OK, now that I've used the technical term ...
I want to make my own version of an instant Lottery Ticket. I already have "Predicta" and it's great, but I don't need to do this type of effect--I have another idea and use altogether.
So, I'm looking for a rubber cementy-type substance that is used to make the scratch-off instant lottos. Perhaps this exists in virginal form, or I'll need a recipe. I'm wondering if this is closely guarded secret, but then this is also used on Publisher's Clearing House promos, along with tons of other mass-mail promos, so perhaps it isn't so proprietary.
Does anyone know where to get/how to make this stuff? Also, I'm guessing it needs a certain finish on the paper so it doesn't soak through--that seeems plain.
Any ideas would be helpful.
