Lassco Wizer Scoring Equipments

The machine’s working width should exceed the sheet dimension that will pass through it in the scoring direction. A wider unit can handle larger covers, menus, folders, and multi-up printed sheets before trimming. Do not assume a sheet will always enter along its shortest side, because the location and direction of the fold may require another orientation. Measure the largest regular job and include guide clearance. A compact scorer may suit letter and small-format work, while a wider system offers more flexibility for tabloid or oversized sheets. Floor or bench space also matters, especially when long sheets extend beyond both sides of the machine. The operator should have enough room to keep the stock square against the guide throughout the scoring pass.

Perforating creates a controlled tear line for tickets, coupons, forms, payment slips, detachable cards, and other printed materials. Equipment with interchangeable scoring and perforating wheels can support both operations without requiring separate machines. Perforating and scoring equipment should be selected according to stock range, sheet width, perforation pattern, and production volume. A perforation that is too fine may be difficult to tear, while an aggressive pattern can separate during handling. Test the actual stock and intended tear direction. The wheel must be installed and aligned correctly, and operators should clearly identify which tool is fitted before processing valuable printed work.

Paper generally folds more easily parallel to its grain. Folding against the grain increases resistance and can cause cracking, uneven edges, or spring-back, especially with heavy coated stock. A correctly adjusted score can reduce these problems but may not eliminate them completely. Determine grain direction before printing when the final fold is critical. The scoring channel depth should suit the material without cutting or weakening it. Heavy toner across the fold may still show stress even when the paper is scored. Test both orientations when production planning allows. If the job must fold against the grain, the score setting may need adjustment, and a slower controlled fold may produce better results than forcing the piece immediately after scoring.

Useful accessories can include replacement scoring wheels, perforating wheels, guides, stops, and any small mounting parts required by the machine. The range of scoring equipment accessories should be matched to the exact model and shaft design. Keep commonly used wheels protected from damage because a nick or flat spot can mark every sheet in the same position. Record successful guide settings for repeat jobs and store adjustment tools close to the machine. Before fitting or removing a wheel, disconnect power when required by the instructions. A clean table and accurate guide are as important as the wheel itself because dust, adhesive residue, or a loose stop can cause skewed scores across an entire run.
