To further illuminate the question, these are the recommended values 
whan using Photoshop:
Engine: Adobe (ACE)
Intent: Relative Colorimetric
Use Black Point Compensation: Yes
Use Dither: Yes
    Ink Colors: SWOP (Newsprint)
    Dot Gain: 25%
    Separation Type: GCR
    Black Generation: Medium
    Black Ink Limit: 100%
    Total Ink Limit: 240%
    UCA Amount: 0%
for the custom CMYK settings.

Perhaps there is an ICC profile that can take care of all this.
