    I am planning on having a series of prints from my Epson 1280 that were
    printed on Epson paper using Epson inks dry mounted. Since the press uses
    temperatures up to 350 degrees I was wondering if the inks can handle that
    heat. The frame shop that does my dry mounting was unsure of an answer.
    Has anyone done this? Thanks.

    The inks might handle the temprature but the plastic coating on the paper
    won't!

  3. I've had quite a few "computer-generated" prints mounted in this way
    with no problem. I do my own mounting and framing now, however, and I
    use a 3M product called "Positionable Mounting Adhesive." It's pretty
    easy to use, and doesn't require any special equipment.

    It's easy enough to produce another copy of the photo, so I'd let them
    give it a try and see what happens. If it ruins the photo, you can use
    PMA or something similar.

    In my pro days I did a lot of dry mounting, and never went anywhere near 350
    degrees. That is an absurd temperature for dry-mounting. All modern
    dry-mount tissue is designed to work with PE (plastic-coated) papers, at about
    180- 190 deg. F., as also is texturizing film.

    Choose or make a test print and get the shop to mount it with Seal (tm) or
    similar tissue at 185 deg. and check the result.

    Why bother with heat anyway?
    I've been using a vacuum mounting press with EVA adheasive sprayed on the
    board for most of this year and never had a failure. When I used a heat
    press I got failures and high costs. Should be a heap of framers using
    vacuum. None around my way use heat presses.

    From a pro point of view, heat mounting produces a high-quality, flat and smooth
    mounted print. Cold adhesives are prone to producing a less-flat result,
    variations in glue thickness showing up as slight undulations in the print
    surface. A vacuum press with a flat metal platen might do a bit better, but in
    my experience, dry-mounting looks the best.

  8. Though dry mounting as an archival method is the subject of much debate,
    I am aware of *no* reputable source that advocates vacuum mounting with
    any spray adhesive as archival. It is difficult to find spray adhesives
    that are even neutral-pH, much less conformant to the much wider range
    of requirements for archival use.

    My concern with dry mounting inkjet prints -- whether pigment or dye --
    would be the effect of the press heat on the permanence of the inks
    many years down the road. This is difficult to test for and I am
    unaware of any published information on the effect of short-term
    exposure to high heat on the stability of the dyes or pigments of any
    mainstream ink system.

    Consequently, I would recommend the 3M PMA for this purpose, unless
    mounting prints for personal use only with full understanding that
    either spray glue or dry mounting might result in a significant
    decrease in permanence.

  9. I certainly can: all you need is a multi-stage reaction, where the heat
    of the mounting press supplies sufficient activation energy to kick
    off one of the early stages (which need not actually itself produce
    significant color change). Alternately, it's simple enough to think
    of a reaction in which some component of the paper's coating breaks down
    immediately (suppose, for instance, you end up with something with lots
    of free electrons) then degrades the dye or pigment over time.

    I too have dry mounted conventional photographs for many years. But
    the chemistry of those processes is well understood compared to the
    chemistry of the many different dyes and pigments used in today's
    inkjet printing, much less the diverse constituients of the paper
    itself. More important, there are decades of experience with dry
    mounting and silver-based photographic processes. As far as I can
    tell, dry mounting inkjet prints is still a big question mark.
