I'm not sure what actual resolution the transparency adapter scan is yielding, I'm a bit curious (is it scanning with an alpha map as well?)
Not sure if the transparency thing is completely necessary, but if certain ink colors are more transparent than others it does make some sense. (Though I'm not sure mame's artwork system can handle that right now, to be honest! I.E. one additive layer and one screen/mask layer?)
1200dpi 24 bit color to png or lossless tif is how I'd do the scans.
