Homebrew PCBs

I was wondering if anyone can give me some advice, looking at the 
threads recently it looks like lots of people here have tried 
sensitized boards.

This material appears to be the same stuff as silkscreen printers use 
on silkscreens, where the exposed areas to intense light are hardened 
and the unexposed areas are washed away with water.

Do any of the sensitized boards or materials react to INFRA-RED light?  
I have an infra-red laser diode on a cnc machine, its not powerful 
enough to cut stuff with but will smolder black foams.  I was wondering 
if its possible to use that to rastorize the image, but I dont know 
about all the different types of sensitizer or what types of lights 
they react to.  I know in screen printing, they make types which react 
to a 4k watt metal halide bulb, and newbie stuff that works with a 150 
watt lightbulb.
