Abstract
A lottery ticket has game data printed on a substrate in a game data area either directly onto the substrate or onto a covering layer where the game data area is firstly covered by a scratch-off layer which contains a white pigment following which the scratch-off layer is covered by a plurality of layers of ink each of which contains pigment defining different colors for the different layers and which are different from the white pigment of the scratch-off layer so as to form a four color pattern. The scratch-off layer and the inks are sufficiently transparent to view the game data therethrough so that the removal of the scratch-off layer and the inks acts to mark the game data by showing it in a different color from the original view through the layers.
