Abstract
A full-color protected document, and methods and systems for making same, secured by a removable Scratch-Off Coating, where the protection against document alteration and/or copy type attacks is provided by digitally imaging Benday patterns and/or digital imaged background patterns around the variable indicia. By printing Benday patterns and/or imaged background using the same process color imagers, usability and integrity of the protected document are achieved relative to the consumer's perspective while at the same time providing a more secure, less expensive, and more aesthetically pleasing document design.
Claims14
A plurality of lottery tickets for a single lottery game, the plurality of lottery tickets comprising:
- a first lottery ticket comprising:
- a first substrate;
- a first background imaged on a first area of the first substrate;
- first variable indica imaged on a second area of the first substrate;
- a first Benday pattern with a first rotational anisotropy imaged in the first background, the Benday pattern printed in a first rotational orientation;
- and
- a first scratch-off coating covering at least a portion of the first and second areas of the first substrate;
- and
- a second lottery ticket comprising:
- a second substrate;
- a second background imaged on a first area of the second substrate;
- second variable indica imaged on a second area of the second substrate;
- a second Benday pattern with a second rotational anisotropy imaged in the second background, the second Benday pattern printed in a second rotational orientation, the second rotational orientation being different than the first rotational orientation, wherein the second Benday pattern is a same pattern as the first second Benday pattern;
- and
- a second scratch-off coating covering at least a portion of the first and second areas of the second substrate.
A plurality of lottery tickets for a single lottery game, the plurality of lottery tickets comprising:
- a first lottery ticket comprising:
- a first substrate;
- a first background imaged on a first area of the first substrate;
- first variable indica imaged on a second area of the first substrate;
- a first void pantograph comprising a first Benday pattern with a first rotational anisotropy imaged in the first background, the void pantograph printed in a first rotational orientation;
- and
- a first scratch-off coating covering at least a portion of the first and second areas of the first substrate;
- and
- a second lottery ticket comprising:
- a second substrate;
- a second background imaged on a first area of the second substrate;
- second variable indica imaged on a second area of the second substrate;
- a second void pantograph comprising a second Benday pattern with a second rotational anisotropy imaged in the second background, the second void pantograph printed in a second rotational orientation relative, the second rotational orientation being different than the first rotational orientation;
- and
- a second scratch-off coating covering at least a portion of the first and second areas of the second substrate.
