Gravure print or also intaglio print makes it possible to produce very accurate detailed designs with consistent quality and in higher quantities. Separations of the individual colours are made from the original design, which are then etched onto a print cylinder. Therefore one print cylinder is needed per colour. The entire surface of the cylinder rotates through an ink tray. The excess ink is removed with a squeegee. Only the ink in the depressions ("etched areas") remains on the print roller and transfers onto the wallpaper. Then it is possible to random emboss the printed product or emboss it in register (exactly matching the pattern). This results in a light to medium textured surface, which conceals unevenness in the wall surface and highlights the contours of the pattern. A maximum of 9 print units (= 9 different colours) are available. Special colours such as gold and silver can also be implemented. As rollers are used for printing, the pattern repeats every 53 cm or 64 cm - depending on the size of the roller. 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 cost-intensive printing procedure, the AP1000 - Design by Porsche Design Studio and Chroma collections, for example, are produced by our parent company in Wiehl-Bomig for Architects Paper.
