Photoshop Video Tutorials - Learning the Ropes of Photoshop
In order to have a fully color controlled environment you must have all devices displaying or printing color, profiled. How is this accomplished? Color
management software (CMS) takes readings from your specific devices and compares their color with reference files of what color "should be" as
defined by the ICC. For example, to profile a scanner you would scan in what is called an IT8 target. This scan is then compared with a reference file
by the CMS. The differences between what the reference file says the color should be, and what the color your device actually output is meat of the
profile. Basically, a profile says what's not perfect about your particular device. If your scanner always seems to scan things in a little green, or your
printer always seems to print things with a magenta cast-these are the things that are taken into account when color profiling your devices. To
complicate matters a little further, this process also takes into account the differences in color between various paper and ink combinations.
This is where professional level CMS's and entry level ones differ. At this point with the entry level you will scan in the printed target and the CMS will
actually use the before generated scanner profile to correct the scan, so it can the correct your printed target. A professional level CMS will have a
separate hardware device designed specifically for reading printed media targets.
Okay, now that we've created all of the profiles, time to implement them. You monitor profile should be getting applied upon startup by your operating
system, so let's move on to your scanner. Scan in an image-once again using the exact same settings that were used to create the profile (other than
resolution). In Photoshop choose Image Menu>Assign Profile. Then choose Profile: Your Scanner Profile. Having done all of the previous steps in
Photoshop correctly, you should now be amazed at how your image colors changes to appear incredibly like the original t
