This is a sample of the "direct color" process we use for prototype dice.
This is on wood cubes, and we are doing the same for plastic dice.
Cheaper than laser etching, and full color available.
Although the sample does not have multiple colors on one side, there is no reason you cannot get a different multicolor image on any number of sides.
Durable, but not as durable as something that is actually laser-etched then inked.
