Try The Lightroom in CA...

I used this company to do some larger prints (30"x40") that I had previously had done on Ilfochrome (Ilfochrome only comes in sheet sizes now)... The customer service and such was fine, but the new LightJet process onto the Fuji Archival Super-Gloss paper is not even close in terms of resolution to the older Ilfochrome prints I still had on hand... Color was an okay match...

The LightRoom is one of the oldest Ilfochrome labs in the country, having printed this photographic process exclusively since 1975. Since 1995, our web site has been providing information on this process to thousands of photographers around the world.
