What I failed to mention in my earlier reply is why I suggest you look into
using the LightJet 5000 for your prints.
The LightJets can output to conventional photographic materials, such as RA4
and Ilfochrome.
Although not archival, they'll probably last longer than prints from the
Chromapress, which uses toners on press paper.
A couple of places that will do LightJet prints for you are:
1. Laser Light Photgraphics, (508) 799-3996
2. Custom Color Services, Inc. www.customcolorservices.com (800) 300-3686
