Greetings -
The following is true of both colour stocks and B&W stocks.
All camera negative film stocks are extra low contrast (to capture the big range of tones of a scene).
The projection positive stocks used to make positive prints from those low contast originals are always extra-high contrast stocks.
They kick up the negative's low contrast so it has a "good" contrast on the screen.
Also:
B&W Camera negative stocks (Plus-X and Tri-X) have a grey layer built into the plastic base. Can't be washed out.
In the camera, this absorbs the light of extra-bright parts of the image so it doesn't "halate" - make glowing rings around lightbulbs in the picture.
If you were to project a print made on these camera stocks, that grey plastic base would hold back some of the total light and make the picture dimmer than if you'd used a regular print stock.
Regular print stocks receive only very careful exposure in the lab, so grey plastic isn't needed to absorb excess light.
So print stocks have transparent plastic bases, and all the projection light shining through the bright parts of the image, winds up on the screen.
What to do, if you want to make projection prints from B&W Plus-X or Tri-X?
Print it on (high contrast) colour positive print stock, (see intro sentence at start.) even though there's no colour.
It will kick up the B&W contrast just as the B&W stock would have done that.
But, you may not get a totally neutral grey scale; the image may wind up bluish or brownish, etc.
Discuss with your lab maven.
One more: sound track stocks are high contrast stocks, but they might have a grey plast base also.
So the resulting prints might have a "good" contrast, but they'd be dimmer than usual.
