Prints turning brown?

RalphLambrecht · Aug 31, 2014

exposure to light before fixing/processing errors with RC are rare.

Seems to me it wasnt fixed at all. After a stop and wash, the paper will slowly go brown with hues...

Would this be a slow process? I'd have thought that if there was no fix the problem would be apparent after 12 hours but the OP says it wasn't.

The OP originally printed on 29 Aug so we are now nearly 6 days on. It might be interesting to find out what has happened since

OP, has there been any changes since you first noticed the brown effect on 30 Aug?

Thanks

That's good to know. One more thing I'll watch for from now on. Thanks.

with RC, I trykeep my totalwet time under 10 minutes.above that, edges may start to peel off, which isn't necessarily a coomplete disasterbecause, in most cases ,they rejointhe substrate nicelywhen drying

Yes it's a slow process. And if the print is in the dark, the process becomes extra slow to almost none. The degree of this phenomenon also depends on the paper itself: incorporated-developers vs. non-incorporated developers.

I saw his attached photo. It's on the edges. My theory can still be be valid, especially if the prints were stacked. The light would only hit the edges.

Also, his attached example reminds me more of print stains that one can get on prints going from the developer to the fixer... So who knows, really.

Maybe the fixer wasn't actually fixer. An error of bottle selection perhaps?

I just saw the new responses to this thread this morning. I'll check the prints when I get home tonight and let you know.

If the prints were not fixed wouldn't the brown be in places other than the boarder?

The prints were fixed and since I made it up from the last of the stock I had (only photographers formulary bottle I have aside from PMK) I'm completely sure I didn't use the wrong bottle.

I can see missing one print in the fix or not leaving it long enough (if you were somehow distracted) however this didn't just happen with one it happened with all the prints I made in that session.

Well that's why, if it happened on all the prints, the problem might be with either ALL of the papers or ALL of the fixer.

The prints look just like when I scanned the example. No more browning since.

How old is the paper, i.e how long since you last printed some from that box? I just printed the other night from a box that has been sitting on my shelf for, erm, 5 years. Top sheet had browned edges, the second sheet was fine. Undeveloped paper is damaged by low concentrations of some air pollutants, particularly sulfur-containing, and it will perfuse even into a closed bag+box. If you store paper in the same cupboard (or even room maybe) as fixer or some toners, you can expect problems.
