Another dry mounting question

Create a Post
If it is really dust free, then probably from the release board/release paper/platen ... try using Kooltack with a Permalon release board ... smooth!
 
There is still dust around your dry press to cause those dents.

I will on a regular basis take a cloth and Naptha or similar solvent to wash the release boards. I also use a drafting brush to clean both the foam board and the back of the art. Yes there can be dust on the back of the art.
 
I truely don't believe it is dust. I had dry mounted two other posters that were just a tiny bit thicker and they had no real divets. I think the differents has to be the foam board.
I have ordered some regular foamcore,(we don't keep it in stock) and I have ordered some new product called "Cool Tack".
Have any of you used this product?
 
What do you mean by dents? If it's a pimple, there's something under there, if it's a pin point divot, something was on top. If it looks like the foam just collapsed under a small area the size of a quarter or there's a faint crease line all the way across, something is going on there.

I had two or three drymounts in a row come out with dents and it stopped when I changed the release board. Those boards are great. I go through 30 a year or so. The old board had no visible flaw that could have caused the dents, but it was old and under 200lbs of pressure, things you can't see really skrew up your day.
 
Why do you use acid free foam board when drymounting?
 
Silicone release boards are not perfectly smooth and can cause orange peel - Permalon release boards are the smoothest ever - and provide excellent results - highly recommended.

Search for 'Kooltack' on this site and you will find many discussions about the virtues of this product.

BTW, Kooltack is more than just one product. See this link for more info: http://www.kooltack.com/OURPRODUCTS.html
 
I personally have better luck controlling orange peel with Artcare than with regular clay-coat foam in our press.

You mentioned you use Hart foamcore because it's less expensive. Here's a hypothesis: is the density consistent throughout? Is the core more porous in places, and denser in others? I'm not certain it could be a factor (I'm throwing this question out to framers more experienced than I) but is it a possibility that could cause these dents?
