The VSOP (Variable Sleeve Offset Printing) web offset press offers a simple and fast format change for the offset printing process. Using its patented sleeve technology, it's very easy to change the printing length without changing the complete offset insert. The biggest advantage of this fast and uncomplicated changeover is that it is very cost effective, especially when many different printing repeat lengths are required.
Flexible printing units
With this new technology, only two light weight sleeves need to be exchanged in each printing unit when switching the repeat length. You can changeover a complete job in just a few minutes. The sleeve technology, which has greatly contributed to the success of flexo printing, has now entered the world of offset. VSOP units are fully equipped printing towers, which can be continously set to any repeat length. This makes the VSOP an extremely flexible printing press, suited for nearly an unlimited range of different products.
VSOP is a total solution for a whole range of applications and is used in the following markets:
Label printing: wet-glue labels, roll labels made of paper or film, self-adhesive labels, in-mould labels, shrink films
Flexible package printing: films, laminate, foodstuff packaging
Cardboard box printing: folding boxes, drinks packaging
Servo drive
Each printing cylinder has an individual servo drive. This means that no gears need to be changed and maximum register accuracy can be reached. The individual drive of each printing cylinder offers the possibility to vary the print length with a certain percentage
without noticeable effect on the print quality.
Job change
Maximum press efficiency can be reached by preparing each print job off-press while the press is running. The quick changeover procedure and automatic presetting do the rest.
