The print quality has been a point of major concern among digital presses. Digital presses are widely used due to their high productivity, versatility, and ability to print variable data. Electro-photography has come to exist with two major inking technologies i.e. dry form and liquid form of toner. The present study focuses on quantification of printing defects in liquid toner and dry toner electrophotography presses on cellulosic substrates and comparing the same. With the results it was found that at one hand paper moisture, mis-feed, ink drop out and warming up are major printing defects in DEP, on the other print quality issue, paper jamming, oil dripping, bid engaged / dis-engaged, registration out are major printing defects in LEP presses. This research paper highlights the importance of selecting the right digital press technology for printing on cellulosic substrates to avoid the printing defects.
