores for a long time. Under the action of printing pressure and heat, the surface of the rubber roller loses microporosity and wears and glazes, that is, glazes.
Some companies choose to use some cleaners that have poor cleaning ability or excessive residue to clean the rubber roller, but these will speed up the process of glazing. If not treated in time, the glaze layer will become thicker and thicker, which will eventually cause great harm to printing.
Once the rubber roller is glazed, the surface area of ​​the rubber is greatly reduced, the hardness is increased, the strength is lowered, and the transfer performance to the ink and the fountain solution is deteriorated, resulting in difficulty in printing. The glazing makes the surface of the rubber roller hard, the elasticity is reduced, and the printing pressure is increased, which makes it difficult to adjust the pressure of the ink roller and the water roller. It also directly causes the ink density of the printing ink to be insufficient, the drying is slow, the ink balance is unstable, the paper waste is increased, and the rubber roller is difficult to clean.
After all, the surface structure of the rubber roller is in the selection and maintenance in use. The surface roughness of the printing ink roller is generally required to be 6 to 20 μm, and the surface roughness of the water roller for the alcohol fountain solution is 4 to 10 μm. If the water-capacity of the rubber roller is to be increased, the surface can be ground finely. An alcohol water roll having a surface roughness of 2 to 6 μm. After the selection, in order to maintain a good surface structure, it is the attention of the usual cleaning and maintenance.
