I guess this is the only place in the world left where I can find an answer to this.

I print lots of editorial work for magazines and would like to publish more b&w.; My editors are always grunting at the idea because results are usually less than satifactory, looks muddy and with tonal compression. The smoothness and subtle grace of carefully manufactured B&W; is simply lost. Now I am studying a lot on this (thanks for the great books Bruce, read them all) and started experimenting with quadtones. Since magazines print in CMYK and I cannot ask for special inks I converted my images to CMYK quadtones using the Stephen Johnson's presets. The images looked great in my calibrated monitor. So I sent the files to the prepress bureau to be turned into PDFs to print directly to plates. Here is where the problems started. They were unable to process the quads. They simply couldn't recognize a grayscale file with the curves attached to it. They are working on a Scitex system and I recall Bruce Fraser mentions some kind of trouble with duotones and Scitex systems. We were able to make films out of the quads. These were then scanned (oh my god!) and turned into PDFs and of course the results were VERY muddy.
I pulled a million hairs off, screamed and kicked and finally was told that I was going to be given a free ride in the press where I could put a test and see if we were able to print a quadtone photograph.
You don't get this kind of opportunities everyday so I want to make the most out of my test.

1) First I would like to receive advice on what could the bureau be doing wrong that they haven't been able to produce PDFs out of the quads and

2) second some suggestiones on how to make my test so I can make the most out of it.
I have some access to the guts of the bureau since I have very good relations with them and could be permitted to tweak some settings in their hardware and software with their techs.

3) Could I do the same with a regular press as I do with my Epson 2200? : I convert the b&w; to special pantone ink quadtones and print in the CcMmYK inks and it looks great. What would happen if I did that with a regular CMYK press? Can you fool the system?

I know there are a lot of questions in this thread, but please bare me and thanks a lot in advance.

Sergio
