Comparative Analysis of Colour Difference (∆ E) in Digital in Dry Toner Based Printing on Gloss Coated Paper

Reproducing correct colours in printing has been a point of strong concern among printers. Matching colour with original is the need of hour. But small difference in colour is always in the tolerance limit. ∆ E in offset printing process should be less than 2 as per standards. But in the digital printing no much research has been introduced regarding colour difference (∆ E). Objective of this paper is to find out ∆E in dry toner based digital printing on gloss coated paper. A master test chart was prepared using various tint patches, high quality test images and quality control strip produced using i1 basic pro. The test chart was printed in Digital Print Application Laboratory, Department of Printing Technology, GJUS&T, Hisar on Richo India Ltd. Digital Printing Press. The results indicated that ∆ E in dry toner based digital printing is comparable to sheet-fed offset printing on gloss grade coated paper stock.
