A Combination of High-Precision Perfecting and Smooth Sheet Travel - the Perfecting Technology of the Speedmaster XL 105
Fully automatic change-over of the perfecting device with
eccentrically-shaped reversing drum ensures ultra-smooth sheet
travel with exceptional register accuracy.
The variable AirTransfer system, whose sheet guide plates
equipped with innovative Air Jet technology and the
TransferJacket cylinder jacket, is the cornerstone of reliable
sheet guidance and ultimate print quality in perfecting printing.
The swing-out cylinder shells, before and after sheet
reversal, extend automatically when switching to perfecting
mode. In this way, they provide optimum support for the
sheet.
The intake ports in the storage drum enable optimum
registration.
The shells of the transfer cylinder are equipped with
TransferJacket cylinder jackets with an ink-repellent surface
finish. It prevents that ink being deposited there permanently
and thus minimizes the need for cleaning.
The PerfectJacket impression cylinder jacket has an uneven
surface, which reduces the area in contact with the freshly
printed sheet; the ink-repellent surface is also sealed to reduce
ink buildup on the cylinder jacket.
The dynamic sheet distance control device monitors and
automatically corrects sheet travel by adjusting the air flows to
ensure optimum sheet transfer.
