Abstract
A method of forming a perforated cut line using a cutting plotter capable of accurately and rapidly forming a sheet with a perforated cut line along a cut line which is predetermined on a sheet and along which the sheet is to be cut. A cutter pressure at which a cutter is pressed onto the sheet is repeatedly reduced for a micro period of time at predetermined time intervals to form the sheet with a perforated cut line consisting of perforations and unperforated parts defined between the perforations in an intermittent manner.
