A perfect print job can be ruined with folds that crack or are not accurately positioned. For smooth, flat folds and clean, clear scores and slits—properly placed—install a GUK SM50, SM54, SM70 or SM74 Score-Perf-Slit Unit. The units are small in size, so they are the ideal solution for improving the quality of production.
