Printing
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 these situations, you can select the
ASCII encoding method. However, ASCII files
contain about twice as many characters and
require about twice as much time to transfer as
binary files. (See “Photoshop EPS format” on
page 250.)

To change the encoding method:
1
Choose File > Print Preview, or click the Print
Preview button in the shortcuts bar.
2
Select an option from the Encoding menu.
Using color management when
printing
printing
Understanding when to use color management
requires an understanding of how colors are repre-
sented in digital images. Photoshop Elements uses
a grid of elements known as pixels to represent
images. When you view an image on your monitor,
pixels are displayed using red, green, and blue
light. When you print an image on a desktop
printer, pixels are reproduced using colored inks.
The number of inks used in the printing process,
as well the exact color value of each ink and the size
of the dots printed, are determined by the printer
manufacturer.

Because your monitor operates in a different color
space than your printer, and different printers
have different color spaces, the colors you see on
your monitor can vary drastically from those in
the printed image. Color management provides a
solution to this dilemma. In a color-managed
workflow, you use color profiles to ensure that the
colors remain consistent. (See “About color and
computer graphics” on page 65.)

Converting colors to a different color space usually
involves an adjustment of the source or image
colors to accommodate the gamut of the desti-
nation printer or output device color space.
Different translation methods use different rules
to determine how the source colors are adjusted;
for example, colors that fall inside the destination
gamut may remain unchanged, or they may be
adjusted to preserve the original range of visual
relationships as translated to a smaller destination
gamut. These translation methods are known
as rendering intents because each technique is
optimized for a different intended use of
color graphics.

To determine if you need to use color management
when printing:
1
Print an image without color management.
2
Compare the colors in the printed image with
those on your monitor. If the color fidelity is not
acceptable, use color management.
