Adobe Photoshop (.PSD)
You can place Adobe Photoshop 4.0 and later images directly into a layout. When a
Photoshop file is placed in a document, all layers and layer masks are automatically
flattened. These changes affect the file inside the InDesign document only—the original
Photoshop file is not altered. If you save paths, masks, or alpha channels in a Photoshop
file, InDesign can use them to remove backgrounds, or to wrap text around graphics.
Graphics that contain paths, masks, or alpha channels act as transparent objects when
imported and interact only where the background is transparent; see
clipping paths" on page 261
If you embedded an ICC color management profile in an Adobe Photoshop image,
InDesign automatically reads the embedded profile. You can override the embedded
profile while you're importing a file by selecting Enable Color Settings in the Import Image
dialog box. You can also override this profile after you import the file, by choosing Object
> Image Color Settings. These actions will not remove or alter the profile embedded in the
Photoshop image.
BMP (.BMP)
BMP is the standard Windows bitmap image format on DOS and Windows-compatible
computers. However, BMP does not support CMYK, and its color support is limited to 1, 4,
8, or 24 bits. It is less than ideal for commercially printed or online documents, and it is not
supported by Web browsers. BMP graphics can provide acceptable quality when printed on
low-resolution or non-PostScript printers.
DCS (.DCS)
Desktop Color Separations (DCS), developed by Quark, is a version of the standard EPS
format. The DCS 2.0 format supports multichannel CMYK files with a single alpha channel
and multiple spot channels; the DCS 1.0 format supports CMYK files without alpha
channels. InDesign recognizes clipping paths in Photoshop-created DCS 1.0 and DCS 2.0
files.
DCS files are intended to be used in a pre-separated, host-based workflow. If you export to
a composite PDF, EPS, or PostScript
exported; the color separation files are not preserved. It is not recommended to color
separate DCS files in-RIP or from a composite file. DCS files should not be used to create
high-resolution color composite proofs.
EPS (.EPS)
The Encapsulated PostScript (EPS) file format is used to transfer PostScript language
artwork between applications, and is supported by most illustration and page-layout
programs. Typically, EPS files represent single illustrations or tables that are placed into
your layout, but an EPS file can also represent a complete page.
Because they are based on the PostScript language, EPS files can contain both vector and
bitmap graphics. Since PostScript cannot normally be displayed on-screen, InDesign
creates a bitmap preview for an EPS file for on-screen display. If you print a page with an
EPS file to a non-PostScript printer, only this screen-resolution preview will be printed.
EPS allows for prepress-quality resolution, precision, and color. This format includes all of
the color and image data required to color-separate DCS images embedded in the EPS
graphic. EPS isn't ideal for online publishing in HTML, but it works well for online
publishing in PDF.
