A method of inspecting the quality of blanks () to be processed into packaging material, includes the following steps: A carrier () with a plurality of blanks () is supplied. Each blank () is identified in accordance with its position (n) on the carrier (), and a scanned image (S) of each blank () is obtained, and each scanned image (S) is compared with a reference image (R) associated with the specific position (n) of the blank () from which the image was taken. Based on the result of the comparison, the respective blank () is accepted or rejected. Furthermore, there is a quality inspection system () comprising a digital imaging unit () for scanning images of blanks () on a sheet (), a unit () for generating individual reference images for each blank, a storage () for storing the individual reference images (R), and a comparator () for comparing scanned images (S) of a blank with the individual reference image (R) for this blank ().

Method of inspecting the quality of blanks, in particular of blanks to be processed into packaging material, and quality inspection system

A method for determining the surface quality of a substrate passing from an initial state into a converted state during a conversion process including the steps of acquiring first information relating to surface defects detected on the initial substrate, acquiring second information relating to surface defects detected on the converted substrate, of processing the first information and the second information, and of classifying the converted substrate as a function of the first acquired information relating to the surface defects detected on the initial substrate and as a function of the second acquired information relating to the surface defects detected on the converted substrate.

Method and apparatus for checking the quality of blanks processed with a machine processing blanks of at least a certain type, comprising: carrying out a registering for said possible blank types, feeding a register parameter (n) defining a required number of blanks per pile, loading a pile of blanks into a device, conveying the blanks of the pile throughout a registering area ensuring the scanning of the printing and/or diecutting quality of said blanks, defining which type the registered blank is the better related, stripping the blank if it has printing and/or diecutting defects, and piling up the registered blanks that were not stripped so as to pile up a new pile until it comprises n blanks, and repeating the steps, and apparatus for the foregoing.
