ANALYSIS OF VARIOUS DEFECTS DURING ELECTROMECHANICAL ENGRAVING OF GRAVURE CYLINDER

Gravure printing process is chosen to meet high quality, long run jobs and end user expectations. This printing process is known for its versatility and print fidelity. Electromechanical engraving is one of the prominent methods of cylinder preparation. But due to complex combination of process parameters the occurrence of defects is inevitable while cylinder preparation. The presence of these defects consequences in degradation of quality which leads to rejection of cylinder. The occurrence of these problems is unavoidable but nevertheless it can be controlled and minimized by optimization of process parameter and variables. Thus the present study aims to address different defects and problems occurred during gravure cylinder preparation. Main objective of this research work is to highlight, how frequently various defects happen during electro - mechanical engraving of gravure cylinders.
