Abstract
An inkjet printer comprises a transport mechanism () for transporting a substrate along a first axis, a print engine () comprising at least two inkjet print bars () arranged along the first axis, and a controller for controlling the ejection of ink by the at least two inkjet print bars. It further comprises at least two first encoders for the determination of at least two first positions of substrate locations along the first axis and a compensation module for processing the at least two determined first positions to generate at least one first individual compensation parameter for each of the at least two inkjet print bars (). The first compensation parameters are transmitted to the controller to influence the ejection of ink in such a way that effects due to variations of the at least two first positions of the substrate along the first axis are compensated. The effects of positioning errors that may affect different print bars () arranged along the longitudinal axis of the print engine () differently may be compensated using the encoders, individually for the different print bars ().
