Abstract:
A method of collecting and processing 2-dimensional image data values to enable an evaluating of a print quality of a data carrying graphical symbol contained within the image data, the method comprising the steps of:a) collecting a plurality of data values, each data value representative of a level of reflectivity of an associated spatial image position within a 2-dimensional image; b) determining virtual scan paths along desired paths, which traverse selected portions of the graphical symbol at a selected orientation; c) extracting a plurality of the data values associated with each determined virtual scan path, wherein each plurality of data values is representative of at least portions of a digitized virtual scan reflectance profile signal; d) processing the plurality of extracted data values of each virtual scan reflectance profile signal to provide at least one figure of merit indicative of the print quality of the imaged data carrying graphical symbol.
