Out of curiosity, what is the scanning procedure? If the original is 7x17, what kind of scanner can chew on this big of a negative?

I used to have a tabloid-size Microtek scanner. When it died/was software-orphaned I replaced it with an Epson V-750 Pro. Much better in resolution, tonal range, and software controls. The negative has to be scanned in two bites, but that's just a bit of nuisance. I pick which end to analyze in prescan, then lock down the controls and do the two halves without touching any controls. Merge the halves in PS using Photomerge, "position only"—if you merge on the defaults, the software may invent all sorts of non-existant perspective problems to solve. Another trick is to scan with the emulsion side down. That's opposite of what you are supposed to do, but the less shiny emulsion side of the film is much less likely to have Newton ring trouble. Just flip the resulting pair of files in the PS rotation dialog.

What are you printing the negative on? I presume it is something other than OHP transparency as that does not take the ink at sufficient density

Paul, I use a material called Fixxons, originally intended for silk screen work. It handles a huge ink load and has very low UV blocking (the equivalent of fb+f in film) so it can carry a very long density scale. Many people use Pictorico products, but they are much more expensive and I haven't found them to be any better, partly because they have a much higher base density for UV.
