The Effects of Ink Viscosity on the Ink Permeability inside Newsprint and Offset Paper
In order to explore the influence of ink viscosity on its permeability inside paper, three newsprints and three offset paper were firstly chosen to test their basis properties, then 5 ink samples including the original ink were prepared via adding different percentage printing varnish and their viscosities were measured. Under the definite printing condition, the 5 ink samples were printed on the surface of 6 papers with a printability tester respectively. At last, the ink penetrations inside these papers were all tested with a metallographic microscope. The study showed that the decreasing of ink viscosity would lead to the increasing of ink penetration depth, and paper properties had some effects on the ink permeability.
