Contour Cutting Wizard
Add registration marks, print, and cut from 1 screen - with helpful prompts from the software wizard.
VinylMaster Cut is equipped to provide precise contour cutting whether your machine works with LAPOS (Laser Positioning Sensor) for manual contour cutting or ARMS (Automatic Registration Mark Sensor) for automatic contour cutting. Contour cutting, cutting the outline around a printed image, is perfected with VinylMaster Cut for applications like stickers and custom printed labels. The GUI that VinylMaster Cut offers provides you with diagrams to preview and modify before completing your contour cuts. This preview will even assist you in loading your media into your cutter correctly. VinylMaster Cut has an advanced feature to allow for sensitivity control over your cutters optical eye when using the ARMS feature. This feature ensures that your registration marks can be read when cutting matte, gloss, laminated or even reflective material.
You can also try a demo, select which version upon startup, and play around with the features.
