8.1. Pressure Distribution Function
The pressure distribution function reflects the real pressure vs. rotation angle at a certain
point on surface. It is measured for every roller turn. In first part their course depends on
applied conditions like line force, elasticity of elastomer roller but also on friction of applied
ink. The splitting behavior is described by the second part of the line course.
