LASER FORM PROGRAM/BARCODE TEMPLATE IMAGE GENERATION FOR PRINT QUALITY INSPECTION

by William F. Diggin

ABSTRACT

  A laser-etch form program or a barcode template program is used to generate an ideal image of a label, to which the actual is compared to establish quality of print.

INTRODUCTION

  An approach is detailed in this paper to provide a method for inspecting the print quality of barcode labels or laser etched labels, in a generic fashion.

PROBLEM TO BE SOLVED

  Laser etching systems use form programs to etch product/customer information on products. Barcode printers use templates to perform similar operations. Current print quality inspection methods are manual. When automating this inspection process, a major problem is encountered. Because most of the information being printed or etched is customer or product specific, it is possible that a high variety of labels exist. This would require an automated system to be programmed for each specific difference. This is unacceptable as it is time consuming and needs reprogramming for new varieties or changes to existing labels.

PROPOSED SOLUTION

  A way of automating print quality inspection is to use the form program or template program at the time of label etching/printing. This program can be read and interpreted by the automated system to generate an image of how the print should appear. This image can be compared against an actual image of the label, acquired by a vision system....
