摘要
A negotiable document includes enhanced security for deterring the fraudulent photocopying of the subject negotiable document. A first pantographic design is imprinted as the general background of the front face of a check and a second pantographic background design is imprinted in the amount line and in the signature line. The enhanced security document of the present invention further includes a muted warning phrase of a first dot size incorporated in the first pantographic design and a muted warning phrase of a second dot size incorporated in the second pantographic background design. Alternatively, it will be understood that a similar warning phrase may be generated with a different first and second size dot density or line density instead of a first dot size and a second dot size. By using a plurality of line densities, or dot densities, or dot sizes for the warning phrases, an unauthorized individual will be unable to adjust a photocopier to mask a single warning phrase.
