VSOP Web Offset Press

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. 

Infinite size variability
The VSOP printing unit has plate and rubber blanket cylinders, which act as handy sleeves. The sleeves can be replaced manually in no time at all. Each sleeve axis has its own servo drive, which is why none of the gears need to be changed.

VSOP is a total solution for a whole range of applications and is used in the following markets:

  • Label printing: wrap-around labels made of paper or film, shrink sleeves,  wet-glue labels, self-adhesive labels, in-mould labels
  • Flexible package printing: films, laminates, food packaging
  • Cardboard box printing: folding boxes, liquid packaging, liner for corrugated board

Broad range of applications
Thanks to individual drives, the printing length can be changed within a defined range without affecting the printing quality. The speed of the impression cylinder can be adjusted for each of the printing units, ensuring that complex materials such as aluminum, thin foils or very thick substrates can be printed on with register accuracy.

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.
