The two methods that would I think work best for art reproduction are waterslide decals and/or dry transfer decals.
The waterslide decals can be tough because you really need a white base to reproduce all the colors correctly. Whether that means you can print the white base using white ink(which is VERY rare), or you print on a white decal sheet, which when cut out, can result in the white cut edges showing. Color matching can be tough with these because the factory typically used standardized Pantone Spot colors and most home model printers can't hit these colors with 100% accuracy.
The dry transfer decals work extremely well and look damn good. They can also be made by companies that use those Pantone Spot colors and can hit them perfectly. But, they're a one and done kind of thing. You only get one shot to place them once you start rubbing them into place. You really have to be sure of your location. This can be worked with and there can be ways developed to make sure you place them just right. Plus, they can be really expensive. You'd have to get a very large sheet and cram as many sets on there as possible to bring down your per game cost.
But before you even get to that part, the reproduction of the artwork can be very time consuming to do it the proper way. Depending on complexity, it could be anywhere from 10-40 hours worth of work just to get it dead on AND in a state that is print-ready.
You can see how the cost really starts to add up with doing these. PPS most likely has the artwork and the original screens to most, if not all, the big B/w titles we'd all want/need. If there's anybody who can start doing these with some of the harder steps already taken care of, it'd be them. But again, they're probably not interested in doing quantities less than 500 or so for each title, and that's not likely to happen, even with TAF.
