re: using blue gel to change response

I've done this with chromogenic BW film. The results were a bit more subtle than true blue-only. I used a full CTB gel which has some green/yellow in the...

The only experience I have with laser prints is when making circuit boards. There used to be a spray on light sensitive resist, can't find it any more. I now use silk screen light sensitive mask....
