Hello Cor,

Make a light contact positive from your negative on a piece of lith
film and sandwich it on top of your MACO negative and you should be
able to achieve just what you wanted.

You can develop the lith film in standard print developer. The
resulting positive should be dark only at the deep shadow areas where
you do not want gum to cover.

I agree with Loris that digital is the way to go, especially with IR
images where density ranges cannot be as easily controlled.

Good luck,
