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