COMPARATIVE ANALYSIS OF RUB RESISTANCE IN SHEET - FED OFFSET AND DRY TONER DIGITAL PRINTING ON UNCOATED, GLOSS COATED AND MATTE COATED PAPER STOCKS

In printing world, Sheet - Fed - offset has been popular and trending method of printing since some decades. Digital printing methods are getting popular now a days because of its quality and less production time. This paper throws light on comparison of rub r esistance of sheet fed offset and digital printing process on uncoated, gloss coated and matte coated paper. To test the rub resistance a master chart was prepared consisting on line images, middle tone images and solid areas. The chart was printed by both printing processes on all above mentioned three grades of paper. The samples were tested using digital scuff tester. The results indicated that digital printing has more rub resistance compared to sheet fed offset.
