20110069105 | ADJUSTMENT OF A PRINT ARRAY AND A SUBSTRATE IN A PRINTING DEVICE - A method for adjusting a recording substrate and at least one array relative to each other, the array being part of a printing device having a carrying structure for mounting the array. The array has nozzles arranged in a row substantially parallel to a direction for forming second test marks on a recording substrate, the substrate being pre-printed with first test marks. The array and the recording substrate are in an attainable relative position. The method comprises forming a test pattern having the first and second test marks and 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 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; and selecting an attainable relative position among the plurality of attainable relative positions which satisfies a selection criterion applied to the plurality of deviation factors. | 03-24-2011 |
