Profilemaker settings

Can anyone answer a couple of questions regarding making profiles in
PM please? I principally use it for making media profiles for our
Inkjet devices and am a bit in the dark as to the optimum way to go
about generating them.

  1. Perceptual Rendering Intent - Paper-colored gray or Neutral Gray?
    Does this depend on colour of the media?
  2. Gamut Mapping - What the best one to use generally and why?
  3. Separation - I generally use GCR3 (pre-defined Inkjet400) as I’ve
    made my total ink settings already on the RIPs. Right or Wrong?

Kind Regards,

In my experience, Alex, I’ve found the following settings to be most useful:

Rendering Intent: Neutral Grey (use Paper-colored Grey if profiling a media with a noticible color bias to it)

Gamut Mapping: LOGO Colorful (this is the improved color mapping algorithm developed by the Gretag-MacBeth ProfileMaker team several years ago - I participated in the beta-testing program for that enhancement.)

Separation: GCR3 (most often recommended for inkjet printing)

TIP: Before generating your output profile, use the “Neutralize” button within Define Black Point to automatically limit and adjust the CMY curves for a more accurate neutral-gray axis.
