    The material on scratch cards and lottery tickets is a latex ink. This ink is applied to printed material. A non-porous surface like enamel paper is used. The paper must then be coated with a release coating of varnish. After a release coating has be applied the scratch off material is then applied. Different processes take from 1 to 11 coats depending upon desired design, colors, and opacity for security. This material can be applied with an offset printing press, flexo, or using a silk screen process. One of the largest provider of scratch off cards in the world is ImpactWorldwide.com.

    There is a special ink, called "scratch off ink." It is "an opaque printing ink formulated to be applied on a substrate to hide the information already printed on the substrate and to be scratched off to reveal the printed information." (www.aqmd.gov)

    "Substrate" just means a piece of paper or cardboard or whatever the ink is printed onto. Sub = "under" and "strate" = layer. So the substrate becomes the "under-layer" once it's covered with scratch off ink.

    The ink dries into an opaque film, that is scratch-off-able.

    There's a really detailed article about how to prepare these inks at:
