A security document printed by a split ink fountain printing device, the security document comprising:
- a first ink layer comprising a first color in a first color zone and a second color in a second color zone offset from the first color zone in a first direction, and a first blended color zone comprising a mixture of the first and second colors, the first blended color zone being between the first color zone and the second color zone;
- and
- a second ink layer comprising a third color in a third color zone and a fourth color in a fourth color zone offset from the third color zone in a second direction, and a second blended color zone comprising a mixture of the third and fourth colors, the second blended color zone being between the third color zone and the fourth color zone;
- wherein the first direction is different from the second direction;
- and
- wherein the first ink layer overlaps the second ink layer on the security document, such that the first blended zone at least partially overlaps the second blended zone producing a blended area of overlap comprising a combination of the first, second, third, and fourth colors.
A security document comprising:
- a first ink layer comprising a first plurality of color zones located adjacent one another in a first direction, adjacent pairs of the first color zones including different colors, and at least one first blended color zone disposed between an adjacent pair of the first color zones, the at least one first blended color zone comprising a first blended color that is a mixture of first and second colors of the adjacent pair of the first color zones;
- and
- a second ink layer comprising a second plurality of color zones located adjacent one another in a second direction, adjacent pairs of the second color zones including different colors, and at least one second blended color zone disposed between an adjacent pair of the second color zones, the at least one second blended color zone comprising a second blended color that is a mixture of third and fourth colors of the adjacent pair of the second color zones,
- wherein the first ink layer overlaps the second ink layer on the security document, such that the first blended color at least partially overlaps the second blended color producing a blended area of overlap comprising a combination of the first, second, third, and fourth colors.
