Abstract: According to one example, a printer includes an inkjet printhead, and the printhead comprises nozzles through which printing fluid is ejectable during a pass of the printhead across a print zone. Processing printhead control data includes obtaining printhead control data describing pixel locations in an image to be printed on a media, and allocating, for a swath of the image, each of the pixel locations to a printhead nozzle and to a print pass of a set of print passes in accordance with a print mask. The print mask defines sections associated different groups of the nozzles.

Abstract: A method of digital printing is disclosed in which a digital image to be printed has at least one region having pixels comprising superpositioned layers of a first ink and a second ink. The method includes producing at least one sample print and calibrating misalignment of the superpositioned layers at a plurality of calibration locations on the sample print. The resultant misalignment data is provided to a morphing program to pre-deform the digital image to provide a modified digital image which compensates for misalignment during printing. The image is then printed using the modified digital image. An apparatus and a machine readable storage medium comprising instructions executable by a processor are also disclosed.

Abstract: Method and devices for dynamically preventing printing errors caused by a media deformation are disclosed. In one example, a pen to print media space (PPS) distance is measured. A media deformation is identified in response to measuring the PPS distance. A corrective function is identified in response to identifying the media deformation. The corrective function identified is then performed. The proposed method provides for consistent quality across a print.

Abstract: Methods performed by a printing system are described herein. A portion of a print area is located by operating an optical sensor to respond to a color shift. The color shift is from a printed reference color. The color shift is caused by a fixer fluid applied to the portion. Printing systems and tangible machine readable storage mediums are also described herein.

Abstract: An apparatus and method for controlling a printing device are described. In examples, a printing device has a first printhead interface, a first printhead for use in applying a treatment fluid to a print medium and a second printhead interface, a second printhead for use in applying ink to the print medium. The first and second printhead interfaces are consecutively aligned along a common axis and each printhead has a plurality of nozzles that extend in a direction of relative movement of the print medium in relation to said printheads. An example apparatus then has a controller arranged to, when the printheads are installed, configure activation of nozzles of at least one of the first and second printheads in the direction of relative movement to spatially offset useable nozzles of the first printhead with respect to useable nozzles of the second printhead in said direction.
