Lesson 3. Color Management and Distribut... > Opening a file with an embedded prof...

Opening a file with an embedded profile

Now you will open a scanned image with an embedded profile. You’ll convert the image to CMYK mode so that you can add it later to the page layout in Illustrator.

Choose File > Open and open the Lotus.tif file, located in the Lessons/Lesson03/03PSD folder on your hard drive. The Embedded Profile Mismatch dialog box appears.

The document was saved with a profile of the scanner’s color space that differs from the current RGB working space.

It’s important to preserve the embedded source profile because in a color-savvy application like Photoshop, the source profile defines the originating colors to ensure that colors are displayed and managed correctly throughout the workflow. However, some scanners can impose a color cast. If a file needs significant editing, it should be converted to the working space (here, for example, the much larger Adobe RGB space) for the color corrections. In this case, the file doesn’t require additional color correction.

Choose Use the Embedded Profile (Instead of the Working Space). Click OK.

Resize the artwork by choosing Image > Image Size. Resize the image to match the resolution of the other images used in the postcard by entering 200 ppi, the same resolution of the background image. Click OK.

You’ll take a look at the document’s color space. Photoshop features a few clues that can help you quickly identify the color space of a file, as well as the current working space.

Choose Document Profile from the File Info bar at the bottom of the document window to display the file’s color space. (If necessary, expand the image window to view the File Info bar.)

If a document’s color space differs from the default working space, as the example shows, an asterisk symbol (*) appears in the title bar. A pound symbol (#) in the title bar indicates that the image is missing a color profile.

Soft-proof the image if desired. For instructions, see “Soft-proofing an image” on page 82.

Convert the image to the CMYK color space by following steps 1 through 6 in “Color-separating an image” on page 84.

Choose File > Save As, and navigate to the Lesson03/03PSD folder. For format, choose Photoshop, and select Embed Color Profile. Rename the file Lotus_CMYK.psd. Click Save.

Close the file.

You’ll continue work on this project in Illustrator, and return to Photoshop later to prepare the artwork for use in a Web page.

If desired, quit Photoshop. You can also leave the application running for use later in the lesson.
