Abstract:
1. A method of printing and validating a lottery ticket at a point-of-sale terminal, comprising: providing a stock paper to the terminal, the stock paper having a first defined inkjet printing section, and a second defined section having a thermally sensitive ink composition applied thereto; at the point-of-sale terminal, printing an individual lottery ticket on the stock paper, including printing game data and related indicia on the first section with an inkjet printer; for each ticket presented as a winning ticket, forming a permanent and continually visible validation mark on the ticket by exposing the second section of the stock paper to a heat source to activate the thermally sensitive ink composition, such that the validation mark remains visible on the lottery ticket to show that it has been submitted for validation; forming the second section by coating the stock paper with the thermally sensitive ink composition in the second section, and applying a protective coating over the coating of thermally sensitive ink composition; and wherein the thermally sensitive ink composition is applied to the second section as a pattern or indicia that is exposed to a uniform heat source such that the validation mark appears as the originally applied pattern or indicia.
