Abstract:
1. A method for calibration of laser ablating energy versus ablating depth in a non-living material, comprising the steps of: storing correlated data of detected depths of laser ablated areas of a first sample of a selected non-living material and correlated laser energy levels for each area in a memory to provide calibration of a laser for the selected non-living material; ablating a desired depth in a different sample of said non-living selected material with a first laser; interpolating laser ablating energy levels for the desired depth in the different sample of said material in accordance with said stored correlated data corresponding to said first sample in the memory; and controlling the laser to laser ablate the selected material in accordance with the interpolated laser ablating energy levels, wherein said different sample is a material on which an image is to be created for printing.
