A method for manufacturing a printing bar unit 2 for a printing system, comprises the steps of providing a support bar 5 having a plurality of primary mounting positions, providing a plurality of exchangeable printheads 9 having a plurality of inkjet nozzles, and releasably mounting the printheads 9 to the support bar 5. Preceding the step of releasably mounting the printheads 9 to the support bar 5, a plurality of reference organs 7 are connected at the primary mounting positions to the support bar 5 and undergo an alignment finishing process for forming a plurality of accurate secondary mounting positions 7a, and then in a subsequent step the printheads 9 are releasably mounted to the secondary mounting positions 7a on the reference organs 7. A dimensional tolerance of the secondary mounting positions 7a on the reference organs 7 relative to each other preferably is more accurate than a dimensional tolerance of the primary mounting positions on the support bar 5 relative to each other. |
