Abstract

A printed security-enhanced document, printing method, and system for ensuring that any printing defects present in the variable indicia also occur in the background on the document protected. By ensuring that random printing defects in the variable indicia also appear in the same document's background, detection of the printing defects becomes more readily apparent.

First claim

What is claimed is:

1. A lottery ticket comprising:
a substrate having opposing side edges and opposing end edges;
first variable indicia printed on a first area of the substrate, the first variable indicia comprising a plurality of different component colors printed by a printer;
second variable indicia printed on a second area of the substrate adjacent to the first variable indicia, the second variable indicia comprising the plurality different component colors except for a first one of the component colors of the plurality of different component colors due to a component color printing error by the printer;
a first background printed on the substrate in a third area of the substrate adjacent to the first variable indicia and extending outside a border of the first area, the third area being in a first straight line on the substrate with the first area, the first straight line being parallel to the side edges of the substrate, the first background comprising: (a) the plurality of different component colors, and (b) an additional component color not present in the first variable indicia or the second variable indicia, wherein the additional component color is different than each of the plurality of different component colors, wherein the plurality of different component colors and the additional component are configured to form background artwork in the third area, wherein for each of the different component colors of the first variable indicia, the first background comprises a same corresponding component color printed by the printer at a saturation level of at least 5%;
a second background partially printed on the substrate in a fourth area on the substrate adjacent to the first background and adjacent to the second area and extending outside a border of the second area, the fourth area being in a second straight line on the substrate with the second area, the second straight line being parallel to the side edges of the substrate, the second background comprising: (a) the plurality of different component colors except for the first component color due to the same component color printing error by the printer, and (b) the additional component color not present within the first variable indica or the second variable indicia, wherein the plurality of different component colors and the additional component color are configured to form background artwork in the fourth area, wherein the component color printing error is a continuous component color printing error caused by the printer for the second variable indicia and the second background; and
a scratch-off coating covering the first variable indicia and the second variable indicia;
wherein the second background is not covered by any scratch-off coating.

2. The lottery ticket of claim 1 , wherein the continuous component color printing error is a process color misprint.

3. The lottery ticket of claim 1 , wherein the additional component color of the first background and the second background that is not present in the first variable indicia or the second variable indicia is printed with a saturation of less than 5%.

4. A lottery ticket comprising:
a substrate having opposing side edges and opposing end edges;
variable indicia printed on a first area of the substrate, the variable indicia comprising a plurality of different component colors printed by a first printer;
a background printed on a second area of the substrate adjacent to the first area and outside of a border of the first area, the background comprising: (a) for each of the plurality of different component colors of the variable indicia printed by the first printer on the first area of the substrate, a same corresponding component color printed by the first printer at a saturation level of at least 5%, and (b) an additional component color not present in the variable indicia printed with a saturation of less than 5% by the first printer, wherein the additional component color is different than each of the plurality of different component colors, wherein the first plurality of different component colors and the additional component form background artwork in the second area,
wherein the plurality of different component colors of the variable indicia printed by the first printer and the additional component color are all aligned in a straight line parallel to the side edges of the substrate such that a continuous printing error by the first printer of not printing a first one of the component colors of the plurality of different component colors in the first area would extend in a straight line parallel to the side edges of the substrate into the background on the second area but would not affect the additional component of the background; and
a scratch-off coating covering the variable indicia.

5. The lottery ticket of claim 4 , wherein a portion of the background is not covered by the scratch-off coating.

6. The lottery ticket of claim 4 , wherein the background is covered by the scratch-off coating.

7. A lottery ticket comprising:
a substrate having opposing side edges and opposing end edges;
variable indicia printed on a first area of the substrate, the variable indicia comprising a first plurality of different component colors printed by a first printer;
a scratch-off coating covering the variable indicia; and
a display background printed on a second area of the substrate that is outside of a border of the first area, the display background comprising: (a) for each of the first plurality of different component colors of the variable indicia printed by the first printer, a same component color printed at a saturation level of at least 5% by the first printer in a straight line with said component color printed by the first printer in the first area, and (b) an additional component color not present in the variable indicia printed with a saturation of less than 5% by the first printer in the straight line, wherein the additional component color is different than each of the first plurality of different component colors, wherein the straight line is parallel to the side edges of the substrate, wherein the display background is not covered by any scratch off coating, and wherein a continuous printing error by the first printer of not printing a first one of the component colors of the plurality of component colors would extend from the variable indicia into the display background and would not affect the additional component of the display background, and wherein the first plurality of different component colors and the additional component form background artwork in the second area.
