    I am bidding on a Paterson RC washer as we speak . I didn't know they could be used for Fibre. I will look more into this. It might be a good intermediate step to FB papers without shelling out the extra on a dedicated washing system. I had looked at the Nova upright models which look like the way I would probably go.

    I will try the magnet idea and if this doesn't solve the problem of the paper curl I will contact Ilford about it. I can always use the curly paper for contact sheets

    You are correct for fibre, but I thought we were discussing R/C paper here. Since the paper is encapsulated it shouldn't absorb much mosture.

    Mark, considering Sparky's comment again, are you sure that the warm tone is R/C, and that you haven't got hold of W/T fibre paper. As Sparky says, I would expect fibre paper to have a curl, it normally does for the reason he gives.
    Regards Dave.

    Hi Dave. No it's definitely RC. I bought 2 100 sheet boxes at the same time last week (one normal and one WT). They both look and feel exactly the same apart from the curl on the WT. I am thinking I might be able to flatten the WT by taping up the black bag it is in and putting something heavy on top for a few days, but I don't want to accidentally fog the paper.

    Just a point about the archival washing systems ie: Nova etc.
    I was curious about their efficiency (always trying to find fault with everything me !) so I did a (very unscientific) test whereby I filled one of the washing slots with a dilute solution of coloured water. The washer was then set running so I could observe how long before the water ran clear. It seemed to take quite a long time which indicates that in the initial stages of the wash a FB print is 'stewing' in its own fixer laden water ?
    I think the newer models (Silverprint also make one) now have a complete dumping facility whereby this fixer rich water can be released by lifting an end gate.
    I often use the Paterson RC washing tray to wash FB prints if I only have a few to do. Its quite easy to tilt the tray on end to dump all the water if you need.

    Good point Bill, but the water isn't "fixer laden" the print is. Washing is a misleading term, because fixer is removed by diffusion, or dilution rather than what we think of as washing in the conventional sense.

    Provided the bag doesn't have any holes in it the method you propose may work. I would recommend you double bag for safety. It's a puzzle.

    The very fact that no-one has said he has the same problems with RC WTpaper and I have never seen another thread on this curl problem, suggests that there may be an issue with your batch rather than a characteristic of RCWT and if so, Ilford would probably want to hear about it.

    I'd endorse Dave Miller's suggestion to contact Simon Galley. You might be doing both yourself and Ilford a favour.

    Thanks. In that case I think I will contact SG.

    I have uploaded my first enlarging and toning efforts to the gallery.

    If anyone has a chance to comment or give advice I would be grateful. I am quite pleased with them, but I know they could of course be better.

    Mark, If you transfer your pictures to the Critique Gallery you will get far more comments than you will from your subscribers gallery. "Ruth" looks to be a fine character study by the way.
    Regards Dave.
