Wayne: Wish I could provide you with hard numbers on energy usage but I'm afraid
we never took the step to actually measure this energy consumption. As to
platemeking chemistries, it is again a case of "it depends". We have just
discontinued use of yet another solvent-based plate processor for traditional
lithographic plates (even though we had recycled the used processing chemicals
back to the manaufacturer). We are attempting to utilize only the most benign
chemistry-plate systems we can find.

I am not aware of a specific comparative studies. Such a comparative study might
be very interesting to review if one were found to exist.
