Abstract:
1. A method for verification of the alignment of at least one printing head ( 1 a , 10 a , 1 b , 10 b , 1 c , 1 d ) installed on a printing machine, by linear adjustment of at least one group of points ( 5 ) represented on an image originating from the digitisation of a model comprising a plurality of printed drops ( 4 ), wherein each drop ( 4 ) comprises a plurality of points ( 5 ), each point ( 5 ) having a uniform tint according to a colorimetric database saved in a memory area of a computer system ( 0 ) executing the method and comprising at least one memory space, means for acquisition, recording and processing of data, the method comprising: a. a detection step of the colour of the points ( b. a creation step, by the processing means, of at least one list of points ( c. a creation step, by the processing means, of at least one group of points ( d. a filtering and removal step of groups whereof the number of points ( e. a vectorization step, by the processing means, of at least one group of points ( f. an association step, via the processing means, of each vector ( g. a comparison step, via the processing means, of coordinates of the vectors (
