Is your system V4-ready?
We have a simple test you can use. The two test pages provided
here (one in HTML, one in PDF) have ICC Version 4 profiles embedded
in their image data.
The test pages demonstrate how various applications, such as your
browser or PDF viewer, handle Version 4 ICC profiles.
Follow these steps:
- Verify that your application settings haven't disabled color
management. The preferences may include options for turning color
management on, and for preserving profiles embedded in documents. See
your application documentation for how to do this. Many applications
lack user settable controls for color management.
- Open one or both of these pages in the application you want to test.
- If possible also print these pages, as your printing system
doesn't always match the abilities of the application.
- Compare the test image with the example results shown on the test
page, to determine if your system is using the profiles correctly.
If the application doesn't display or print the pages correctly,
first verify again that you have not disabled color management, then
check with your vendor for available upgrades. Some applications
provide their own color management, while other applications use
operating system services, such as ICM or ColorSync. In the latter
case you may need to upgrade the operating system.
You can also test your image editing applications using the images
that make up the test image. Using your browser save each part of the
test image to disk as a separate image file, then follow the steps
This test is not exhaustive. For example, it doesn't test CMYK
profiles, and it doesn't test all possible contexts where ICC
profiles are used, such as monitor profiles.
This test does not test that your system is properly calibrated. It
generates an extremely big difference between correct and incorrect
colors, enabling you to evaluate the results even if your system is
not properly calibrated.
