An example method for controlling a carriage of a printing device is described. In one implementation, a target velocity value that satisfies a sharpness threshold is filtered by a processor resource of the printing device, a feed forward term is generated using a continuous model applied to the filtered velocity input using a plurality of electromechanical parameters, a feedback term is generated based on a difference between an expected pulse-width modulation (PWM) profile and an actual PWM profile, and a voltage to be provided to a motor of the carriage is adjusted based on the feed forward term and the feedback term.

A printing assembly comprises a medium support surface, a guide assembly and a carriage support structure for moveably supporting a print head carriage on the guide assembly. The guide assembly is arranged to move the print head carriage in a carriage plane, which carriage plane is parallel to the medium support surface. The guide assembly comprises a guide beam; and a guide rail arranged on the guide beam. The guide rail and the guide beam each extend in a scanning direction. The printer carriage support structure comprises a guide frame arranged on the guide rail and the guide frame is moveable in the scanning direction and extends in the scanning direction between a first support position and a second support position. The guide frame is supported on the guide rail at said first support position and at said second support position. A carriage frame is moveably supported on the guide rail through the guide frame. The carriage frame is coupled to the guide frame such that the carriage frame is moveable relative to the guide frame in the carriage plane.

A system (100) and method for printing an indicia on a graphic medium (103) is described. A print mechanism (122) is operable for marking multiple printouts of the indicia at a target position on the graphic medium (103), and for outputting a printed media product (31). The printed media product (31) has a first output group of the marked printouts, and continuous with the output of the first group of printouts, at least one output group of the printouts marked subsequent to the first output group. A controller (144) is operable for adjusting the print mechanism (122) in response to an input (135) related to an evaluation of the printouts marked on the first output group. The adjustment conforms a position at which the printouts are marked in the at least one subsequent output group spatially to the target position.

Attachment systems and associated structures are configured to provide accurate installation, removal and reinstallation of modular print bars in a printing system. An exemplary attachment system comprises one or more matched attachment assemblies, comprising latches and pins, wherein the latches are fixedly arranged with respect to print bar bays, and wherein each of the print bars is slidable with respect to a corresponding print bar bay. When a print bar is alignably positioned with respect to a corresponding print bar bay, a corresponding pin is securable to the latch, to accurately affix the print bar with respect to the print bar bay. The attachment system provides repeatable and accurate registration of the print bar with respect to the printing system. The enhanced attachment system may preferably comprise comprises an actuators, e.g. pneumatic or electric, to controllably engage or disengage the pins and/or latches.

An adjustment mechanism is structured to adjust and fix a liquid discharge head in position on a base plate. The adjustment mechanism includes a first plate, a second plate, a pivotable cam, and a first biasing unit. The first plate is changeable in position in a circumferential direction relative to the base plate. The first plate is fixed to the base plate. The second plate is mounted on the first plate movably relative to the first plate in a direction different from the circumferential direction. The liquid discharge head is fixed to the second plate. A first biasing unit biases the second plate toward the pivotable cam in a horizontal direction to prevent the second plate from lifting upward off the first plate. The pivotable cam is operable to move the second plate against an biasing force of the first biasing unit and to locate the second plate.

An inkjet printing apparatus comprises an inkjet print head arranged to be moveable in a direction of movement along a guiding assembly. The guiding assembly comprises a support structure; a strip mounted on the support structure, the strip being substantially rigid and straight in a first direction substantially perpendicular to the direction of movement and mounted in such way that a straightness in the direction of movement is provided; and an air bearing system operatively coupled to the strip. The strip extends in a vertical plane, the vertical plane being substantially parallel to the direction of movement and being substantially parallel to the first direction. The air bearing system is configured to control a position of the inkjet print head in a horizontal plane relative to the strip during movement of the print head in the direction of movement, the horizontal plane being substantially perpendicular to the vertical plane. Employing such a strip and a suitable mounting method for mounting the strip on the support structure, it is enabled to select a cost-effective and/or light-weight support structure.

Ein erfindungsgemäßes Verfahren zum Bedrucken wenigstens eines Abschnitts (3) einer flachen oder bevorzugt gekrümmten Oberfläche (2) eines Objekts (1), wobei ein Tintenstrahlkopf (4, 4a, 4b) durch eine Relativbewegung zwischen Tintenstrahlkopf (4, 4a, 4b) und Objekt (1) entlang einer ersten Bahn (A) bewegt wird und dabei eine erste Spur (a) druckt, und entlang einer zweiten Bahn (B) bewegt wird und dabei eine zweite Spur (b) druckt, zeichnet sich dadurch aus, dass sich eine erste Spurkante (a') der ersten Spur (a) und eine zweite Spurkante (b') der zweiten Spur (b) in einem Punkt (P) treffen und im Punkt (P) einen Winkel (α) zwischen etwa 1° und etwa 179° einschließen. Das Verfahren erlaubt es, die gekrümmte Oberfläche (2) ohne wahrnehmbare Spuranschlüsse zu bedrucken.
