What a coincidence - I just reproduced a set of Moulin Rouge plastics, too! I scanned the originals (which were rough but not as toasty as your originals) and cleaned them up in Photoshop. I don't have access to a laser cutter or a direct to plastic printer. I cut and polished the plastic by hand. The images are printed on glossy photo paper with archival pigment inks (no fading in the lifetime of anyone alive today). The images are mounted to the underside of the plastics using optically clear film. A ton of work (especially preserving as much of the tiny details in Photoshop as I could), but rewarding as an overall experience.
