Abstract: A plasma treatment unit for a printer includes a gap directly upstream of its electrode. A sheet may bend into the gap, resulting in damage to the sheet or paper jams. The risk of this is reduced or prevented by a method for transporting sheets of print media between electrodes of a plasma treatment unit of a printer, including arranging the sheet and the electrodes, so that an edge of the sheet and an upstream edge of at least one of the electrodes are at a non-zero angle with one another, as the sheet passes over the electrode.

Abstract: A method of handling sheets in a printing device including a processing assembly that processes passing sheets by applying a processing parameter that is associated with a media type of each passing sheet, includes determining that a sequence of at least one sheet that is to pass through the processing assembly is to remain blank and that the sequence is preceded or followed by a sheet that is to be printed upon, controlling the processing assembly to apply the processing parameter for the sheet to be printed upon to this sheet to be printed upon during the passage of this sheet through the processing assembly, and for the sequence of at least one sheet that is to remain blank, controlling the processing assembly to ignore the processing parameter during the passage of the sequence through the processing assembly.

Abstract: A method of inkjet printing an elevated structure on a print medium includes depositing radiation curable marking material on the print medium, such that an array of spaced apart drops is formed, curing the spaced apart drops by irradiating the drops, forming the drops into a plurality of spaced apart, out-of-plane structures by repeatedly depositing a further drop of radiation curable marking material on each drop and curing the further drops, thereby adhering the further drops to the drop, wherein each repetition increases a height of the structures with respect to the surface. A backlight is provided behind the print medium to realize visual effects for an observer on the front side.

Abstract: A gas impingement unit includes a gas source and an array of nozzles connected to the gas source and directed onto a support and transport surface arranged for supporting sheet-or web-like media and moving them in a transport direction past the array of nozzles. The nozzles are evenly distributed over an area of the support and transport surface. The array is an array of interleaved nozzles and vent openings. The vent openings are arranged for allowing gas that has been blown out from the nozzles to escape in a direction normal to the support and transport surface.

Abstract: The present invention relates to a method for printing on an adhesive medium. The present invention further relates to a printed product. In addition, the present invention relates to a method for applying an image onto an object. The present invention also relates to a radiation-curable ink composition.

Abstract: A stacker module includes a lift table, a stacker configured to place sheets that are successively supplied thereto onto the top of a stack forming on the lift table, a controller configured to lower the lift table as the stack grows, a height-adjustable eject table, and an eject mechanism configured to transfer a completed stack from the lift table onto the eject table. The eject mechanism is height-adjustable for transferring stacks onto the eject table in different height positions of the lift table.

Abstract: A method for applying an image onto a recording medium includes applying a first layer of a radiation-curable ink onto a recording medium; curing the first layer; and applying at least a second layer of radiation-curable ink on top of the first cured layer. The coverage of the first layer is 1.0 g/m2 or less. The first layer of ink is applied onto the recording medium by applying a first ink from an ink set and the second layer is applied by applying at least the first ink from the ink set.

Abstract: Method for a printing system for processing a print job comprising the print data and the plurality of print job settings. Automatically an area of the recording medium is established that is deemed to be removed or made invisible during the at least one finishing action by a finisher. A digital object is retrieved from memory of the printer which is used for checking and monitoring at least one characterization of the desired end product. The print data are printed and also the digital object is printed at the automatically established area.

Abstract: In an ink-jet printing method, a neutralizing liquid is applied before a varnish is applied on a printed image to neutralize salt ions in a primer. An ink set and a kit of parts include such a neutralizing liquid and primer.

Abstract: The present invention relates to a method for applying an image onto a receiving medium, wherein the image is applied onto the recording medium by depositing a UV-curable ink and the ink is irradiated with radiation. The present invention further relates to a scanning printer and a software product.

Abstract: A printing method includes forming an image by applying marking material onto the surface of a substrate; subjecting the image to a fixation treatment; and applying a layer of an ionically stabilized varnish on the surface of the image. When the image has been formed, a layer of liquid solvent is formed on at least a part of the surface of the image, thereby causing ions to migrate from the marking material into the solvent and then to be absorbed into the substrate together with a part of the solvent before the varnish s applied.
