I use a Bogen Technal 560, and the heat could be more even. When I measure it at different points, under a distributing sheet of board to make it more even, it varies up to 9 C at extremes, and it floats some 8 C between cycles. All this means a lot of testing of adhesion, and having to return prints to the press once or twice if they pop, but I do bend them rather severely after mounting. Such strong adhesion helps them cope with very humid display conditions, which I once had to learn to deal with.

I hear that HotPress is one to look out for if you have the funds and a ton of space.
