Image Previews options (Mac OS)
Saves thumbnail data for the file. Thumbnails display
in the Open dialog box. You can set these image preview options: Icon to use the preview
as a file icon on the desktop, Full Size to save a 72-ppi version for use in applications that
can only open low-resolution Photoshop images, Macintosh Thumbnail to display the
preview in the Open dialog box, and Windows Thumbnail to save a preview that can
display on Windows systems. Keep in mind that Windows thumbnails increase the size of
files as delivered by Web servers.
Use Lower Case Extension (Windows)
Makes the file extension lowercase.
File Extension options (Mac OS)
Specifies the format for file extensions. Select Append
to add the format’s extension to a filename and Use Lower Case to make the extension
lowercase.
Important:
To display image preview and file extension options when saving files in Mac
OS, select Ask When Saving for the Image Previews option and the Append File Extension
option in the Preferences dialog box. For more information, see
“Setting preferences for
saving files (Photoshop)” on page 463
.
Saving files in Photoshop EPS format (Photoshop)
Virtually all page layout, word processing, and graphic applications accept imported or
placed EPS (Encapsulated PostScript) files. To print EPS files, you must use a PostScript
printer.
To save a file in Photoshop EPS format:
1
Save the artwork, and choose Photoshop EPS from the Format menu. (See
“Saving files”
on page 446
.)
2
In the EPS Options dialog box, select the options you want, and click OK:
Preview
Creates a low-resolution image to view in the destination application. Choose
TIFF to share an EPS file between Windows and Mac OS systems. An 8-bit preview delivers
better display quality but larger file size than a 1-bit preview.
Note:
To use the JPEG preview option in Mac OS, you must have QuickTime installed.
Encoding
Determines the way image data is delivered to a PostScript output device:
Choose ASCII if you’re printing from a Windows system, or if you experience printing errors
or other difficulties.
•
Binary produces a smaller file and leaves the original data intact. Choose Binary
encoding if you’re printing from a Mac OS system. However, some page-layout applica-
tions and some commercial print spooling and network printing software may not
support binary Photoshop EPS files.
•
JPEG compresses the file by discarding some image data. Files with JPEG encoding can
be printed only on Level 2 (or later) PostScript printers and may not separate into
individual plates.
Include Halftone Screen and Include Transfer Function
Control print specifications for
high-end commercial print jobs. Consult your printer before selecting these options.
Transparent Whites
Displays white areas as transparent. This option is available only for
images in Bitmap mode.
