    AFAIK, all commercial emulsions are normal contrast for printing paper use.

    You may have to make your own. A simple AgBr/I emulsion is probably sensitive enough at that wavelength, but there are dyes that will sensitize this better. There is a web site for making laser emulsions.

    I have been unable to post for hours, and now things are coming out in the wrong order. Someone is playing with the time stamps on entries.

    Very high contrast green/blue emulsion for coating glass plates?

    I would like to find a very high (graphic arts) contrast emulsion
    which I can coat onto glass plates. Plates are approximately
    18" square. I'll be exposing to 488nm (blue-green) light from a
    laser. I want to try to achieve Dmax of 4.0 or better.

    Any help appreciated.
