hydro dip graphics

[swel304]

Been wondering about this for a while and cant seem to find anyone who can tell me. Can a disc be painted this way without making it illegal? http://raindancehydrographics.com/index ... &Itemid=84
As I understand it the paint is actually dye and I know that on anything we have dipped like this there was no detectable thickness too it. Anyone know if this is how dcraft/innova are making the full color discs, or are they using some kind of sublimation or screen printing?
