coreldraw 10 color management

Where can I find some practical experience with detail explanations on how to work on the color management dialog box in Coreldraw 10. I’ve got questions on making choices in the advance settings and profiles.

Hello Elinglim, Welcome to Talk graphics.
Post your specific questions, then if anyone can answer, I am sure they will post a reply.

Thank you Mike, I try to write down some of my queries, sorry for they may be stupid and clumsy.

Here are my problems in choosing a profile:

In choosing a profile, does it differ much if I use a generic one rather than a custom device profile? For instant, my desktop printer is Canon BJC-6200, do I really need to try my very best to find a tailor-made device profile (that may be time consuming and frustrating) , or a generic one is good enough ? (if I can accept a bit deviation in colors, of course not too much)

However , if I choose generic profiles for the Internal RGB, composite printer, and separation printer, and the monitor (not tailor-made ones), will the outcome unacceptable? You know a bit deviation + a bit + a bit…….., that may be great differences, is it true, do anyone have the experience?

By the way , what is this Internal RGB? Isn’t it a neutral color space? Why is it RGB, not CMYK or CIE? What criteria should I use in choosing profile for this Internal RGB? There are lots of profiles in the pull-down menu , what’s their differences? How to make a right choice?

I still got some problems on the advance setting part :

If I choose a printer, then a color profile in Advanced printer setting, is this color profile I pick will automatically override the one I pick in the profile selection pull-down? If I choose “do not override� rather than a color profile, does it mean that the one I pick in the profile selection pull-down will automatically become the selected color profile for the printer?

If I have made a choice of color profile for my printer in the color management dialog box, do I still need to check the box “Apply ICC profile (generic CMYK printer profile)� in the Misc page of File > print? What if I just leave it blank, what profile will be applied to my printer?
My desktop printer is Canon BJC-6200, in the advanced printer setting, I got two choices for my printer as color profile , one is named “Canon Inc- BJC color printer�, the other one is the “generic CMYK printer profile�, which one is better? Or should I find a Canon BJC-6200 color profile somewhere? Where can I go get these profile?


Lastly,is it that some service bureaus have their own CMS , that I only need to provide them the document, they will save my effort and do the color matching for me? How’s the outcome, will it be surprisingly good , or bad? I am afraid that after putting so much effort into the CMS myself, I still can’t guarnantee a good outcome when the document flows into the service bureau’s hands.

To the best of my knowledge, the color profile fine tunes your hardware to match scanned images, screen colors, and printer colors accurately, there will always be some deviation do to lighting, paper, ink quality etc....

Color space is a geometric representation to the extent that all the colors in a devices color range are plotted as points on color models like RGB.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> Why is it RGB, not CMYK or CIE? <HR></BLOCKQUOTE>

The Devices, printer, monitor, scanner use RGB.

CIE stands for Comission Internationale de l'Eclairage (International Commission on
Illumination). The commission was founded in 1913 as an autonomous international board to provide a forum for the exchange of ideas and information and to set standards for all things related to lighting. As a part of this mission, CIE has a technical committee, Vision and Color, that has been a leading force in colorimetry
since it first met to set its standards in Cambridge, England, in 1931.

Refer to this web site for an in depth explanation of color management, it is very informative.

The devices listed in the program that match your equipment are already profiled for you, using those listed that closely represent the equipment in your system should produce satisfactory results.

Yes, I believe the advanced settings will over-ride the system profile for the printer for that print job.

The device profile is stored in the ICC(International Color Consortium) standard .ICM file on your hard drive. If you choose a generic profile in the print dialog then the color managment profile will probably be ignored.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> What if I just leave it blank, what profile will be applied to my printer? <HR></BLOCKQUOTE>

The default setting should apply.

Use the one named Canon Inc. BJC color printer. I believe the model number is irrelevant.

Your color profile is hardware specific, I don't believe it will have any effect on a service bureau's calibration.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> How's the outcome, will it be surprisingly good , or bad?

If the service bureau uses state of the art calibration equipment I think you will get excellent results, although it is a printer that produces the final printed media.

I don't have CD ver.10 manuals and I am not a print specialist, so please understand that the info I have presented is just from common sense, I can't guarantee total accuracy on my part, although I do hope it helps.

Best wishes.
