anything like Onyx Postershop. It's (v6.5) Total ink Limit tables are

What did you say is your current RIP?
Hi Roger,
It's Scamvec's Photoprint 4.6. The printer is a large solvent inkjet
with 6 colors CcMmYK. I'm defining the ink limits in RIP and using PM
5.0 to build the profile. To get rid of the peppering, I will try PM
5.0 "black width" but as I observed that using 75% K I would not "mess"
with the deep shadows, I wondered if I could also reduce the maxK, but
I'm afraid in loosing some saturation in dark colors, in particular dark
yellow (a.k.a brown tones).
Of course I can try all different options (black start, maximum black,
black width, GCR), but reading so many patches with an eye-one pro is
very time consumption!
Best regards,
Lorenzo
