Screen print or also rotary screen print makes it possible to produce designs with relief-type structures as well as mica and gloss details with consistent quality and in higher quantities.
Separations of the individual layers and colours are made from the original design, which are then transferred onto a print cylinder in the form of a finely perforated mesh. A squeegee then pushes the printing ink from the inside through the cylinder onto the wallpaper.
Next the wallpaper passes through a heated duct in which the expanding pastes rise similar to a yeast cake. This results in a medium to heavily textured surface, which conceals unevenness in the wall surface and has a special dimensional effect.
A maximum of 9 print units (= 9 different colours) are available. Special colours, such as metallic colours, are also available. As cylinders are used for printing, the pattern repeats every 53 cm or 64 cm - depending on the size of the cylinders. Depending on the pattern layout, the wallpaper is then hung in free or offset match. The available widths are, 53 cm, 70 cm and 106 cm.
Rule of thumb:
The higher the number of print cylinders utilized and the greater the circumference, then the more expensive are the fixed and set-up costs. The higher the ordered quantity, the lower the roll price.
In this capital-intensive printing procedure, the Haute Couture and Omnia collections, for example, are produced at our parent company in Wiehl-Bomig for Architects Paper.
