That's what I was refering to.

You're right. But I actually got pretty fair results with four-color
black. The conversion and the press profile (hurry for the print shop)
where accurate enough to preserve neutral grays while four-color
assure solid blacks. Yes, I know odds you obtain a color cast are high,
but accurate press profiling and pressmen that really care are also in
this world. On the other hand, it's easy to select the same document
profile and Print Space.
