COLOUR DIFFERENCE ANALYSIS OF SHEET-FED OFFSET PRINTING PRESS FOR MONO-CARTON BASED PACKAGING APPLICATIONS

The main function of any printing industry is reproducibility of the original and to produce the exact colour. The offset printing process is a process which deals with maximum number of quality variables amongst all other printing processes. The slight variation in these variables can result in colour difference (∆E). This paper deals with the study of colour deviation after controlling the Solid ink density and adopting suitable strategies
