What color space is used for the working space for CDGS

Hi Everybody,
1.   What color space is used for the working space (aka Central Space, Intermediate Space, etc.) in CDGS.


The dialog lists a "default" space which I assumed was to be used for untagged documents.  So where is the color space of the working space set.


If default refers to the working space, then what space is assigned to untagged documents.

That was the beauty of the old diagram. The working space) was centered in the middle of the diagram and you chose a color space for it.

2. What profile is being assigned to the document and to the working space when switching spaces from the menu.  The profiles must obviously change when switching from RGB to Lab or to CMYK.

  • Ok assuming that you have created or opened a document that matches the application settings and assuming North American General purpose settings.

    The first this to remember is that all spaces will be converted to or simulated to your Windows display profile for viewing only, as the application automatically uses the display profile from Windows.

    WORKING SPACES. The internal RGB and the RGB is sRGB, the grayscale is 20% dot gain and the CMYK is US Webcoated V2. The default set are the working spaces for the application, a document can have a different set of working spaces then the application, they are under the tools menu color management document. A new document will use the application defaults unless you choose otherwise.

    With default settings

    Opening untagged documents will assign the application defaults to that documents as will importing untagged documents.

    Opening tagged documents uses the embedded profile, independent from the application defaults, as will importing tagged documents.

    Importing tagged documents that do not match the current documents color spaces will convert all RGB and Grayscale to the current documents color spaces and assign the CMYK numbers to the current documents CMYK color space.

    Tagging during exportation and saving are handled on a document level, IE centered on the documents color spaces NOT THE APPLICATION.

    With a document open you can change the application defaults from the default menu WITHOUT AFFECTING the open document.

    With an open document you can change the documents color spaces ONLY FROM THE DOCUMENT COLOR MANAGEMENT MENU.

    Once a CD file has been created and saved any image imported into CD will retain the color space on the CD document when you edit it in PP and return it to CD, regardless of the default color management settings in PP.

    Saving untagged documents are exactly that, untagged, the color numbers travel with the document but are meaningless until assign a profile in the destination application.

    CorelDRAW include several pre-made se of the most common color configuration. The "working space" is relative to the preset you choose. Of course you can customize each one and save with a new name if you want

    "Default" is the color profile of the current set. For example, if you choose "Europe PrePress", the "defaults" are AdobeRGB for RGB, ISO Coatedd v2 for CMYK, 15% Dot gain for Grayscale, etc There's not only one "default" and that's only the saved configuration. if you save a new color profile, ie sRGB instead AdobeRGB, it will become the new "default"

    That's relative to the options you choose (on the right side of the color management dialog)

    That's your point of view only. The old diagram only includes RGB color space on the center, and you should do an extra step yo choose Rendering intent (then, most users never discover it). The CMYK color space was on the right side, and that seems not so important, but if it's for print, it should be the main option. The problem with the old diagram was that most users don't understand it. For example, there was a RGB color profile on the center but some people confuses it with the monitor at the bottom. Also, there're some "default" profiles without know what means: "Generic internal color profile", "Generic offset separation profile", etc. Then, if you ask to some users "What color profile are you using on your document?" the most common answer was "Generic". Right, but what does means? What color profile was the "Generic offset separation profile"? it was a color profile for coated paper or uncoated? what total ink is using? it was applied to the image when you import it or teh image maintain their color profile? The old color diagram create more confusion and doubts than answers. Most users just choose "optimized for proffesional output" "Optimized for web" or even... "Default settings". But what was those "Default settings"?

    Under Tools / color management / document settings you have the option for "Assign different color profiles" or "convert document to the new color profiles". 

  • Hi David and Ariel,
    Thanks for the reply.  However:
    Unless Photoshop X7 is different than Photoshop X6, you did not answer the question.  Here's the color management dialog.  It clearly says that the defaults apply only to the document.  There does not seem to be an entry for the working space.  That's a serious omission for the people (not me) who believe that Adobe 1998 is the best working space to use.
