A method for producing scratch-off lottery tickets in a high speed printing line is provided, wherein the printing line includes one or more inkjet printing machines that print lottery tickets on a continuously running paper stock. One or more primer layers are applied to a surface of the paper stock in a defined game play area on each lottery ticket. With the inkjet printing machines game play indicia is printed over the primer layers in the game play area on each lottery ticket at a resolution of at least 600 dpi. The running paper stock is conveyed through the inkjet printing machines at a rate of at least 950 ft./min. The ink jet printing machines use a specially formulated dye-based ink.

System and method for printing scratch-off lottery tickets

Lottery tickets are printed and validated ('branded') at a point-of-sale terminal by 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, the individual lottery tickets are printed 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, a validation mark is formed on the ticket by exposing the second section of the stock paper to a heat source to activate the thermally sensitive ink composition.

An energy cured coating is described that may be used in numerous applications. In one embodiment, for instance, the coating can be used as a seal coat layer in a gaming card. In particular, the coating can be used to protect a hidden printed layer that is covered by a scratch-off material. In accordance with the present disclosure, the cured coating contains at least one monomer or oligomer in combination with a reactive plasticizer. The plasticizer may comprise one or more benzoates.

Energy cured coating

A scratch off lottery game card including a substrate on which a plurality of game indicia are printed on the substrate and a layer of translucent thermal ink coating is placed upon the lottery game card covering the game indicia. The translucent thermal ink coating changes its color when heat is applied, typically from the player scratching the game indicia.
