ABSTRACT:
Coding of a group of characters for recognition by a machine and by a human viewer is provided by coloring each character with a predetermined plurality of colors arranged in predetermined locations within a character configuration. Each character configuration in a set of characters is segregated into a plurality of sectors and each sector is coded by a predetermined one of a plurality of colors which differs from the color coding of an adjacent sector. Apparatus for forming the color-coded characters by printing and by a photoelectrophoretic process is disclosed. Apparatus for automatically recognizing characters colored according to the predetermined code comprise color detecting elements positioned in an array at a reading station for generating output electrical signals representative of the color-sector coding and circuit means coupled to the detection means for translating the color-sector signals into an electrical signal representative of a character in a set.
