Not only underpacking but also tensioning of a blanket is of importance. In the case of excessive tensioning, the compressible layer looses its thickness and deforms, which affects the printing properties; in the case of insufficient tensioning, the dot is extended (deformed). Therefore always follow the instructions of machine manufacturers for tensioning values. For a correct and easy blanket tensioning use a torque key.
