Default Print washers

I'm looking into making my own multi slot paper washer.
My question is to all who use this style of paper washer no matter who the maker is. I would like to know what the distance between the slots are. I have a single sheet washer from nova that has a 12mm gap are the multi slot ones the same.

Mitch,

I have 2 washers: one for 50x60cm and one for 40x50cm and both have gaps about 12 mm.

Hope this helps!

Hi there,

the width of the slots is not critical. Far more important is the flow of the water, that all of the print gets washed, that you can 'dump' the water easily during the washing sequence, etc. Achieving this is not that easy. You also need to choose your construction materials with care due to the high pressure created by so much water.

Whatever you choose to do, there is no better way to proceed than first reading Martin Read of Silverprint's exhaustive investigation of the washing process:

http://www.film-and-darkroom-user.or...=washer+martin

Personally, unless you particularly like undertaking DIY projects and, having read Martin's article, are willing to go through several versions, I would not bother making one but rather buy a Silverprint Archival Washer.

I have had mine for many years and a completely satisfied with an expensive but thoroughly worthwhile investment. I just put it on, check the flow rate and leave the washer to do it's job.

Best,

David

I have a Summitek slot washer (no longer made) in which the dividers are 3mm thick and at 16mm spacing, so there's 13mm space in the slots.

The dividers are textured on both sides making it easier to insert large prints.

I have now read Martins article. Basicly when it come to washing your prints less in more. narrower slots with textured sides are more effective than large ones but they need to be a certain size so the paper does not stick to the sides and allows easy access.

I think I will still build my own washers but not what I had orginal thought of. this because Martins article has show me that what I do at present meet a good standard I just need to be able to wash more prints at once.

Thank you to everyone who posted.
