: Do not press off later than the hole
section end position since ink
seeps from the bottom end of the
master.
IMPORTANT
Adjusting the printing area means that the cam curve goes up and down as shown in the figure. The timing of
drum ON / OFF varies depending on the cam curve`s up and down. The ON position is before the drum hole
section, so the printing area is not influenced. (Do not shorten the printing area length as it is influenced.)
The OFF position is only changed and the printing area is adjusted.
