The manufacturer says not to use anything but a red safelight
but I thankfully didn't have any problems with the OC lights.
Also, how are you agitating the paper? One cause of dichroic fog, which sounds like what you may have, is aerial oxidation, so if you agitate by flipping the prints in the tray, or if you're processing in a rotary tube, that would explain it. Older style papers are more prone to this than modern papers.
That's strange. It's possible you got a bad batch. I usually agitate gently for the whole development time by a combination of rocking the tray and rotating the print. I start the print face down and flip it once after about a minute, and usually process 3 min in amidol or 2-3 min in 130, 1 min. rinse, then 1 min. TF-4.
I have also done what you have described above, looks like we have the same methods. I'm thinking it is a bad batch of paper. I don't think EMAKS stamps a lot number on there paper packs do they?
It's the fact that you don't use an acid stop bath that raises a question with me. A water stop is fine if you can use a lot of water. If you're just re-using water in a tray, before long that water stop tray becomes a tray of very dilute developer. You might be carrying enough active developer over into the fix to cause just this sort of problem. I'm not familiar with Emaks paper. Maybe this problem started after you'd run more than a few prints through the water stop tray without having changed out the water?
I've been using Delta 1 Bright Lab Jr. red safe lights. Are these red and dim enough?
I used to have one, and it was usually OK with graded papers, but you've got to test it for yourself in your darkroom. These days I use a combination of LED safelights and a Thomas Duplex and a lot depends on things like safelight distance, ceiling height, and such, so you need to run some tests.
