The paper was Kodak's Panalure. The original wasn't that great, and even the H contrast (Hard) was a bit soft. The later version, Panalure Select RC, was actually quite good and the S, M, H grades seemed accurate. I liked it and have a few prints on it that I still like. I wish someone would make such a paper again. It's just a black and white paper that's panchromatic. It has to be handled in either complete darkness or under a dim safelight made for color paper. I used it with my Duka 50 sodium safelight set for RA4 paper and never had a problem with that.

Graded paper is even worse since its sensitivity is even more limited.
Hey Simon - could Ilford make a good panchromatic paper for this, please?
Probably the best way to do this and get good tonality might be to print onto film and reversal process for a negative, then print that. You could reversal process black and white or, heck, just use E6 if some filter experimentation could eliminate any color cast. A slight cast wouldn't hurt much, as long as it wasn't too red.
