Abstract: A printing suction system for a printer can include at least one print bar with at least one print head, and at least one suction device arranged in proximity to an underside of the print bar thereby forming a gap through which a recording medium that can be printed to by the print bar can be directed. The suction device can extend along at least a portion (or the entire) width of the print bar. The section device can generate a suction pressure based on a suction pressure profile to suction and smooth the recording medium.

Abstract: A printing system and a method for printing a plurality of images on a first web and on a second web are disclosed. The printing system includes a print head, a feed unit for feeding both the first web and the second web simultaneously to the print head in a feed direction relative the print head, a wrap up unit for wrapping up both the first web and the second web simultaneously to form a first output roll and a second output roll respectively, a user interface configured to set a printing arrangement of the plurality of images on the first web and the second web and to input the print head, the feed unit and the wrap up unit for performing printing according to the printing arrangement by ejecting marking material on the respective webs. The printing system includes a prediction module for predicting a first diameter of the first output roll and a second diameter of the second output roll based on the printing arrangement.

Abstract: A web printing system has a loading tool to aid in the loading of new wide format web media. The loading tool is pivotable between a first position for loading a leading edge portion of the web onto the loading tool and a second position wherein an end portion of the loading tool extends above a print surface when in use. The end portion of the loading tool includes a beam element protruding from the loading tool in its pivoting direction towards the print surface, wherein in the second position the beam element is positioned with respect to the turn element, such that an S-shaped curve is formed in a web held on the loading tool. The curvature in the web significantly enhances the friction exerted by the beam element on the web, thereby stably holding the web in place.

Abstract: A roll-fed printing apparatus and a method for controlling the roll-fed printing apparatus for printing print jobs on a recording medium by means of a print mechanism.

Abstract: Method and printing system for processing a print job according to print job specifications. A realistic preview image of a plurality of pages of the print product is established and displayed taking into account the print job specifications and print job content. Parts of underlying sheets which parts become visible in the realistic preview image are determined and their content and physical properties are determined and incorporated into the realistic preview image.

Abstract: A method of operating a drop-on demand (DOD) jetting device having a nozzle, a pressure chamber filled with a liquid and connected to the nozzle and an actuator energized by a drive signal, wherein a periodic DOD signal determines whether or not a droplet is jetted out from the nozzle in a given DOD period, and the drive signal has a waveform configured to cause the actuator to excite a pressure wave in the liquid, the method further comprising the steps of a) energizing the actuator with a waveform that has a fixed pattern and extends over a time interval that is longer than the given DOD period; and b) ignoring the DOD signal in at least the first DOD period that follows after said period for which the step a) has been performed.

Abstract: A printing system and method for improving ink absorption in a print substrate by preventing evaporation includes a conditioned transport module arranged for transporting a printed print substrate from a (conditioned) image formation module to a drying/fixation module. The transport module includes a control system configured for controlling the relative humidity inside the transport module to at least 50%.

Abstract: A web printing apparatus comprising a support platen facing the processing station for supporting the web, when being processed by the processing station and a first guard for guarding a side edge of a web, the first guard being connectable to the support platen for guiding the web along a transport path, when the web is processed by the processing station. A detector is provided for detecting the first guard when connected to the support platen as well as a control unit configured for controlling the processing station to process the web, wherein the control unit is configured to identify the guard based on a detection signal provided by the detector to the control unit. Thereby, the first guard is identified by the control unit which may then control the movement of the print carriage to avoid the first guard, preventing collisions.

Abstract: A printing system for printing a plurality of images in a first web and in a second web, includes a print head; a feeder configured to feed both the first web and the second web simultaneously to the print head in a feed direction relative said print head; a user interface configured to set a printing arrangement of the plurality of images in the first web and the second web and to input the print head and the feeder for performing printing according to the printing arrangement; and a print-pause module for stopping printing of the printing arrangement, the print-pause module being configured to: provide to the user interface a print-pause arrangement in which a print-pause is arranged in the printing arrangement upstream the feed direction with respect to both the print head and a first image whose printing is being performed in the first web when the print-pause module is selected; and cooperate with the user interface to input the print head and the feed means according to the print-pause arrangement to st

Abstract: A method is provided for forming an image on a recording medium in a printer, the printer comprising a print head assembly for applying a curable ink on a recording medium to form the image, a transport path arranged for moving the recording medium in a transport direction along the print head assembly and a curing system; said curing system comprising a curing source, which curing source is arranged extending over the transport path in the transverse direction; the method comprising the steps of: moving the recording medium through the transport path in a step-wise movement in the transport direction along the print head assembly and the curing system; applying the curable ink on the recording medium by the print head assembly to form the image; and curing the curable ink, which is applied on the recording medium, by the curing source in a curing zone on the recording medium, the curing zone extending over the transport path in a transverse direction, the transverse direction being substantially perpendicula
