Solving the hot spots problem by moving the focus motor

When we have bad plate attachment we will see that as hot spots or focus problem.
In order to compensate over the bad attachment we can move the focus motor 15 micron far from the drum (decrease the number of focus motor)
In this position the focus motor will still be in the focus depth of 70 microns (-+35 micron).
