POSTPRESS Clamping down—the right way

To determine the correct setting, test cuts can be made outside live matter in the area opposite the front marks on the sheet, or in the control strip. If the clamping pressure seems too high, the operator can reduce it from one test cut to the next until the pressure is too low and the knife pulls the material to be cut out of the clamp. After that, the clamping pressure is increased until the clamp holds the material securely.
