EPS files can contain Open Prepress Interface (OPI) comments, which let you use fast, low-
resolution versions (proxies) of images for positioning on a page. For final output, either
InDesign or your prepress service provider can automatically replace the proxies with high-
resolution versions.
When you place an EPS graphic and select Show Import Options, you'll see a dialog box
containing these options:
Read Embedded OPI Image Links This option tells InDesign to read links from OPI
comments for images included (or nested) in the graphic.
Deselect this option if you're using a proxy-based workflow and plan to have your service
providers perform the image replacement using their OPI software. When this option is
deselected, InDesign preserves the OPI links, but does not read them. When you print or
export, the proxy and the links are passed on to the output file.
Select this option if you're using a proxy-based workflow and you want InDesign, instead
of your service provider, to perform image replacement when you output the final file.
When you select this option, the OPI links appear in the Links palette. (See
how graphics print" on page
Also select this option when you import EPS files containing OPI comments that are not
part of a proxy-based workflow. For example, if you import an EPS file containing OPI
comments for an omitted TIFF or bitmap image, you'll want to select this option so that
InDesign can access the TIFF information when you output the file.
Apply Photoshop Clipping Path Select this option to import a clipping path from
a Photoshop 4.0 and later EPS file, which you can later edit in InDesign.
Proxy Generation This creates a low-resolution bitmap representation of an image
when drawing the file to the screen. The following settings control how the proxy will
be generated:
Some EPS images contain an embedded preview. Select Use TIFF or PICT Preview to
•
generate the proxy image of the existing preview. If a preview does not exist, the proxy
will be generated by rasterizing the EPS to an offscreen bitmap (the quality of the
bitmap is dependent on the quality of the embedded preview).
Select Rasterize the PostScript to ignore the embedded preview. This option is typically
•
slower but provides the highest-quality results.
Note: All instances of the imported file share the proxy setting when more than one single
file is imported into the same document.
GIF (.GIF)
Graphics Interchange Format (GIF) is a standard for displaying graphics on the World Wide
Web and other online services. Because it compresses image data without losing detail, its
compression method is called lossless. Such compression works well with graphics that
use a limited number of solid colors such as logos and charts; however, GIF cannot display
more than 256 colors. For this reason it is less effective for displaying photographs online
(use JPEG instead) and is not recommended for commercial printing. If an imported GIF file
contains transparency, the graphic interacts only where the background is transparent.
