I have a few black and white shorts that are printed on color film stock. All are Derann prints. In general the prints are excellent, although an exact black and white must be very hard to achieve this way. Because of the better resolution of the color film stock, print definition, contrast, and black level are really excellent on all of them. Last night I screened a short B/W film about Pinewood Studios Full Screen Ahead and I noticed a magenta tint to some parts of the film that I had not seen before. This was by no means objectionable, and was only noticeable in a few shots, mainly the opening scenes of the film, but it was a definite change from what I remember when last viewing it. So presumably these black and white prints on color stock will gradually fade to pink, just like regular color prints do.

Paul, I think that would be the case, considering print wise they are actually color films (like other color films too). Only the colors presented are Black and White. So if they are not on low fade stock, any color films will gradually fade to pink/magenta.

Just check any "That's Entertainment" released by Ken Film (most likely on Kodak SP), I guess it would have faded too on B/W section.

Paul,
Low fade prints like 'Full Screen Ahead' - which was a fairly late Derann release - shouldn't be fading before about 2075 at the earliest! Are you certain it has changed since you bought it, as if it has, it has a very rare fault of some kind? One screened at Blackpool looked excellent but I'd guess that the fact that the film has one or two colour extracts could mean that the lab couldn't get as close to pure b/w as might sometimes have been the case.

I've noted occasionally, that some black and white prints, (whether Derann's or not) will have a slightly bluish caste to them, especially if the color stock is L.P.P.
