As a stick-on scratch-off label in almost any colour. A good 80% of all Pantone colours can be produced as scratch-off labels. Multicoloured versions are also possible, for example to add text or a logo or even a photography.
For direct printing on paper, i.e. for the production of larger quantities of scratch-off tickets, the standard colours are silver and gold. With somewhat longer lead times for industry-side mixing and minimum quantities, there are also black and white scratch-off inks as well as some coloured shades.
