POSTPRESSFixomat will fix it

During the cut, the material cannot slip away or wobble. When Fixomat is used, the high-speed cutter control system automatically changes the backgauge position, detecting the desired position and correcting the backgauge position correspondingly. There is one caveat: Fixomat is applicable only if lay marks have already been used on the automatic jogger to compensate for concave paper edges. Lay marks are a standard feature on automatic joggers with air-removing rollers.
