    Default Does Spraymount Ruin Positive?

    Going to try exposing screen at home.

    I am currently having professional positives run from an image setter -Does spraymounting down the positive make it permanently sticky or make the ink lift off?

    If it stays sticky, is there a way to clean the glue off without damaging the positive?

    TY!

    i spray mine with repositional adhesive. I never had the need to remove the adhesive from the positive afterward. I spray it lightly.

    DON'T SPRAY MOUNT YOUR FILMS!

    the best case scenario is that you'll have an extra one million pin holes you'll need to fill before printing.

    that's my experience anyway - just expose with screen on a flat surface - with light source either above or below, depending on what you can rig up.

    use a piece of foam and glass, you don't need spraymount.

    But...you can usually clean spraymount with turpentine or paint thinnner (not laquer thinner ot 'hot' thinners) from imagesetter or photographic positives.

    test it first.

    a little trick if you are using these films or rubylith - do the image in reverse so emulsion is on the back of the film, then not a problem cleaning and damaging the image or the ruby.

    if it is waterbased spray, it will come off with water, the film won't be affected either.

    I used a little double stick tape to hold the pos in place and then sandwich the pos between the screen and a piece of glass and weight it with books to make a good seal. But my light is on the bottom, not above.
    What is to give light must endure burning.

    i came in to recommend just that! i got to learn that the hard way of course, but giving it a light spray has been doing wonders for me. when i just used glass, it was just never that tight on the screen..

    I do it all the time, when I'm shooting a screen with the sun on an oversized screen that will not fit in my exposre unit. I just spray them lightly
