Hello,
in your case, you may play with the available settings for the media type
(matte, glossy, etc.) and quality (standard, high, ultra-high, etc.). This
will make the printer use the internal separation presets. Choose one that
provides you acceptable neutrality and quality based on your grayscale
images.
Once you found a suitable combination of settings, create a profile based
on those. Make sure you set the exact same settings at printing time again
when you print images converted to this profile.
Hope this helps.
Best regards

Thank you Daniel!
The printer is a standard RGB inkjet printer (Canon PRO-4000). I cannot
think of any method knowing the GCR other that the printer utility that
reports the ink consumption of the 12 inks for every print. I will have to
print a grayscale with various media types and check the ink consumption.
The less the colors are used the more appropriate the media type will be.
Correct?
Thanks again.

Hello,
this is more a question of methodology than of profiling.
Metamerism is true for every print and may be minimized by physical
parameters only. The profiler will compose colors true for a certain
illumination spectrum. If the illumination changes, the color appearance of
your print will change accordingly.
You said BW prints are in your focus.
You can influence the metamerism stability in printing only by the GCR
(Gray Component Replacement) in the neutral colors. The more black is used
to reproduce the gray axis, the lower the perceptual illumination impact.
Are you using a RGB or CMYK controllable device?
- On a CMYK device, you may adjust the K-generation curve for your
profile in order to use a minimum of CMY along the gray-axis. Depending on
your quality expectations. You may also adjust the GCR in your image data
prior to printing without fiddling too much with the profiling options.
- On a RGB-(driver) device, you may select a media/speed-preset that uses
a suitable GCR prior to profiling.
Convert your images with the relative or perceptual intent to avoid
forcing CMY into the grays.
Be aware, too less K along the gray-axis may reduce the image-dynamic to
an unsatisfiable result.
So remains a compromise between print quality and metamerism stability
for your particular application.
Mit freundlichen Grüssen

Hi!
I want to make with i1pro2 a printer profile for a paper full of OBAs.
The paper is Hahnemuhle Baryta FB 350. It has a strong magenta cast. Most
of the prints will be BW and are going to be seen under various lighting
conditions. What Argyll options should I use for building the profile?
Thanks in advance for any input.
Panagiotis
