Quality Control During Laser Cut Rotogravure Cylinder Manufacturing Processes

Laser engraving of gravure cylinders is the latest and most exciting development now being used in the gravure market. Although laser engraving of gravure cylinders is a new variety for etching of gravure cylinders in gravure market, yet vulnerability of processes towards causing various defects exist in present system. Objective of this paper is to throw light on how frequently various defects happen during laser engraving of cylinders and to determine necessary steps to improve quality and efficiency of laser cut rotogravure cylinder production.The results indicated that pinholes, patches and depth variation are most frequently and majorly occurring problems in laser cut rotogravure cylinder manufacturing processes but improper dots and bludges are least occurring problems.
