Walker-Fetsko equation

The ink transfer rolls apply a uniform film of ink to the printing plate or roll tills ink film is transferred directly to the paper substrate, or first to the printii blanket and then to the paper substrate. During printing, the ink film penetrates into the porous paper substrate, and that part of the ink film remaining between the substrate and the plate splits, leaving part of the film on the substrate and part on tiie plate. This ink film splitting is described the Walker-Fetsko equation 0 ... 

These concepts are modelled in the Walker-Fetsko ink transfer equation ...
