Driven by increasing demands on process automation and optimization, marks-3zet GmbH & Co. KG (Muelheim a. d. Ruhr, Germany), a specialist for underpacking materials and waterless offset printing, has unveiled its unique new compressible underpacking sheet Highline^®.

With Highline^®, marks-3zet introduces a versatile underpacking solution with a composite structure that gives printers a cost-efficient, high-quality product with an optimal lifespan.  Highline® simultaneously enables a consistent and optimal print quality. 

The solution consists of a calibrated substrate layer and a polyurethane (PU) top layer, which results in a highly flexible, compressible underpacking sheet. The PU layer guarantees optimal smash resistance and perfectly absorbs and compensates machine vibrations, therefore offering optimal protection against crumpling. 

Moreover, Highline^® is water- and solvent-resistant and can extend the lifetime of the printing blanket.  

Highline^® is a non-adhesive underpacking sheet, leaving printers more room to adjust the underpacking thickness as desired. Highline® can be easily and quickly mounted on almost all cylinders. It is especially recommended for high-speed commercial and rotary presses. 

Highline^® can be used both as a single sheet and a cover sheet. As a cover sheet, Highline^® offers extra compressibility and stability to standard underpacking sheets. 
marks-3zet currently offers Highline® in the thicknesses 0.4 and 0.5 mm for all formats.
