Quality Analysis of Paperboard Products Printed by Rotogravure Process

The purpose of this study is to analyse the quality parameters of paperboard products mainly Hinge Lid Package (HLP) printed by 10 colours Rotogravure which are stacked in Good Pallet and Autosplice Pallet. The observation methodology and the collection of data is based on interpretative approach which contains three parameters: Print to Cut, Cut to Crease & Registration Mark. An experimental approach has been taken, since the aim of the study is to check the variation of print quality in HLPs stacked on Good Pallet which are dispatched to the market for sale and also check the variation of print quality of HLPs printed during auto splicing in order to find out the utilisation of that HLPs for marketing purpose. The study shows that the small variation of quality parameters i.e. Print to Cut, Cut to Crease and Registration Mark beyond the tolerance value affect the print quality of package. A statistical model and graphical analysis was designed to determine the influence of quality parameters on defect minimization. As a main conclusion, checking the quality parameters in regular interval of 30 minutes maintain the print quality to a greater extend.
