Many cutters do not have blade compensation (blade offset) built into the cutter’s firmware. This means that when cutting small text for example, the corners will be cut across and/or rounded off resulting in very poor quality results. The Vinyl Spooler comes with a Blade Offset Calibration tool that cuts a physical test from the target Vinyl Cutter, or Plotter which is used to establish which offset amount (value) best suits the Cutter, or Plotter in question
