Abstract: Printing with a single colorant a security feature imperceptible to the naked eye. For a digital security image having a first region formed by a first pattern of binary pixels and a second region formed by a different second pattern of binary pixels, the first and second patterns are printed with the single colorant. A darker one of the first and second printed patterns is determined. The security image is printed with the single colorant, the region corresponding to the darker printed pattern printed at a reduced gray level such that the printed first and second regions appear substantially indistinguishable to the naked eye.

Abstract: In a method to operate an ink printing apparatus, and in an ink printing apparatus, a recording medium is directed through a printer. The recording medium is subsequently supplied to a dryer having at least one heating saddle and a drying channel arranged at the heating saddle. In the dryer the recording medium is directed past the heating saddle. A negative pressure is generated in the drying channel via an air exhaust arranged at one end of the drying channel. In the printing operation, in a region of the heating saddle a negative pressure is exerted on the recording medium in a direction of the heating saddle so that the heating saddle is then in contact with the recording medium in order to dry the ink on the recording medium. Upon interruption of the printing operation with braking of the recording medium, the negative pressure in the direction of the heating saddle is deactivated at a beginning of the braking.

Abstract: A method for printing on an object, for instance on an object made of a foamed material, includes applying ink to a surface of the object in accordance with digital image information in an inkjet printing process and irradiating the ink by electromagnetic radiation, preferably containing an IR proportion, to cure or dry the ink. The ink is directly heated by the irradiation and the material of the surface is indirectly heated by the irradiation by thermal conduction from the ink, causing the material in a region to experience a volume change. In this way, it is possible to simultaneously print on the material and to provide the material with a relief structure/to digitally emboss it.

Abstract: A cutter has a first cutter blade moving mechanism 24 that moves a first cutter blade 21 reciprocally between a forward position 21A where recording paper 3 is cut and a retracted position 21B separated from the forward position 21A; and a second cutter blade moving mechanism 25 that moves a second-cutter blade 22 between a contact position 22A where the paper is cut in contact with the first-cutter blade 21 and a release position 22B separated from the contact position. The second cutter blade moving mechanism 25 sets the second cutter blade 22 to the release position 22B before the first cutter blade moving mechanism 24 moves the first cutter blade 21 from the forward position 21A to the retracted position 21B. Wear and noise can be prevented because the two cutter blades 21, 22 do not contact after cutting the recording paper 3.
