    Strezovski - Special tooling required, I trained on them at the factory in '95, they were developing a couple of ways to set plate/blanket then, but no simply mechanical means to adjust properly. Maybe something has changed since then??? Good Luck

    I put 0.50mm papper under the blanket to have enough presure.

    There is only one way to accurately adjust plate/blanket pressure on SM74. Yes, special tools are required. With the machine on impression, a small piece of pressure sensitive paper is placed on the bearer and inched between the bearers. The sheet is then measured and a meter outputs a value. This value must be between a tollerance defined by the factory. Without this meter its impossible to set accurately. My question, why do you think you need to adjust plate/blanket pressure?
