Default Washing

I did a wee search and couldn't find much on print washing.

So, for those of you with homemade darkrooms, how do you all wash your prints?

I'm on a small budget at the moment, so i use a tray slightly larger than the paper under a running tap in the bath tilted slightly so the water runs out the not tap side.

Sounds good to me Joe. If it's RC then the tap can run quite slowly and still change the water adequately and if the water is coming out about or above a min of 5 degrees C then 2-3 minutes should be long enough.

I should qualify this answer: I am quoting Ilford instructions on temperature although 5C does seem low. I haven't had to use water at this low a temp as I am able to feed in some water from the hot-tap as well but if Ilford say 5C is enough then I'd trust its judgement.

If you have to rely entirely on cold water have you checked what the cold water temp is in December in Glasgow? It may get close to or below 5C. Worth checking

Hi. If I am doing RC, I either use a Paterson high speed washer, or simply hold the print under the tap. The Paterson washer is just like a tray with hoses attached. I add Hose-Lock fittings to get these, and film washers , on and off the tap easily. There are two sizes available, 8x10 and 12x16. I use the smaller one, but both can be found quite cheaply second hand. The cheapest way is to hold each sheet under a running tap. You can do so in such a way as to get water running over the whole surface. Turn it over from time to time, and 2 mins total should be plenty. You can adjust the temp to suit, and your hands tell you if its getting too hot, or cold. Fibre based papers need more careful and prolonged washing, best done in a proper washing tank.

I saw a good idea on a Youtube video, take a plastic container slightly bigger than your prints and drill holes in the base of 1 side to allow water to escape and allow a flow of water over the print then simply run the tap into the top of the box for the next 2mins or so. Beats paying 70 for a commercial version of the same thing.

RC paper is much easier to wash, five minutes under running water should be fine. To be on the safe side add a two minutes in hypo-clearing solution and should be super clean. I lay down the print emulsion up on a tray laid upside down at the bottom of the sink and let flow the water from the tap.
Fiber paper is a bit longer process but quite similar, for me. A brief rinse under the tap , five minutes in HCA, 15 minutes set up as for RC. I cannot assure beyond any doubt this is enough, let alone call it archival, but so far no problem. For sure shorter times aren't enough, as after a while brown stains start to appear...
Having said all that I agree a proper washer would be ideal, more time to print new pictures or taking new ones , way less thinking back about archival matters. Money permitting...

Cheers, M.

I have a large print washer installed in the house, although my wife insists on referring to it as 'the shower'.

What you do not want is for some of the fixer-laden water to stay in the washer. If you put water in one end of a tipped-tray and let the water come out of the top of the washer on the other end, this might happen. Ideally the "bad" water should come out of the bottom of the washer. The idea of drilling some small holes in the bottom of the washer sounds like a good one to me.

I keep RC wash times down to the minimum. I find the extra washing from toning can cause 'cockling' at the edges, and the surface can take on a bloom. Ilford suggest 2 mins in running water and I stick to that.

Read the Ilford RC Paper fact sheet - http://www.ilfordphoto.com/Webfiles/20114271389417.pdf

120s in water temps of 5C or greater with running water

Ilford produce some very reliable help on their web site - http://www.ilfordphoto.com/home.asp

Their advice is the result of extensive testing and analysis of the data it produced.

Advice on internet forums is based on personal experience, urban myth and bull s..t

Put your creative energies in to producing stunning photographs and prints rather than trying to prove Ilford/Kodak/Fuji/Adox/..... wrong
