The only way to do it properly is to get the dials screen printed on.
This will last forever too, as any paper will perish in the car over the years, as will things like overhead projector transperencies and the like.
Not that expensive too. Under a hundred bucks if you know where to go.
Any image/images can be screen printed from a regular jpeg file onto individual dials or onto an instrument cluster. This is how I did mine, can provide pictures if needed.
