  • Cards having variable benday patterns
    Patent number: 5769458
    Abstract: Alternative benday patterns for cards and tickets and methods of producing such patterns are disclosed. The alternative patterns enhance the effectiveness of conventional devices by avoiding use of rotating print cylinders, with fixed repeats, in their creation. The attendant reduction in, or elimination of, benday repetition inhibits vertical ticket splitting and other manner of compromise. Desired images, including play indicia, promotional content, or both, can also be visibly encoded in the benday patterns, if desired.
