Color management and Adobe Photoshop

off so the same conditions the profile gets generated under will apply to each consecutive scan.

At this point you will scan in the IT8 target, most likely at 200 dpi, and save the file. Some CMS's will have you scan the IT8 target out of their own interface, but I would recommend scanning the target with the same application that you will be using in the future-if possible. When scanning into an application like Photoshop, remember to save the image without any profile attached (in Photoshop when saving you will see a checkbox under Save Options

>Color that is labeled ICC Profile-make sure this is not checked). Now load this image into your CMS, it will take this image and calculate the differences between what your scanner sees compared to what the colors of the IT8 "really" are.

Step Three: The Printer

Now, the last piece to the puzzle, printer targets. Like transparent IT8 targets, printer targets are more complex. Similar to film, different papers or media can produce incredibly different color results. This has to be taken into account in the profiling stage. When creating a printer profile, you are essentially creating a description of the differences between what is ideal color and what is the result of the specific paper/ink/quality setting you choose. A profile created for a professional glossy photo paper will generally not produce good results if used to print on a matte heavy weight paper. The same holds true for differences in ink or quality/speed settings.

In your CMS you should be given the option to save your printer target for printing within your chosen graphic app. If asked choose not to apply a profile when opening. In Photoshop choose File>Print with Preview. Change the Output dropdown to Color Management. Under Source Space choose Document. Under Print Space choose Profile: Same as Source. You are now set up in Photoshop to print your profile target. You aren't done yet! Now go into your printer driver software and set any color options to none, or zero, or whatever shuts off any color changes by the driver. Now print your target.

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.

Step Four: Utilizing the Profiles

Okay,
