Manual rotation of the symbol is viewed on the monitor screen as the symbols solid line border is moved into alignment with a guide line at which time the symbol is imaged and its quality graded. Display of the orientation guide in at least five selected rotational dispositions, alignment of the symbol solid line border therewith and imaging and grading of the symbol quality in each such position provides multiple grade scores for averaging into an overall grade score.
