Nuarc and print contrast question

Sandy:

First I'd like to thank everyone here for the wealth of information made available by this list.

I have a question for for the group; I'm looking at a Nuarc plate burner and it seems it might be just the ticket, it incorporates a vacuum frame, intergrator and a light source. Other posts of yours seem to indicate that you may own one. I do have a few questions regarding its use: what do these things weigh? How big are they? In what manner does the intergrator work, does it measure in candle feet? Can I use this with the power supplied by a wall socket in my home (USA)? What kind of light source are they built around? I'm sorry for the machine gun blast of questions.

One final question though, so far from what I've read, amount and opacity of pigment , senitiser strength, gelatine thickness, light intensity and negative contrast and density all effect the final print contrast. Can anyone point me in the direction of a paper or study that systematicly explains these issues as it relates to carbon printing that can provide repeatability?

Thanks
