ABSTRACT:
The rear surfaces of sign component pieces carry printed alignment indicating direction indicia in the form of arrowheads that are of a dark color and have a glossy surface luster while the front surfaces of the pieces carry a printed background of the same color but having a flat surface luster. The direction indicia serve to indicate the alignment of the pieces for proper insertion into a changeable sign and for proper shearing from a large sheet during manufacture. The dark color and glossy surface luster reduce eye strain during the shearing of manufacture.
