Patent ID: 8469480

Claim:
A method for adjusting a recording substrate and at least one array relative to each other, the recording substrate and the at least one array having a relative position with respect to each other, said array being part of a printing device having a carrying structure for mounting said array and having nozzles arranged in a row substantially parallel to a first direction for forming second test marks on the recording substrate, wherein the recording substrate comprises a pre-printed pattern containing first test marks, the method comprising forming a test pattern by applying the second test marks on the recording substrate, each first and second test mark having a location on the recording substrate; detecting the locations of the first and second test marks; determining a plurality of deviation factors for a plurality of attainable relative positions based on said detected locations, wherein said plurality of attainable relative positions are positions wherein the array and the pre-printed pattern at least partially flank each other, thereby defining a degree of overlap, which positions differ in the number of nozzles falling outside the area of overlap, and each one of said deviation factors is an attribute of a distinct attainable relative position and is indicative of an amount by which distances between neighboring first and second marks deviate from a nominal distance; selecting an attainable relative position among the plurality of attainable relative positions which satisfies a selection criterion applied to the plurality of deviation factors; bringing the array and the recording substrate into the selected attainable relative position; and using the array for printing a pattern while the array and the recording substrate are in the selected attainable relative position.
