RE: Wrinkled Prints



I print on velum with cyanotype and have the same wrinkling issue.  Even if you humidify the room, when the print gets to a lower humidity area, the wrinkles will get worse.  I use a hot iron (better than a press since you can sweep the iron to remove the wrinkes rather than press them in more) to get out most of the wrinkles and then mount in such a way that paper movement after mounting will not cause more wrinkles.  Not ideal, but it is working.

I've dry mounted print made with liquid light before using the Seal Colormount so you should be able to heat the press and flatten them. If you're worried, just try it out on a test print first.

Hello,
 
I am applying silver emulsion (liquid light) to Japanese paper.  I have posted in the past about myriad problems and have appreciated all the helpful suggestions.
 
My latest problem is that the prints dry (after typical darkroom processing) with many wrinkles.  A few wrinkles are lovely, and contribute to the three dimensional look I am seeking, but when the piece of (otherwise beautiul) paper is completely crinkled, it is both unattractive and makes the image hard to read.
 
I have had this problem much more frequently lately, so I'm guessing it is related to the increased forced hot air heating (and low humidity) now that we're having a deep freeze on the East Coast.
 
Here's what I've tried so far:  after squeegee-ing the prints, I lay them on screens and surround the edges with little stones to keep the whole print from curling up.  After they dry a little bit, I put  pellon around the prints, and then weight them down with a few books.  They never completely dry in the pellon, but when they are only a little damp, I move them to blotters for the final drying.  The result is better than if I left the prints on the screens for the entire time, but still pretty lousy.
 
I do have a dry mount press, but I'm guessing the heat would destroy the emulsion, and when I use the press cold, all it does is flatten the creases, not restore the paper to a smoother state.
 
I do have a humidifier that operates with my home heating system, though I'm not sure it generates much moisture.  Would a free standing humidifier in the darkroom be a good idea?
 
I'd be grateful for any advice.
