gEDA-user: filmless photolith PCBs

[John Griessen <john_g@xxxxxxxxxx>]

A while ago, I got involved in doing some film copying of old pcb artwork, and 
the film that is readily available is not very high contrast, and high contrast 
developers have some toxicity, so I was thinking, " how do you expose a 
photosensitive copper laminate resist without film?"   There is a type of 
imagesetter/photoplotter machine that drugstores and other photoprocessors have 
been using, and some are already obsoleted and available for $40 to $120. 
They're called digital film recorders by that industry.

Has anyone tried anything like this, either an industrial machine, or a consumer 
film printer for exposing photoresist directly with no film?
