As far as I know Gary Auerbach - search website under that name - palladium/platinum workers recommend contact printing.

Calumet sells "Kodak Professional B/W Duplicating Film " Quoting: " Orthochromatic, medium contrast, direct positive film for one-step duplication of black & white continuous tone black & white negatives. Contrast can be manipulated to save problem negatives."

You need to be *serious*, though: 25 sheets of 8x10 is $133.00!!

I did use this once upon a time to make large negatives for gum-bichromate printing. Its speed, etc., is similar to paper.

Good luck!

Purists will scream, but think digital. You can scan any print ---which of course may be a heavily manipulated image---and produce a negative transparency of any size you wish. This is your contact neg for P&P printing.

Almost all p/p printing is done by contact printing. This means making an 8x10 negative either, as suggested, on direct reversal film, or by use of an internegaive. In theory, it is possible to use an enlarger modified for the use of UV light sources. Unless you are a "techie" with access to good test equipment, it really isn't worth it. You need a UV source such as a sodium lamp, which provides enough UV, which requires modification to most enlarger housings, but then you lose lots of it in most enalrger lenses. Not to mention the heat problem, or the danger if you are exposed to too much UV, etc., etc. If I ever get the money to get the gear, and have the time I might try it - including testing lenses to see which have the least loss. But it's way down on the priority list. In general, I suggest doing the enlarging at the negative creation stage and contact print.
