Abstract
A method and system is provided for generating a variable data differential line pattern font comprising forming a periodic line pattern suitable for tessellation disposition within a printed document and selectively distorting a portion of the periodic line pattern in a predetermined manner wherein the distorting comprises generating a distinguishable font corresponding to the distorting. A plurality of different distinguishable fonts are formed by a corresponding plurality of distorted line patterns, respectively.
Claims21
A printer including an electronically stored variable data guilloché pattern for embedding security data in a document printed by the printing system, comprising:
- a base pattern having an exterior portion configured for seamless tilable association in an associated plurality of the base patterns to form the guilloché pattern, and an interior portion comprised of a variable pattern distortion;
- and,
- wherein a plurality of distinctive ones of said variable patterns distortions disposed within a plurality of the base patterns respectively correspond to a set of predetermined template symbols.
A method for generating a variable data differential line pattern font comprising:
- by a printer, forming a period line pattern suitable for tessellation within a printed document;
- by the printer, selectively distorting a portion of the period line pattern in a predetermined manner wherein the distorting comprises generating a distinguishable font corresponding to the distorting;
- and
- embedding the period line pattern inclusive of the selectively distorted portion thereof in the printed document printed by the printer.
