Fixing and washing RC papergreenspun.com : LUSENET : B&W Photo - Printing & Finishing : One Thread |
I use Ilford RC papers with dektol dev. and kodak fixer. I noticed the information sheet supplied with the paper says fix for only 30 sec. and wash for 2 min. Can this be right? My old habit from my bromide days is to fix for 5 min. and wash for at least 20 min. Will fixing RC for 5 min. require longer rinsing time? I don't want yellow prints 10 years down the road. Thanks.

I generally leave RC prints (usually Luminos Flexicon) in the fixer for closer to 5 minutes, but that's just my old fiber-paper habits. You can probably get by with 2 minutes in the fixer: certainly, you can turn the light on after a mere 20 or 30 seconds if the fixer is reasonably strong.I generally wash RC prints for around 5 minutes too, but realistically, with good water flow, 2 minutes is probably sufficient. But I prefer to err on the side of too much rather than too little... Water and time are cheap compared to having to reprint stuff! (And I've only had a couple of prints out of hundreds show any fixer staining from inadequate washing in the last five years.)

The Ilford instructions for minimum times require that you follow the process exactly. Longer fixing needs longer washing.I generally give about 5 mins in the fixer, and 20-30 in the wash. In 25 years, I have never had a print go bad on me, and some have been framed on the wall for that time.

For RC, anything over a minute or so seems excessive to me. For RC prints, a fix of 30 seconds and a wash of 2-4 minutes (depending on water flow) is sufficient. Remember that with RC you have to keep "wet time" down to a minimum, otherwise the corners and edges start coming apart. I have used this method for almost 20 years without a print going bad.

If you use a paper-strength rapid fixer or plain old ordinary fixer, use a fix time of two minutes for RC paper. Fixing longer will do nothing except eventually bleach out the lightest highlights. If you use a film-strengh rapid fixer w/o hardener (the fixer Ilford refers to) fix 30 seconds to _no longer than_ one minute, and carefully follow the fixer capacity ratings. Wash time is the same, around five minutes in rapidly-flowing water. Using rapid fixer comes from Ilford's archival fixing/washing sequence for fiber papers and although using it won't harm RC papers there's no significant benefit either.

Greg: I concur with Tony Rowlett. As does Ilford and Agfa (at least).Mike
