Scanning inkjet printing assembly

Abstract

A scanning inkjet printing method comprises arranging a recording medium on a print surface; moving a carriage supporting at least one inkjet print head over the recording medium on the print surface in a scanning direction, while image-wise applying droplets of a liquid to the recording medium to form a first swath of printed dots on the recording medium; moving the recording medium and the carriage relative to each other in a transport direction, wherein the transport direction is transverse to the scanning direction; moving the carriage over the recording medium on the print surface in the scanning direction, while image-wise applying droplets of the liquid to the recording medium to form a second swath of printed dots on the recording medium; detecting a position of the first swath; determining a sub-carriage movement relative to the carriage in response to the detected position of the first swath to position the second swath relative to the first swath, wherein the sub-carriage is supported by the carriage and the movement comprises an amount of translation in the transport direction transverse to the scanning direction and an amount of rotation around a rotation axis, wherein said rotation axis is perpendicular to the print surface; and moving the sub-carriage in accordance with the determined amount of translation and the determined amount of rotation. Thus, the first and the second swath may be positioned accurately adjacent to reduce visibility of stitching inaccuracies between adjacent swaths.
