Abstract

A method of producing a lottery ticket and lottery tickets produced thereby wherein an overprint region is provided over at least a scratch-off layer, the overprint region comprising an image obtained from a design in which the colors in the design have been separated into half tone images of each color and are superimposed on at least the scratch-off layer of the lottery ticket.

Claims

1. A method of producing a lottery ticket comprising:

(a) applying printed indicia on a substrate;

(b) covering at least a portion of the printed indicia with a scratch-off layer; and

(c) applying an overprinting layer over at least the scratch-off layer, said overprinting layer comprising an image obtained from a design in which four colors in the design have been separated into screened half tone images of each color and then said images are superimposed in separate printing steps to form said overprinting layer.

2. The method of claim 1 wherein the colors are yellow, magenta, cyan and black.

3. The method of claim 1 wherein the colors are yellow, green, cyan, magenta, orange, and black.

4. A lottery ticket produced by the process of claim 1.

7. A lottery ticket produced by the process of claim 1.

10. A lottery ticket produced by the process of claim 1.

5. A method of producing a lottery ticket comprising:

(a) applying printed indicia on a substrate;

(b) covering at least a portion of the printed indicia with a scratch-off layer; and

(c) applying an overprinting layer over at least the scratch-off layer, said overprinting layer comprising an image obtained from a design in which six colors in the design have been separated into screened half tone images of each color and then said images are superimposed in separate printing steps to form said overprinting layer.

6. The method of claim 5 wherein the colors are yellow, green, cyan, magenta, orange and black.

8. A method of producing a lottery ticket comprising:

(a) applying printed indicia on a substrate;

(b) covering at least a portion of the printed indicia with a scratch-off layer; and

(c) applying an overprinting layer over at least the scratch-off layer, said overprinting layer comprising an image obtained from a design in which seven colors in the design have been separated into screened half tone images of each color and then said images are superimposed in separate printing steps to form said overprinting layer.

9. The method of claim 8 wherein the colors are yellow, green, cyan, magenta, orange, blue or purple and black.
