Claim One:
1. A method of assessing the quality of a 2-D (two dimensional) matrix type encoded symbol having at least a pair of solid border lines which meet at a right angle; including the steps of: (a) positioning the 2-D matrix type symbol to be imaged by a light sensitive array; (b) displaying an image of the 2-D matrix type symbol on the monitor screen; (c) providing an orientation guide as an overlay for the monitor screen and the 2-D matrix type symbol when so displayed on the monitor screen; (d) providing said orientation guide with a predetermined number of substantially right angle configured guide lines which are parallel to each other to provide chevron-like spaces between adjacent guide lines; (e) positioning said orientation guide so that said guide lines and chevron-like spaces are disposed at least a first rotational disposition when viewed on the monitor screen; (f) orienting the 2-D symbol so as to be viewed on the monitor screen while being so oriented and with respect to the guide lines on the orientation guide, as displayed on the monitor screen, to align a selected solid symbol border of the 2-D symbol with the guide lines and chevron like-spaces of the orientation guide; (g) imaging, and assessing the grade of the 2-D symbol when so aligned; (h) re-orienting the orientation guide and 2-D symbol into a selected number of additional rotational positions and imaging and assessing the grade of the symbol at each such rotational position; and (i) averaging the grades of all the selected positions.
