(54) A bookbinding machine with improved sequencing error identification


(57) A method for identifying signatures in a bookbinding machine is proposed. The method includes the steps of: providing (404-418) a representation of each signature of a predetermined sequence to be repeatedly processed by the bookbinding machine, for each cycle of the bookbinding machine involving the processing of a current signature, acquiring (404-405) a digital image of the current signature, comparing (420-424) the digital image of the current signature with the representation of an expected signature in the sequence, in response to a negative result of the comparison of the digital image of the current signature, comparing (448-458) the digital image of the current signature with the representation of at least one signature being adjacent to the expected signature in the sequence, and identifying (460) the current signature according to the results of the comparisons of the digital image of the current signature.
