Aaaand, replying to myself. If that's what I suspect (the printer/RIP
producing pure K plate from the achromatic values), maybe there is a
way to prevent it:
Try to add some color. Instead of pure black, use RGB 1,1,5.
Sometime RIPs, Printer drivers and preflight softwares have specific
rules, as converting pure black to K-only black.
By making it very dark gray and adding some tint to it, you cheat the
RIP so it doesn't do that.
That should work giving you a nice, deep black. Try it and let us know
how it went.
