CS2 Working Spaces

About working spaces

A working space is an intermediate color space used to define and edit color in Adobe applications. Each color model has a working space profile associated with it. You can choose working space profiles in the Color Settings dialog box.
A working space profile acts as the source profile for newly created documents that use the associated color model. For example, if Adobe RGB (1998) is the current RGB working space profile, each new RGB document that you create will use colors within the Adobe RGB (1998) gamut. Working spaces also determine the appearance of colors in untagged documents. If you open a document embedded with a color profile that doesn’t match the working space profile, the application uses a color management policy to determine how to handle the color data. In most cases, the default policy is to preserve the embedded profile.

About color profiles

Precise, consistent color management requires accurate ICC-compliant profiles of all of your color devices. For example, without an accurate scanner profile, a perfectly scanned image may appear incorrect in another program, simply due to any difference between the scanner and the program displaying the image. This misleading representation may cause you to make unnecessary, time-wasting, and potentially damaging "corrections" to an already satisfactory image. With an accurate profile, a program importing the image can correct for any device differences and display a scan’s actual colors.
A color management system uses the following kinds of profiles: Monitor profiles Describe how the monitor is currently reproducing color. This is the first profile you should create because it is absolutely essential for managing color. If what you see on your monitor is not representative of the actual colors in your document, you will not be able to maintain color consistency. (See To calibrate and profile your monitor.) Input device profiles Describe what colors an input device is capable of capturing or scanning. If your digital camera offers a choice of profiles, Adobe recommends that you select Adobe RGB. Otherwise, use sRGB (which is the default for most cameras). Advanced users may also consider using different profiles for different light sources. For scanner profiles, some photographers create separate profiles for each type or brand of film scanned on a scanner.
Output device profiles Describe the color space of output devices like desktop printers and a printing press. The color management system uses output device profiles to properly map the colors in an document to the colors within the gamut of an output device’s color space. The output profile should also take into consideration specific printing conditions, such as the type of paper and ink. For example, glossy paper is capable of displaying a different range of colors than a matte paper. Most printer drivers come with built-in color profiles. It’s a good idea to try these profiles before you invest in custom profiles.

Why in CS2 edit/colour settings/Working Space do I see, in addition to profiles covering Adobe RGB 1998 (which I use), profiles for my two monitors two printers and scanner plus many other profiles?
Simply put, why should a monitor profile ever be chosen rather than the Adobe RGB 1998 which the Adobe documentation recommends?
Beemer

Never. A monitor profile is suitable for output (you never read from the monitor). Adobe RGB is suitable for input and output.

Mike,

Your answer has not addressed the point of my post.

Jim,

Like Mike your answer doe not answer my question which was why does CS2 offer monitor, printer and scanner profiles in the setting for working space?

I would never use a monitor profile or scanner profile as working space. In a full controlled environment, I can imagine you COULD use a printer profile. But with the softproof capabilities of Photoshop, I doubt it is of much use.

Beemer,

The workspace profiles are industry standards. These standards provide consistency. When files created in colour spaces, say, go to a lab for processing they will know exactly how to handle these files in accordance with the colour space they were created in. The output profiles (monitor, printer etc.) are not industry wide standards in the same way that the colour space ones are. They are peculiar to a particular monitor, printer or even combinations of, and in the case of monitors (and your eyes!)can actually change as the monitor ages. These profiles, when setup correctly merely ensure that what you see on the screen, colours etc., appear as far as possible in the printed output.

I suspect that, in part, it is simply listing all of the profiles in the c:\windows\system32\spool\drivers\color\ directory.

Bruce,

I think you have hit the nail on the head. My underlying reason for asking is that I suspected that at sometime in the past I might have added 3rd party profiles to the XP "color" folder which I should not have and that this is why they are showing up and can actually be selected. Certainly none of the books I have on colour management have ever suggested to use a monitor or printer profile as a working space. In previous photoshop versions working space profiles were kept in a photoshop folder and Windows picked up a copy and put it in the color folder but this does not happen in CS2.

Thanks,

Beemer
