The PDF's are Adobe RGB based also. All files are based on Adobe RGB.
The displayed reds and browns look significantly warmer than the prints.
The printed reds and browns measure within Delta 3 of their digital values.

HI Group,I'd like to see if anyone can help me get any further with monitor accuracy without spending a fortune on hardware...
I profile monitors for architects who display renderings that are usually colored in Creative Suite (Photoshop & Illustrator). The files are converted or created in Adobe RGB. If the files are created in non-Creative Suite apps (Autodesk apps) then they assign sRGB and convert to Adobe RGB. Most are PC's with Dell monitors.
The office printer has a Fiery Rip and I have it profiled so the color accuracy is mainly under a Delta E of 3 for most colors. Files are printed from Creative Suite with "Let Printer Determine Color" to the Fiery which prints through the custom made and fine tuned/edited profile.
Monitors are profiled with a Spyder Pro 3 (Gamma 2.4, White Point Native) and the brightness and contrast of the monitor hardware are fine tuned by putting a color managed print next to the monitor displaying that file before and after the monitor is profiled. (This accounts for office lighting and human eye) The printer profile or some other profile that makes the display look good is set up in Adobe's Proof Setup menu (Relative Colorimetric rendering no boxes checked) to get the displayed file to keep the saturation of colors close to what the printer makes.
The problem...Number One, file colors display slightly different as PDF's versus native files in Creative Suite.Number Two, certain file colors such as reds and browns display less warmer (more neutral) than they print.
In case number two, I have printed those files on expensive color managed plotters to verify the output of the Fiery/office printer and they looked alike. So I am sure that the printer output is correct and the monitor is to blame.
Both cases, yes the office lighting is not perfect. Grays print slightly pink and I put a plus green correction in to compensate for that. The main colors (CMYRGB near the edge of the gamut) still fall into the Delta E of 3 or less. I do take the prints outside to see what they look like under daylight and the office lighting is not radically different. The reds and browns in the prints are significantly warmer than what we see on the monitor.
The only adjustment I think I can make at this point is to edit the profile loaded into the Proof Setup menu to coerce the monitor to warm up the displayed reds and browns to match the color managed prints.
My eye is very experienced and my clients are seeing the same thing.
Any ideas my color cohorts?

Hi,
If I am reading your post correctly, the PDF and AICS2 files display differently but print the same?
My first thought is what settings are you using to create the pdf files?
