Dot gain, solid ink density and print contrast are important parameters in every printing process. The main objective of this paper is to study of solid ink density, dot gain and print contrast while printing on Dry Toner based Digital Press on uncoated, gloss coated and matte coated paper. All paper tests were carried out in Avantha Centre for Industrial Research and Development, Yamuna Nagar. A test master was prepared by using various quality control elements (high resolution images). All above the three varieties of papers were printed on Digital Printing Press in Digital Print Application Laboratory, Department of Printing Technology (G.J.U S&T, HISAR). The solid ink density, dot gain and print contrast were measured using spectro- densitometer available in Department of Printing Technology. The result indicated the variation in dot gain, solid ink density and print contrast while print on a dry toner based digital press.
