My folks' studio was just a few blocks away from Luminos headquarters in Yonkers, NY. We did some product shots and graphic arts work for their ads, but our main biz for them was contact printing the
tens of thousands of 4x5 paper samples that they gave out at trade shows.
We did this for years and years, printing identical negs lithographer's taped four-up on an 8x10 in a vacuum frame (actually a NuArc platemaker with the vacuum frame facing up at a point source light on the ceiling), then slicing them apart when dried. The red, green, and other colored-base papers, the texturized papers, the metallic papers. We printed hundreds at a time - they'd drop off whole boxes of the various papers - often as a background task when work slowed down.
My understanding was that over the years they sourced their papers from England, Greece, Germany, Spain... a bunch of European countries. For our own work, we eventually used their Flexicon VC more than Kodak Polycontrast - my dad always said, "With the right filter and exposure, this stuff pops more than the Kodak."
