Abstract

The invention relates to a method for printing decorative paper comprising a content of fillers and fibers. The decorative paper is supplied with an ink by means of an inkjet printing process or an intaglio printing process. The ink is received by the decorative paper, and a printed image remains on the decorative paper after the ink dries. Prior to being supplied with ink, the decorative paper is moistened until the fibers contained in the decorative paper contain between 10 wt.% and 20 wt.% moisture based on the weight of the fibers; the humidified decorative paper is supplied with ink; and the decorative paper is dried after receiving the ink.

Abstract

A single-pass inkjet printer is specified with a running path for guiding a printing medium along a running direction and with a number of print-head modules which extend over the running path in a transverse direction. It is provided here that the print-head modules are arranged in each case such that they can be introduced, in a manner which is suspended and self-adjusting, substantially in a vertical direction into a printing position, in which they are fixed to the unit. A single-pass inkjet printer of this type affords the possibility of a simple manual exchange of print-head modules, as a result of which the down times are shortened.

Abstract

The invention relates to a method for calibrating an inkjet printer (2), having a print head (8) comprising a plurality of ink ejecting nozzles (10) that can be actuated by means of a control signal. A specified calibration screen (42) is printed shortly prior to the intended print run by means of the inkjet printer (2), the value of a measurement parameter characterizing the print order is determined based on the printed calibration screen (42), and the ink ejection amount (29) per pixel is calibrated by adapting the control signal, based on the determined value of the measurement parameter. The invention further relates to a print product (22) printed by means of an inkjet printer (2) calibrated in such a manner.
