The Effects of Ink Viscosity on the Ink Permeability inside Newsprint and Offset Paper
Abstract:
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.
