Making a contact print between an inverted grayscale image on an LCD screen and a sheet of resin coated photographic paper should seem like a simple task but I've been having trouble with getting mine sharp.

Has anyone tried this with good results? If so I'd like a detailed description of your exposure process.

I am using a MacBook pro because I like the glass surface and it's what I have. I prepare a full screen slide show of a black image my negative grayscale image and another black image and put it to sleep on the first slide. Then I tape a test strip or sheet in place wake the machine and use the arrow keys to time the exposure without lingering at the end. I then remove the paper. I can slow down my timing by doubling up a #1 filter. However the result looks pretty blurry. I attribute this to the glass thickness but haven't had the oportunity to try a monitor with a plastic film like my samsung dvi monitor (the MacBook has a proprietary display port and my pc broke months ago).

Sounds like you're right about the thickness of the screen glass. The blur radius would be the distance from the actual pixel behind the glass to the paper's surface, which is probably quite a bit longer than the size of a single pixel, which is what you'd want. And even if it were only one pixel's width in distance, you would still not be able to see the sharp square edges of pixels, or the black lines that separate them from one another.
