Adobe Photoshop Help Using Help | Contents | Index Producing Consistent Color (Photoshop) Back 116 Embedding profiles in saved documents By default, a tagged document will have its profile information embedded upon saving in a file format that supports embedded ICC profiles. Untagged documents are saved by default without embedded profiles. You can specify whether or not to embed a profile as you save a document; you can also specify to convert colors to the proof profile space and embed the proof profile instead. However, changing the profile-embedding behavior is recommended only for advanced users who are familiar with color management. To change the embedding behavior of a profile in a document: 1 Choose File > Save As. 2 Do one of the following: • To toggle the embedding of the document's current color profile, select or deselect ICC Profile (Windows) or Embed Color Profile (Mac OS).This option is available only for the native Photoshop format (.psd) and PDF, JPEG, TIFF, EPS, DCS, and PICT formats. • To toggle the embedding of the document's current proof profile, select or deselect Use Proof Setup (available for PDF, EPS, DCS 1.0, and DCS 2.0 formats only). Selecting this option converts the document's colors to the proof profile space and is useful for creating an output file for print. For information on setting up a proof profile, see "Softproofing colors" on page 113. 3 Name the document, choose other save options, and click Save. Obtaining, installing, and updating color profiles Precise, consistent color management requires accurate ICC-compliant profiles of all of your color devices. For example, without an accurate scanner profile, a perfectly scanned image may appear incorrect in another program, simply due to any difference in color space between the scanner and the program displaying the image. This misleading representation may cause you to make unnecessary, time-wasting, and potentially damaging "corrections" to an already satisfactory image. With an accurate profile, a program importing the image can correct for any gamut differences and display a scan's actual colors. Once you obtain accurate profiles, they will work with all applications that are compatible with your color-management system. You can obtain profiles in the following ways, with the most precise methods listed first: • Generate profiles customized for your specific devices using professional profiling equipment. • Use the settings in the Custom CMYK dialog box to describe your device, and then save the settings as a color profile. (See "Creating custom CMYK profiles" on page 121.) • Obtain a profile created by the manufacturer. Unfortunately, such profiles do not account for individual variations that naturally occur among machines (even identical modes from the same manufacturer) or from age. • Substitute an available profile that may be appropriate for the device's color space. For example, many Mac OS scanners have been optimized for an Apple RGB monitor color space, so you might try using an Apple monitor profile for these devices; for a Using Help | Contents | Index Back 116
