Secure Lottery Ticket Using Hybrid Construction
摘要:
Solvent-based and water-based scratch-off materials are employed as single layers on a lottery ticket to create a more resistant ticket construction that still provides a satisfactory play experience. In one embodiment, two different scratch-off inks on the play area of the ticket are employed, with the majority of the ink being a softer, solvent-based, formulation. The ink covering sensitive areas of the ticket includes a harder, water-based, formulation.
