Patent ID: 7888621

Claim:
A method for automatically adjusting the operational parameters of a laser cutter, comprising: cutting a calibration test pattern into a substrate by a laser cutter, the substrate being defined by a laminate structure in the form of a corrugated container board having a top liner board, a bottom liner board, and a corrugated medium disposed therebetween and wherein the calibration test pattern includes a plurality of spaced apart cuts of varying depths; capturing data representative of the test pattern prior to analyzing the calibration test pattern; analyzing the calibration test pattern cut into the substrate utilizing computerized image analysis wherein analyzing the calibration test pattern includes comparing the calibration test pattern captured by an image capturing device with a reference image having one or more of the desired cut depths wherein the desired cut depths include (a) a depth of cut sufficient for surface marking, (b) a depth of cut sufficient for removal of the top liner board, (c) a depth of cut sufficient for cutting through the top liner board and the corrugated medium, and (d) a depth of cut sufficient for cutting through entire substrate; and modulating the laser cutter during a subsequent processing of the substrate.
