ADOBE PHOTOSHOP 5.0
User Guide
For optimal output on a PostScript printer, the
image resolution should be 1.5 to 2 times the
halftone screen frequency. If the resolution is more
than 2.5 times the screen frequency, an alert
message appears (see “About image size and
resolution” on page 42). If you are printing line art
or printing to a non-PostScript printer, see your
printer documentation for the appropriate image
resolutions to use.
7 To save your halftone screen settings for use
with other Adobe Photoshop files, choose from the
following options:
• To save the settings, click Save in the Halftone
Screens dialog box. Name and save the settings.
• To save the new settings as the default, hold
down Alt (Windows) or Option (Mac OS), and
click the —> Default button. To return to the
original default settings, hold down Alt/Option
and click <—Default.
8 To load settings for use with another Photoshop
file, click Load. Locate and select the settings.
Additional printing options
You can also set printing options by using the Print
dialog box, which appears when you choose File >
Print (Windows), or when you choose File > Print
and then choose Adobe Photoshop 5.0 from the
dialog box menu (Mac OS). These options let you
print only a selected area of an image, print
multiple separation files, and transfer image data
to the output device in ASCII format. The
appearance of this dialog box varies with different
printers.
Printing a selected area To print part of an image,
use the rectangular marquee tool to select the part
of an image you want to print. Then choose File >
Print, and select the Print Selected Area option.
Printing separations By default, a single page is
printed for CMYK and duotone images. For Space,
choose Separations to print a separate page for
each color.
Printing with print spoolers and across networks
By default, the printer driver transfers binary
information to printers. However, some print
spooler programs, computer networks, and third-
party printer drivers don’t support files that are
binary or JPEG-encoded, and some PostScript
output devices accept binary and JPEG-encoded
image data only through their AppleTalk and
Ethernet ports, not their parallel or serial ports. In
addition, only PostScript Level 2 (or higher)
output devices support JPEG encoding. Sending a
JPEG-encoded file to a Level 1 output device may
result in PostScript language errors.
In these situations, you can transfer the file by
selecting ASCII in the Print dialog box. However,
ASCII files contain about twice as many characters
and require about twice as much time to transfer
as binary files.
