Panchromatic b&w paper in sheets
Now that is cool. What differences would I expect to see if I use this paper with color negs in a traditional analog enlarger?

Basically you would gain a b&w print similar to that made on standard b&w paper from a panchromatic b&w negative.
You could also use it as negative acting taking material in a camera instead of negative film.
That is impressive. Similar to Kodak's Panalure? I long lamented it's demise. So would it be possible to control contrast ? I normally use factorial development with FB papers with Dektol.

thank you for helping getting the word out. I'd like to see other people start using this stuff so the availability of cut sheets increases.
I ordered some 810 sheets yesterday--they said they can cut it in other sizes so i'm asking for 11x14 sheets--if you want the other sizes, email them and ask them to cut it up and theyll make put it online for you and everyone else.
I've used this stuff--it's pretty interesting. EI=25 for paper negatives--VERY high contrast
which is why I've found it's best used as EI=12 for direct positive reversal process--look for my other posts on it. It gives a very dramiatic portrait and has about 3 stops faster speed than the ilford direct positive paper. AND it's panchromatic too--which is a good and a bad--you need to handle this stuff in total darkness.
This is the closest thing to photobooth paper that's out there.
color negatives? that color cast in the film--the orange--may give it problems--it may be good for making positives from slides.Then again, that orange may tame the contrast down a bit too. never tried it in the darkroom for printing.
This stuf is more like panchromatic film than traditional darkroom color printing paper.
check ilford's website for what this stuff really is: ilford galerie digital silver paper (RC)--they have exposure information and spectral sensitivity charts on ilford's website.

John, I read your recent posts here but I have no idea what "direct positive reversal process" means. Can you please define it for me ?
it's expose the "film" paper, whatever--in a camera
then you do a standard black and white reversal process: develop, bleach, re-expose and re-develop and fix
you end up with a positive image on the paper or film or whatever was in the camera--if paper, you have a positive image--if film, you have a transparancy for projection or put on a light box to have lit lit from behind.
See the other threads on reversal of black and white film in the bw film paper chemicals section..there are a bunch of people working on this now.
you can also do this with standard photo paper--like ilford multigrade--it's not panchromatic, so you can develop it under safelite--but it's slow--like ei=0.5 or 0.7 slow....
OH--Ilford has a pamphlet on their website about how to reversal process their films--this will work for this paper and other as well.

This might sound rather naive, but if you just used this Ilford Ilfospeed RC Digital directly in the camera why not just develop, (stop) and then fix it ? Why the need to perform a reversal with this paper ???? Surely you will end up with a positive image without reversing it.
