Abstract

The Inkometer is the most commonly used for measuring ink tack. Several problems Involved in use of the Inkometer to measure tack are discussed. An attractive method of measuring ink tack is needed. This study concerns the relationship of ink tack to viscosity. Ink tack is of importance at the moment of printing. Since it correlates with the picking of paper, the relationship between viscosity and paper picking as correlected with the different press speeds were investigated. An I G T Printability Tester (Model-Al) with a printing spring attachment was used to apply ink to paper. An Inkometer and a Brookfield Viscometer were used to measure the ink tack and viscosity respectively. Comparisons were made between viscosity and ink tack with paper picking. The experimental factors studied were viscosity, ink tack and three levels of press speeds, which are defined as relatively low, medium and high. The results reveal that there exists a relationship between viscosity and tack. The results also show that the higher the viscosity of an ink, the more the increase in paper picking and that higher the press speeds with the same ink viscosity results in increased paper picking.
