Abstract: In an ink jet printing method, a recording medium is moved relative to a print head having a plurality of nozzles, and ink droplets are ejected from the nozzles onto the recording medium in a single pass in accordance with print data supplied to the print head. Spit pattern data is included in the print data A location of an expected ink dot ejected according to the spit pattern data is scanned, providing a scanned image, and such ink dot is searched for in the scanned image in order to determine an actual presence of the ink dot.

Abstract: A reproduction apparatus for printing a digital image includes a control unit and a print engine. The digital image is constituted of pixels, each having assigned a pixel value. The print engine includes print elements for ejecting an amount of marking material on a receiving material according to a pixel value. The reproduction apparatus includes a detector for detecting a failing print element and the control unit includes a derivation unit for deriving, before printing of the digital image for a print element, at least one array of pixel values to be printed by at least one other print element, upon detection of a failing of the print element by the detector. A merging unit is configured to merge at least one of the at least one array of pixel values with the digital image, upon detection of a failing print element, for creating a corrected digital image.
