Labels may peel from a carrier while a section of the sheet separates along a perforation. Those lines need different behaviour. The converter should state which layers each line cuts when ordering the steel-rule flatbed die.
State each line’s function
At a label contour, facestock and adhesive separate while the liner remains functional. Perforation creates alternating cuts and bridges for tearing. State whether that tear line must also pass through the liner. A general instruction to cut labels does not distinguish the requirements.
Supply separate cutting layers
Use separate KISS CUT and PERFORATION layers, with a third layer for any through-cut outer boundary. Inspect close approaches and crossings between the perforation and label contours. Different functions may require different rule choices and settings; similar-looking lines do not imply equal cut depth.
Account for the carrier’s handling role
A weakened liner can let a sheet separate before use. Define peel direction and tear direction together. Identify actual facestock, adhesive and liner construction rather than choosing from the face material name alone. For roll-fed work, specify the intended flatbed die-cutting unit.
Review both functions individually and together
On the converter’s own sample, first check peeling and liner usability, then separation along the intended perforation. Finally check whether tearing lifts a neighbouring label. Record the affected region and material for revision. Increasing pressure across the whole tool is not an automatic remedy.
