ABSTRACT:
A method of printing modules for a two dimensional barcode that includes printing a pixel at a plurality of the pixel locations included in the inner portion of the darkened module, and printing a pixel at less than all of the pixel locations of the outer boundary of the darkened module. Various embodiments are contemplated, such as, without limitation, methods that print darkened modules having four light corners, three light corners, two light corners, one light corner, and/or one light edge. Also, a method of printing a two dimensional barcode having a finder pattern wherein the inner edge of the finder pattern is light, meaning that is does not include any printed pixels at the pixel locations along the inner edge.
