I have looked at this in the past, even had a go at it myself Hydrographics or HydroGraphics, also known as immersion printing, water transfer printing, water transfer imaging, hydro dipping or cubic printing, is a method of applying printed designs to three-dimensional surfaces. The hydrographic process can be used on metal, plastic, glass, hard woods, and various other materials.
It really has come on in recent times though, the most famous supplier in the UK being Wicked Coatings. They seem to work out a bit more expensive than others although I can't fault their workmanship.
Just a quick post to show a steering column shroud that a friend of mine has recently had done.
