Saving and Exporting Images
DCS
Desktop Color Separations (DCS), developed by
Quark, is a version of the standard EPS format.
The DCS 2.0 format supports multichannel
and CMYK files with a single alpha channel and
multiple spot channels; the DCS 1.0 format
supports CMYK files without alpha channels.
Both DCS 1.0 and DCS 2.0 support clipping paths.
(See “Saving files in Photoshop EPS or DCS
format” on page 315.)
Photoshop EPS
The Encapsulated PostScript (EPS) language file
format can contain both vector and bitmap
graphics and is supported by virtually all graphic,
illustration, and page-layout programs. The
EPS format is used to transfer PostScript language
artwork between applications. When you open an
EPS file containing vector graphics created in
another application, Photoshop rasterizes the file,
converting the vector graphics to pixels (see
“Importing Adobe Illustrator, PDF, and EPS files”
on page 55).
The EPS format supports Lab, CMYK, RGB,
indexed-color, duotone, grayscale, and Bitmap
color modes, and does not support alpha
channels. EPS does support clipping paths.
For more information on EPS options, see
“Saving files in Photoshop EPS or DCS format” on
page 315.
EPS TIFF or EPS PICT Preview
These formats, which appear as options in the
Open and Open As dialog boxes, let you open
files saved in file formats that create previews but
are not supported by Adobe Photoshop (such as
QuarkXPress
®
). An opened preview file can be
edited and used like any other low-resolution file.
EPS PICT Preview is available only in Mac OS.
Filmstrip
The Filmstrip format is used for RGB animation
or movie files created by Adobe Premiere
®
. If you
resize, resample, remove alpha channels, or change
the color mode or file format of a Filmstrip file in
Photoshop, you won’t be able to save it back to
Filmstrip format. For further guidelines, see the
Adobe Premiere User Guide.
FlashPix
The FlashPix format, developed by Kodak, is
designed to speed the transfer and display of large,
high-resolution files in applications that support
the FlashPix technology. Although Photoshop is
not a FlashPix-optimized application, it can open
and save FlashPix files. The FlashPix format
supports grayscale and RGB color modes, and
does not support alpha channels.
When saving in FlashPix format, you can choose
whether to use JPEG compression. See “JPEG” on
page 323, for information on JPEG compression
options.
