A print job having a number of pages is printed in a continuous mode, on media advanced at a constant speed. The print job can thus be effectively treated as having a single page. The media that are advanced for printing the print job can similarly be effectively treated as being a single medium.

A machine for processing individual sheets comprises at least one processing station, in particular in inkjet printing station, and a transport system (100) for transporting the individual sheets through the processing station, along a transport direction. The transport system (100) comprises at least one gripper conveyor (150) movable along the transport direction, for gripping one of the individual sheets defining a sheet position in transport direction. The transport system (100) further comprises at least one support conveyor (190) movable along the transport direction for supporting a region of the individual sheet, wherein the support conveyor (190) comprises a vacuum system for supporting the individual sheet on an interacting surface of the support conveyor, the vacuum system comprising a plurality of orifices in the interacting surface. The machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

The invention comprises an apparatus and method of use thereof for processing a machine produced emulated handwritten document prepared on a marking surface, comprising the steps of: receiving a print job order; digitally generating a reference image of the print job order; machine plotting with a plotting pen and a downward force of one-half to forty ounces applied to said plotting pen an indentation trail to form input text on the marking surface; digitally imaging the input text on the marking surface to form an actual image; and in a quality control step, digitally comparing the reference image to the actual image prior to insertion of the print job order into an envelope.

An image forming apparatus includes a printing device, a rotator, an upstream support stand. The printing device prints an image on a plate-shaped printing medium. The rotator rotates while nipping the plate-shaped printing medium and conveys the plate-shaped printing medium to the printing device. The upstream support stand supports the plate-shaped printing medium at a position upstream from the rotator in a conveyance direction of the plate-shaped printing medium and includes a mount. The mount is detachably attached to the rotator.

A method of depositing printing fluid on a sheet of corrugated media comprises determining a deformation of a sheet of corrugated media, adjusting control parameters for a plurality of nozzles based on the determined deformation, and depositing printing fluid from the plurality of nozzles onto the sheet of corrugated media according to the adjusted control parameters.

A sheet conveying apparatus includes a conveying roller, a pinch roller, a holding member, and a pressing device. The pinch roller includes a roller shaft and a roller body rotatable relative to the roller shaft. The roller shaft includes a first end portion and a second end portion. The holding member holds the roller shaft movably in a first direction. The pressing device presses the roller shaft in a pressing direction such that the roller body is pressed against a peripheral surface of the conveying roller. The first end portion of the roller shaft has a first contact surface being a planar surface. The second end portion of the roller shaft has a second contact surface being a planar surface. The roller shaft is disposed such that the first contact surface and the second contact surface are oriented in the pressing direction.

An inkjet printing device includes a vacuum-belt and vacuum-table including a flat area positioned between a first and second air-groove aligned along a conveying direction. The vacuum belt includes a first column of vacuum-belt-air-channels connected to the first air-groove, a second column of vacuum-belt-air-channels connected to the second air-groove, and a third column of vacuum-belt-air-channels connected to the flat area by a plurality of air channels formed by a rough layer at the back-side of the vacuum-belt and/or a rough layer on the flat area.

A printing apparatus includes: a platen that supports a printing medium; a head-portion that discharges droplets toward the printing medium while reciprocating on the printing medium; an interval-adjusting-mechanism that adjusts an interval between the platen and the head-portion; and a controller that controls the head-portion and the interval-adjusting-mechanism, in which the controller has a first printing mode in which printing is performed while the interval is set to a first interval and a second printing mode in which the printing is performed while the interval is set to a second interval that is larger than the first interval, as a printing mode in which the printing is performed on the printing medium. The controller controls movement of the head-portion such that a movement stop time of the head-portion when a movement direction of the head-portion is reversed is longer in the second printing mode than in the first printing mode.

An inkjet printer having at least one print head in which an aerodynamic element is placed before (e.g. in a transport direction) a recording medium (e.g. in the form of a sheet or page or plate) to reduce or avoid turbulences that may arise due to the relative motion between print head(s) and recording medium at an edge of the recording medium.

A corrugated fiberboard printing device includes a protection device which regulates approaching of a corrugated fiberboard within a predetermined distance against an inkjet head, and a controller. The protection device includes multiple regulation devices which are juxtaposed in a width direction of the corrugated fiberboard, and a movement mechanism which moves each of the multiple regulation devices in the width direction. The controller includes a specific column setting unit which is set to classify a specific column, in which a printing quality is less influenced even when the specific column is regulated by the regulation device, with respect to the corrugated fiberboard in a sheet width direction based on order information, and a movement mechanism control unit which controls the operation of the movement mechanism and moves each of the regulation devices so as to regulate the corrugated fiberboard in the specific column.
