    Just finished washing fibre prints, after the final wash I noticed a brown mark on the paper. I think it might be from the siphon when washing. Anyway to remove these marks??

    Brown spots on prints? Do they look suspiciously like fingerprints? Nine times out of ten, these sort of marks come from carrying active developer over into the fixer on either your fingers or tongs.

    I often get gunk on prints from an incomplete washing, caused by washing in static water in a community darkroom.

    Try re-fixing, it is possible your fixer is partially exhausted.

    Have a good read about archival processing and two bath fixing, this helps eliminate problems like this with FB papers. Welcome to APUG BTW.

    I sometimes get brown marks from residue in the tray I use for washing. Is your wash tray squeaky clean?

    If they are thin brown lines, and you are washing a number of prints at once, there is a good chance they are just scum marks. Try rubbing lightly with a clean finger when the print is wet. If they are splodges then it could be cross contamination of some sort. I would refix and rewash in the first instance.

    Thanks, I did read about 2 bath fixing. Will try that next time. I'm thinking the problem might be with our water supply, odd days they flush the lines and there is sediment in the water. I will try the rewash and refix with fresh fix.

    New Question How can I compensate for overdeveloped negative when printing? My developer concentrations were too strong. Oopps!

    You could try split grade printing on VC paper. This would allow you to manipulate the tones. There are threads on this site regarding split grade printing. An other option would be to use a superproportional reducer on the negatives.

    Dian, In future this question might have been posted as a new thread. It is quite different from the original OP. It also is probably of interest to many others.

    Regards
