Abstract
The flow simulating ink transfer process of gravure printing applications was investigated numerically using a finite difference approach. The flow was assumed to be described by the Reynolds equation and the Oldroyd B model. In this simple situation, it turns out that the velocity and pressure fields are the same as in the Newtonian case. However, two non-zero components of non-Newtonian stress tensor survive and they are likely to change the characteristics of ink transfer mechanism compared with that of the Newtonian case. In this preliminary study, the behavior of the non-Newtonian stress tensor was investigated at several representative streamwise locations.
