Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
A printable substrate for encoding and readout of coded ink symbols, comprising a substrate and a plurality of repetitive patterns thereon, each such pattern consisting of at least four discrete areas each area having an ink of one coded ink component which emits radiation in a predetermined wavelength range on irradiation with a shorter wavelength radiation, each predetermined wavelength range being different from the wavelength range of the radiation from any other discrete area in the pattern repetition, said substrate being adapted to have certain portions of said repetitive patterns blocked out to encode it in accordance with a predetermined information code, thereby permitting simultaneous reading of a plurality of components in a pattern by wavelength discrimination, to read out said encoded ink symbols.
Claim 2
Dependent Claim
124 words
A printable substrate for encoding and readout of coded ink symbols, comprising a substrate and a plurality of repetitive patterns thereon, each such pattern consisting of at least four discrete areas each area having an ink of one coded ink component which emits radiation in a predetermined wavelength range on irradiation with a shorter wavelength radiation, each predetermined wavelength range being different from the wavelength range of the radiation from any other discrete area in the pattern repetition, said substrate being adapted to have certain portions of said repetitive patterns blocked out to encode it in accordance with a predetermined information code, thereby permitting simultaneous reading of a plurality of components in a pattern by wavelength discrimination, to read out said encoded ink symbols.
Claim 3
Dependent Claim
22 words
A substrate according to claim 1 in which the printable substrate is paper, and the repetitive pattern is a pattern of stripes.
Claim 4
Dependent Claim
22 words
A substrate according to claim 2 in which at least one of the photoluminescent components is a chelate of a lanthanide ion.
Claim 5
Dependent Claim
24 words
A substrate according to claim 2 in which means are provided for accurate registration of the stripes on stacked sheets of the paper substrate.
Claim 6
Dependent Claim
19 words
A method for processing information which comprises encoding the substrate of claim 1, and thereafter reading said encoded substrate.
