A method and apparatus for aligning the printing of dots generated by at least one array of printing elements in an printing apparatus, wherein the method includes the steps of printing a calibration test pattern, scanning the printed calibration test pattern, determining at least one calibration value based on the scanned calibration test pattern, positioning an alignment adjustment tool relative to the array of printing elements of which the alignment needs to be adjusted and, based on the calculated calibration value, automatically adjusting the alignment of the array of printing elements using the alignment adjustment tool.

Method and apparatus for automatically aligning arrays of printing elements

A printing apparatus () for printing an image on a receiving substrate () including ink application means () for imagewise applying liquid side of the receiving substrate; a drying section () for drying the receiving substrate after the ink application; transportation means () for transporting the receiving substrate along a path () past the ink application mean () and through the drying section (); wherein the path () has a path section () between a first position (P1,P2) at the ink application means () and a second position (P3&#x2013;P7) downstream the first position (P1,P2), the path section () having first () and second () substantially straight portions and a convex curve () between the first () and second () substantially straight portions.
