    Mounting Cyanotypes

    I've done a bit of research on this and as long as I use an acid free mount board I can't seem to find a valid reason not to use my dry mount press.
    Any opinions welcome.

    The collectors say it ruins the price of the photo. I rarely see any E Weston photos that aren't dry matted and trimmed to the edge of the image.

    Not just any acid free board will do: It must be an acid free and unbuffered board (actually a little acid is ok). Same with the dry mounting tissue: Neutral PH or even slightly acid PH.

    I've read that cyanotypes can fade over time but can be rejuvenated in a peroxide dip so permanently mounting them is probably not a good idea. Also, unlike regular prints, buffered will cause fading.

    Actually, just putting them in the dark for awhile is suppose to rejuvenate them, too.

    I would go with unbuffered rag board.

    Pete, I find that with my platinum/palladium prints (on heavy watercolor paper), that dry mounting is not needed to keep the prints flat. I just top hinge them behind the window.

    You might wish to make a quick test with a reject print -- tear it in half and put half in the mount press for your normal time and temperature -- then compare it to the other half...just to see if there is any change due to temperature.

    Re: Mounting Cyanotypes

    Century has the right matt for Cyanotype here in the states but you will probably have to have it ordered from the distributor as most art supply houses stock the buffered matt board. I think it's called Museum Matt or something like thant. Color selection is limited to 3 or 4 colors but one is white.

    Calcium Carbonate is normally used to buffer media acid free. However the Cyanotype disintegrates in an alkaline environment so you need a neutral PH paper, mounting board and adhesive if you dry mount. B&H here in the US sells a neutral PH dry mounting adhesive.

    Finally, and from what I've read on it, Vaughn is correct in that if you see your Cyanotype begin to fade from display, just put it in a dark place for a little while and it pops right back.

    Ain't they fun! I'm going to print one this week when the sun reappears.

    Re: Mounting Cyanotypes

    Thanks again. I have neutral hot mounting tissue (I've had it for a few years but never checked if it was neutral until yesterday). I can get Peterboro museum mountboard, not cheap. Some boards claim to have a neutral pH facing paper would this and the neutral mounting tissue protect the print from alkali damage? I can also obtain foam centre board with either acid free or 100% cotton rag face papers, would this be OK in my hot mounting press?
    Thanks for your patience,
    Pete.
