This is what I do and it works just fine. I've never had paper "burst" on me, but I do use double weight paper.Alternative method to get FB paper dry and flat without dry mount press
This method I learned about 20 years ago from my photography teacher J.Janus...If you dont need the high gloss, then a way of getting FB paper photos dry and absolutely flat without a press is sticking them on a glass pane: You put the still wet sheet of FB paper on the glass pane, so that you can see the picture. Then you carefully clean the surface from water drops, a little bit but not too much with a soft sponge.
All the the edges of your photo you fasten with a special adhesive tape on the pane. The tape is made of paper and is for instance used to fasten water colour papers on a board. Therefore this tape should be available in shops for artistry equipment. This tape is not self-adhesive. You have to wetting it a bit with water (use the sponge again) on the adhesive side. The tape should stick with it´s one half on the photo´s edges and with the other half on the glass pane. It has to overlap in the corners of the photo so that the photo is completely surrounded by the tape.
If this is done you have to wait a few hours until the photo is totally dry. Then you can carefully cut it along the edges from the glass pane with a cutter. When using this drying method you have to make the picture a litltle bit smaller than the FB paper. It is because a part of the adhesive tape stays unremovable sticking on the border of your photo paper and you have to cut it away in the final step.
I used this method many times primary for large formats about 16 x 20 inch and larger (for the smaller sizes drying with a mounting press is easier and faster) and it works very well. In the drying process the paper shrinks and therefore becomes flat out of itself. With the single weight papers it can happen that they burst during the drying, so check it before starting with this method and a lot of photos of the thin paper type. The double weight or thicker FB paper never made any problems.
Anyone who understood? Further questions?
