| Abstract: |
As part of an on going study of the process physics of flexographic printing, a comprehensive study has been undertaken of the effect of ink viscosity, engagement, line ruling and anilox volume on the ink transfer to paper. The viscosity of the ink was varied in two manners, one by dilution with solvent reduced pigment concentration as well as the viscosity and the other reducing the viscosity at constant ink strength. The anilox volume was found to have the greatest effect on the ink transfer in the solid coverage areas. However, in interaction was found between the coverage, the line ruling and the anilox cell size. This can be attributed to the deformation of the half tone areas of the plate into the anilox cells and in part explain the inconsistency found by previous researchers in highlight regions on the plate. The engagement was found to increase the ink transfer as more ink was impressed into the substrate. |
