Abstract
The multiple printing plate mounting system of the present disclosure may be used to mount multiple flexible printing plates simultaneously onto a printing sleeve. The system has a back rotary vacuum plate with a plurality of distinct vacuum zones and may be controlled via valve by a computer control system. A filler plate may also be controlled with the same vacuum patterns. The filler plate will move minutely side-to-side. A front plate with match-controlled vacuum patterns may also have a servo to control front-to-back-movement. The distinct vacuum zones are used together with the movable front, back, and filler vacuum plates to selectively, individually, and independently align the flexible printing plates prior to mounting.
