A numerical study of liquid transfer between two separating walls is carried out for modeling gravureoffset printing process. Printing was modeled by liquid transfer between two parallel separating plates and between a trapezoidal cavity and an upward moving plate. The governing equations are solved by the finite volume method and volume of fluid method incorporating with the structured grid and grid deformation technology. Influences of the separation velocity, the gravity force, the liquid viscosity, the surface tension and the contact angles on the liquid transfer are estimated. Effects of the contact angles at both the cavity side wall and the upper plate, the initial distance between the cavity and the upper plate, and the cavity shape are also discussed.
