A printing device including a laser (10) for generating at least one laser beam, a controller, a print head (16) having a plurality of orifices (32), and an ink supply for supplying ink to the print head. The controller modulates the at least one modulated laser beam according to image data to be printed. The at least one modulated laser beam selectively generates a directional acoustic wave within the print head, thereby inducing an ink droplet to exit a selected one of the orifices onto a printing substrate. A print head including a single buffer chamber (26), a body (28), and a single ink chamber (30). The buffer chamber stores a buffer liquid therein with the body forming one wall of that chamber. The ink chamber shares the body as a wall. The ink chamber stores ink therein and has a plurality of orifices on a wall opposite to the body.

Disclosed is a method and apparatus for improving printed image quality. The image quality improvement is achieved by differentially curing different image elements such as continuous tone elements, uniform tinted and solid elements, color elements, line art and text elements. A delay in the activation, duration and variation in the intensity of the curing radiation or a mix of some or all of them that follows the ink droplet on substrate deposition controls the ink droplet spread and accordingly the image quality.

The inkjet recording head (100) in this invention is equipped with multiple edge shooter type head units (20) with a head chip formed by nozzle discharge surfaces, positioning plates (41) distributed in parallel rows that slope with respect to the line array direction of the multiple head units (20), where in addition to the distribution of the positioning plates (41) in parallel rows that slope with respect to the line array direction of the multiple head units (20), the nozzle intervals in the line array direction of 2 nozzles (21 a) adjacent to each other on the straight line of the nozzle injection surfaces form the slope angle that corresponds to the specified resolution.

Examples described herein include a print media edge repair system (100) that includes a first repair element (105) disposed adjacent to a media handling path to repair a leading edge (111) of a sheet of print media (110) as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repairs may also include a second edge repair element (105) disposed opposite the first repair element across the media handling path to repair a trailing edge (112) of the sheet of print media as the sheet of print media moves into the position relative to a printing system (800).
摘要:
Certain examples described herein relate to printing systems and methods of operating the same. In an example of a printing system, a nozzle diagnostic mechanism obtains information relating to a condition of a first nozzle set of a print head following a first period of an established printing operation, and a nozzle compensator receives information relating to the condition of the first nozzle set from the nozzle diagnostic mechanism. Based on the received information, the nozzle compensator then causes a second nozzle set of the print head to be operated in place of the first nozzle set of the print head during a second period of the established printing operation. In an example of a method of operating a printing system, status information that relates to a condition of a first nozzle set of a print head is determined during a print production operation. A second nozzle set of the print head is then caused, based on the status information determined, to be operated in place of the first nozzle set to continue the print production operation.
