Re: Attn. Tor + All re drying w/c paper flat.



Hi John!

Tanks for the suggestion. Currently I do gum prints, but plan to do some attempts on van-dyke-brown prints as soon as I get my ordered chemicals and have different papers from about 200g to 600g. The new rough edge paper is around 400g. As both processes require a thorough rinse of the paper, I don't think it's feasible to have it on the glass plate during the entire process, but it might work to coat the back of the wet paper after the last rinse and then snap it onto the glass to dry. I'll pick up some sandpaper after work and give it a try tonight and tell tomorrow if it worked or not :)

Requiring weights to keep the paper down does not sound like a good idea to me. First of all, at least the gum print surface is very delicate and easily damaged and I would expect weights, at least on heavier papers, to leave marks?

Hi Tor, You have not specified the processes you use or the weights of the papers but, hopefully, this will not make any difference.

If you coat the back of the w/c paper with a 5% solution of gelatine and stick it to a sheet of lightly sandpaper roughened 2mm plexiglass, allowing the paper to dry thoroughly, ''before'' carrying out the process, you will be able to snap the paper off after the process when it has dried, and it will be perfectly flat.

Or, allow the paper to dry, after the process, with the ripples and then do as above coating the back of the print with gelatine solution and holding it flat on the plexiglass with a heavy weight to keep it down.

I have used this method on papers from 80 gsm to 400 gsm in a variety of textures with no problems.

Hope this helps and good luck.

Subject: Drying of handmade watercolour paper


Hi!

To dry watercolour paper used for different fine print processes, I usually use adhesive tape to glue the paper onto a glass surface to keep the paper flat and prevent it from rippling during the drying process. This of course means, that I have to cut off the edges where the tape is still stuck to the paper after it is dried. Now I've got hand on some really nice hand made paper with "rough" edges, which I'd really like to keep, but if I dry the paper the described way, I would have to cut off the edges.

Do someone have a suggestion how to dry these papers and make sure the paper stays flat without ruining the edges with the tape?

Regards,
Tor
