SmartNote: 35
Type: Term

ColorSync

SmartNote: 37
Type: Utility
ColorGeek factor:
ColorSync is Apple?s color management standard and framework which has been built into the Mac OS for years.
ColorSync is a standard method for developers to call the operating system when they want their programs to correctly manage color. There are also provisions in ColorSync that allow developers to write their own Color Matching Methods and also for the users to select different ICC profiles to use. In some sense, ColorSync is the glue that holds it all together, but it is also a standard, one that ships with every copy of Mac OS. That reassures developers, and end users alike that it will be present in their users? systems and solutions can be built around it.

Real World Photoshop 6

SmartNote: 352
Type: Book
ColorGeek factor:
By Bruce Fraser and David Blatner

Photoshop 5.x is probably the first major publishing application to bring ICC color management to the masses (as in BIG groups of people). Photoshop 6.x has been upgraded to smooth out the complexities of managing color and offer powerful new features.

As with the "Real World Photoshop 5", these guys have written a great book that is indispensible as far as setting up and using Photoshop correctly so you get the expected results.

Profiling Monitors with ColorSync

SmartNote: 353
Type: TechTip
ColorGeek factor:
ColorSync 2.5 and later allows you to calibrate and profile your monitor by eye, with no special tools, and for free. This is not as accurate as calibrating and profiling using a colorimeter but it is considerably better than no profile at all. In fact, Performing this "by eye" can take into consideration ambient lighting conditions which hardware-based methods often do not.


To get started:



  • Go to Apple's ColorSync website and download the latest version of ColorSync
  • Install it
  • Go to your "Monitors and Sound" control panel and click on the "Color" button.
  • Click on the "Calibrate" button and follow the calibration and profiling guide.

At the end of the process, name and save your profile into the "ColorSync Profiles" folder in your "System Folder" and you"re done. Or perhaps more correctly, you"ve just begun.

Finding the Right Profile

SmartNote: 361
Type: TechTip
ColorGeek factor:
Profile Central is constructed to allow you to search for profiles in three ways: By service provider, by service, or by device.

If you are looking for a specific service-providing company, then either their name or click the "Browse" button to browse through the list. Once you find the service provider you are looking for, click on their name and you will be taken to their detail page. On that page are listed the different services they perform, the associated profiles and also a list of all the profiles they have contributed.

If you are looking for a service, just check the box next to the desired service and Profile Central will return a list of service providers who offer those services. When you have found the provider you want, click on their name and follow the above instructions.

If you are looking for profiles by device, check the boxes beside the desired device types and click "Search". Profile Central will return a list of profiles for each of the selected device types. Clicking on the profile name will take you to the Profile Detail page. See the link below for the next steps

Downloading and Installing Profiles

SmartNote: 362
Type: TechTip
ColorGeek factor:
Once you have found the profile you want, click on its name and you will be shown the Profile Detail page. This page will supply you with detailed information about how the profile was created, which device it describes, and settings / substrates used in its creation (and which should be used along with the profile in order to get the best results)

Click on the "Download" button to begin the download process. You will need to sign into the membership area (or become a new member and then be taken there) to begin the download.

Once in the download area, click on the profile name and the download will begin.

When the download is completed, ensure the profile has been unpacked and decompressed correctly and then move it into the appropriate folder / directory:

- For Mac users
- If you are using ColorSync 2.1 or earlier, install the profile into the "ColorSync Profiles" folder in the "Preferences" folder within your "System, Folder"
- If you are using ColorSync 2.5 or later, the "ColorSync Profiles" folder has been moved up one level to the root level of the "System Folder"
- If you are using MacOS 8.5 or later, you can drop profiles right onto the "System Folder" icon and the Finder will route the profile into the correct folder automatically.

For Windows users:
- Place all the *.ICM files in the 'Windows\System\Color' folder.

You are now ready to start using the profiles. Some programs (like Photoshop 5.x) may need to be quit and restarted if they were running when you installed the profiles.

ColorGeek factor: unrated
Edit is a 64-Bit, ICC-Dependent Application For Editing Images Via Input Or Output Profiles.

ColorBlind Edit is a powerful color-correction and image enhancement application that allows you to edit images via attached ICC profiles without affecting the actual raw data. With ColorBlind Edit, you can apply various tonal curve corrections and global and selective color corrections in device-independent color space.

Image Acquisition:

ColorBlind Edit supports all scanners with an acquire module. Images can also be acquired via a "Hot" folder from anywhere on your network. Images saved on disk can also be opened. The application opens and saves in TIFF, EPS, DCS, and Scitex CT formats.

With ColorBlind Edit, you attach ICC source and color edit profiles to an image for processing with other ICC aware applications, or you can process the image to the desired color space, depending on your selected output profile.

Image Display:

Fast, accurate RGB, LAB, and CMYK image display is achieved through constant use of ColorSync 2.0 monitor profiles within the application. Output color space can be simulated in the display.

Image Processing:

Profiles and corrections can be applied at the host workstation or via any application
compatible with ColorSync 2.x

Batch Processing: (see ColorBlind Edit Server)

Any or all image acquisitions, profile attachments and editing can be applied in a batch mode. Batches can be customized in any configuration to perform all or part of your image processing work.
