color magement in Painter IX
Bernd Ertl
Hi all,
I am bit stupid when it comes to color mangement:
I got my screen calibrated to 6500K and 1.8.
So far the results look promising in Photoshop.
Just what do I do in Painter? Which arrows need to be clicked etc.?
I work mostly for advertising agencies, sometimes print illos, mostly
storyboards.
Any help appreciated.
Bernd

Hi Berndt,
Maybe I can help you even if I'm new to Painter. I have used Corel apps for
a while and have a reasonable understanding of how the Color Management
module (wich is the same in Corel Draw) works.
Why do you want to use CM in the first place? Well it's because if you want
to output to any other media than the monitor screen, i.e. printed media,
you want to know what the stuff will look like when printed. As you probably
know, colors on screen and on paper are very different animals. Colors on
screen are additive, made of light and are defined in the RGB color model.
Colors on printed matter are subtractive, made of reflected light and are
measured in CMYK color model. Now, CMYK color space is smaller than RGB
color model, but when you paint on screen you use the RGB color model by
nature. The colors that are out of the CMYK range, out of gamut so to speak,
will be forced to fit into the CMYK color space when printed. So, if you are
planning on printing your artwork you probably want to know what it's going
to look like already when painting it on screen. That's when CM comes in
handy. What it does is that it gives you an impression on screen of what the
printed painting will look like.
You go to the CM module and select one of the presets. If you want to be
more accurate you can load your own monitor profile (that you can produce
using Adobe Gamma in Photoshop, or use a hardware device like the Spyder for
higher accuracy) and maybe a profile for your printer, usually the generic
profiles work fine though.
Hope this helps a bit,
Lars

Hi Lars,
thanks for your reply.
I am still not sure which arrows to activate in the CM window in Painter.
Since I won't print my illos myself I can't see the point of using a printer
profile of my printer (correct me if I'm wrong).
And do I use f.e. ECI RGB for the central RGB and the screen profile
obviously for the monitor setting?
It is rarely the case that I get a CMYK profile of the printshop, but I
guess that would go to the printer.
Now, which connecting arrows should be activated to see what result??
thanks,
Bernd

Hi Bernd,
I don't know if it is applicable to Painter IX, but Corel posted a color
management tutorial for Painter 8 some time back;

Yes, it's basically the same as the default "Optimized for professional
output" (strange name for offset printing), with a few profiles changed,
most noticeable you have your own monitor profile (Created in Adobe Gamma in
Photoshop). You also use Adobe RGB for the internal RGB (which acts as a
reference for the CM module, right?). Adobe RGB is the largest RGB color
space (i think) and thus you want to use that so you don't loose any colors
that might be in CMYK but not in RGB (some say there are in fact some colors
in CMYK that are not in RGB, but it sounds mysterious to me).
I notice Adobe RGB is not available in the drop down list in Painter IX, so
I have stuck with Generic RGB for now. I guess that is about the same as
sRGB, but where do you find Adobe RGB color profile? I have it in the CM
module i Draw, so why does it not appear in Painters CM module?
Anyway, if you don't have your own monitor profile and so, stick with the
generic ones, they give you a pretty good picture that is a lot more
accurate than if you have CM turned off. Conclusion: if you are painting for
some sort of printing, turn the professional output option on, then your
monitor will show you what your art will look like when printed.

Berndt,
There is a PDF file on Color Management included in Painter IX, it's
probably there in Painter 8 too. Its in the Program files/Help folder and
it's called cm.pdf.

The most important part is that I have my video card set to Gamma 1.8. The
main reason I used is to match Adobe's and Corel's dispalys. Generic 1.8
profile in Corel CD is good enough.

Cyan chromatic can't be dispalyed by monitors, and CMYK yellow is richer.
Adobe RGB has bigger gamut than sRGB, but for those that have not idea what
they are doing while converting to CMYK, sRGB is better because less clipped
is produced.

You have to own some Adobe product that has it available, you could also
search the web and look for a profile based on Adobe RGB that you can free
download. Anyway if you have not a deep knowladge about CMYK conversion and
fine tunning, sRGB is a better choice.
I have it in the CM

I am waiting my Painter IX copy, so I can't tell why it doesn't show in your
system.

Approximately, because CM's aren't 100% reliable.

Thanks for the help, all.
I have set my general RGB to ECI RGB (apparently the biggest RGB) now, the
processing to Euroscale Uncoated from Photoshop and the monitor to own
calibrated profile: looks basically like my Photoshop setup which is what I
wanted.
best,
Bernd
