Research on Computing Model of the Cell Volume for Electronic Engraved Gravure

Abstract

Gravure printing has been applied widely in flexible packaging, building materials and other fields, and amount of ink transfer is an important factor to affect the printing quality and depends largely on the volume of the gravure cell. The volume of cell is affected by gravure process parameters such as screen lines, cell angle and engraving needle angle, so the volume of cell is calculated difficulty, and it is difficulty for the optimization of the gravure plate-making process. This paper presents a computing model calculating the volume of gravure cell. The cells for three kind of dot coverage rate are carved with 70LPC screening lines and 120°needle angle, their opening length, width and depth are measured by cell measuring instrument, their relation is been found by MATLAB and the computing model is built to calculate the cell volume model .The results show that the computing model is suitable for different cell angle, and the cell volume depends the screening rules, cell angle, needle angle and the cell depth. If the depth for different dot coverage rate is measured the cell volume will be calculated.
