De-bossing mat board for small prints
I want to de-boss a mat board for dry mounting prints about 5x7 inches. I know this is usually done with an etching press, but I don't have the room. I'd like to know if it is possible with a small book press? How exactly is this done?
Thanks for the help.

Re: De-bossing mat board for small prints
A back of the envelope calculation says a small book press, well greased, should be able to put down 8,000 lbs of force without much problem. Over 40 square inches that would be a pressure of 200 psi. To see the effect of 200psi, try putting a 1 square inch block on the mat board and then standing on the block (do it on paving stone or concrete so there isn't any deformation.)
You should, of course, use a Woodburytype press...

Eric,
A book press works well. Jan Pietrzak (sp?)has used one for years.

A used Carver press with 20 ton capacity will work well. Check ebay. You'll need a flat head piece for the press though - probably surface ground in a machine shop.

Jim,
Close but not correct. You got the name right, but not the press. I have a small etching press (14x28in bed) that does the job just fine. Nicholas is on, as far as the pressure is concerned. I once asked a press builder what is the pressure at the point the rollers touch the felts, paper and bed of the press. About 2,000 to 4,000 lb/in.
So you would need a BIG book press to do that.
Eric come to Santa Fe and we can talk about it.

Sorry to be so ignorant........but what the heck is De-Bossing?

de-bossing is the opposite, with respect to the top surface, of embossing. Deboss is pushing the finished surface down and embossing is pushing it up. A debossed mat is one with a well that created by compressing the mat board. The pic is mounted in the bottom of the well and when put behind glass, doesn't touch. It has the look of an overmat without the overmat. It is a very nice effect and typically done with an etching press, which is a roller press.

Yeah, what Kirk asked.

Kirk,
De-bossing is an impression into paper, embossed is a raised design or logo in/on paper. Kirk, remember the recessed area my prints sit/set in on the water color paper, that is a de-bossment into the paper.

Jan, I'd love to come out to St Fe.
I don't have room for an etching press or a Carver. Kevin Martini-Fuller says he knows a way. Probably involves a car jack.
I emailed you. Hope the old address works.
