drymount question

    Has anyone ever used a Seal press to drymount a poster which has been linen-backed?
    I 'm thinking that using heat and pressure will make the weave of the linen show thru the front
    of the paper and give it surface. The customer wants the wave of the paper totally flattened out and I'm wondering
    if there's any alternative. I believe the original movie poster was adhered to the linen with a water-based paste.
    Would 140 degrees for 90 seconds affect that adherence?
    I'm thinking of using a pressure-sensitive foamboard and a roller.

    I don't think that the heat would affect the linen to poster bond at 140°.
    You could use Mount Cor Canvas which can mount at 130°.
    If your seal press is vacuum and heat, you can turn down the vacuum pressure and then use a cooling plate when you take it out of the press.

    That said, our shop has 2 heat vacuum presses and we also have the option of doing cold press roller mounting with no heat.

    We do laminating, plexi and dibond pressure mounting.

    The safest thing would be to cold roll it to adhesive board.
    Hope this works out for your project.;)

    Just remember that waves can turn into wrinkles if pressed into a sticky substrate...

    DCO with acrylic...no adhesive touches the art, but it's pressed flat by pressure of the acrylic over a rigid substrate padded with several layers of polyester batting.

    A long while ago I used to drymount fabrics - mostly silk by pre-mounting drymount film to a board leaving
    the top peel-off paper on. Let it cool a bit and then remove paper and smooth on the fabric. The film is still tacky when cooled so
    you can press down any waves without committing yourself. The trick then is to reduce the pressure and give it
    a quick squeeze, virtually bring it up to pressure and take it straight out. This means it's stuck enough to fix it down
    but doesn't form a permanent bond. You can peel it off with care. Fabric doesn't behave quite like paper in that it
    is not prone to expansion like paper so it should stay put. If it doesn't you can give it another slightly harder/longer
    squeeze or peel the whole thing off and do again.

    Not sure it would work in this application but worth a thought.

    I wouldn't mount on foamcore though. o_O
