Title: Re: Unwrinkled prints
..I have also used a variety of this method for “direct carbon”... Got the idea from the dry mounting method.. Spread a generous amount of 5% gelatine on the backside of the paper – smooth out- and tape down the edges with gaffa tape. Clearing is simply pouring hot water over the image for a minute. The tape  prevents the backside from getting wet / washed out. When finished the gel on the backside can be washed off as it is still soluble.

Originally used sheets of acrylic, but as clearing was with hot water on one side only of the sheet, the acrylic bends, disturbing registration and switched to using glass instead...,

While waiting for the DVD :D this with acrylic...

Don't look at the image please, just the concept :-)

John,

I used to do very similar thing: I also used rough-up plexiglass, but I used non-resoluble glue and paste only the borders. When all is done, I cut the paper off the plexiglass. Your pasting the whole sheet to the plexiglass sound interesting, but won't the paper detach from the plexiglass during development? I assume you are talking about direct carbon printing.

A 5% gelatine solution brushed over the  entire back of your print paper to stick it to a sheet of plexiglass (  perspex) will keep it flat. Allow to dry thoroughly.

First, rough up the surface of the plexi sheet  with medium sandpaper so the gel will adhere. Lay the print sheet face down on  another larger sheet of cheap paper when brushing on the gel. Then, position  the plexi sheet on the gel coated paper and press down with the palm of the  hand smoothing out the contact from the centre of the sheet out towards  the edges. Finally, turn the  pack over and continue to smooth out the  contact and flatten air bubbles. Remove the cheap paper and clean up the edges  with tissue. If you are coating with gel emulsions the sheet will snap off  of from the plexi sheet after the process is done.

               Hope this helps.

               A DVD of this activity, for those with limited visual  imagination, may be available in 2009 at a cost of $45 plus postage and  packing. ( Dont freak out. Its a joke )

But, seriously, this has worked with  very thin papers, 40 gsm.

Hope it works for you.
