Underpacking Material
Underpacking is used to achieve a precise setup, fitting and mounting of printing blankets and printing plates
on the cylinder. It may consist of various materials ranging from cardboard
to special foils. Packing not only compensates for differences in thickness,
but also influences print quality and the service life of the blankets
and plates in the press.
Finito®
Finito® is a new type of packing foil consisting of a polyester carrier with a special TPU coating. The foil's properties have a positive effect on print quality and blanket life. Due to its high resistance to chemicals and mechanical resilience, Finito® is a cost-effective alternative to conventional packing materials. The thickness and size of Finito® foils are adapted to the individual press models.
Coating Form Cylinder Underpacking
While blankets used to be the standard packing material of the past, today they are rarely used underneath the printing blanket. Unlike cardboard or foil packing, these blankets produce a "softer" cylinder packing.
We offer the following blanket: DV black, thickness 1.00 mm, available up to 1480 mm width.
Underpacking Sheets
A special calibration method produces very hard cardboard, ensuring high print quality and low dot gain. The cardboard is waterproofed to prevent the penetration of moisture that would lead to undesired swelling. An "anti-slip coating" keeps the cardboard from sliding on the cylinder.
Underpacking Foils
Standard foils are made of polyester and designed to be used on the plate or blanket cylinder. The dimensional stability of these foils, their resistance to printing chemicals and their long service life are important advantages compared to conventional cardboard packing. The foils are available in different versions, including self-adhesive.
