The job of dampening form rollers is to take up the fountain solution uniformly from the transfer or metering roller, transfer it to the printing form and provide a good ink-fountainsolution emulsion. When a dampening film is taken up by a dampening form roller, the film is stretched, as the dampening form rollers runs much faster than the metering roller. Here, it is important that part of the fountain solution is emulsified in the ink. Thin negative lines and structures in the image are kept free of ink by the fountain solution emulsified in the ink which is released, when the emulsion separates under the pressure of the plateroller. The hard ness of Damping Rubber Rollers should be in netween 24 shore A to 28 shore A ± 5 shore A

In modern technology these rollers are covered with the plastic which have better properties and the surface of the roller is given mirror finish. The results of these kind of rollers are very high in quality then copper rollers the hardness of the Plastic Coated Rollers is 100 shore A
