Section 2: Evaluating Color Laser Printers
Evaluating Print Quality
Beauty lies in the eye of the beholder, but there are specific attributes you can
look for to determine the quality of the print output delivered by a color printer.
Color consistency, color calibration capabilities, and advanced color matching are all key
components to the ability of the printer to deliver the consistent, reliable print quality
your company demands.
Look for color consistency
In sample print runs, watch for uniformity
and consistency in large areas of solid fill.
Check for smooth transitions where edges
meet. Also, monitor image quality and
color consistency from page to page dur-
ing longer print jobs, particularly after 100
or 200 prints of the same image. Does the
printer perform periodic automatic calibra-
tion to maintain print-to-print consistency?
Include a variety of elements in your
test pages
Try color graphics, photo images, adjacent
primary colors, large areas of solid color,
color blends and gradients and text in vari-
ous fonts, sizes and colors.
Check source file and platform
compatibility
Can the printer handle the versions of PCL
or Adobe PostScript that your software
might produce? Some popular graphic
applications, such as Adobe Photoshop
Adobe InDesign
, or Adobe Illustrator
®
depend on true PostScript compatibility
for the best color quality and most accu-
rate proofing capability.
Consider the range of color
management capabilities
Look at the depth and breadth of color
management capabilities – is the printer
compatible with the most common industry
standards (assuring you of image fidelity
from screen to print)? Look at the ability to
match color from different devices, i.e. copier,
digital press, printing press or web pages.
How the Phaser 7760 exceeds
the print quality requirement:
Color quality has to do with much more
than just counting dots on the page. The
Phaser
7760 printer blends the best
®
technologies from previous Phaser printer
products to provide superior color print
quality, meeting the expectations of the
most demanding color professionals and
graphic artists.
Color consistency
Xerox is the company that invented
xerographic printing, and since that time
has remained a leader in the continuous
improvement of that technology. The lat-
est improvement is the invention of Emul-
sion Aggregation (EA) toners. This toner
technology is a chemical process that
"grows" very small, very consistently sized
toner particles – rather than mechanically
grinding them – to product very fine color
detail and smooth transitions.

Automatic density control assures consis-
®
tent color from the first print to the one-
hundredth to the one-thousandth.
For the demanding color professional,
PhaserCal
allows instrumented routine
®
calibration and comes standard on all
configurations of the Phaser 7760.
Mixed elements
When your document includes mixed ele-
ments such as graphics, text and photos
– the Xerox-exclusive Automatic TekColor
setting applies the best color correction
to each graphic element on the page.
This assures you get the sharpest text, the
brightest colors and the life-like images
from your original file. A new feature in
the Phaser 7760, called "black trapping,"
improves the look of black text printed
against a color background, and of color
text printed against a black background.
Platform compatibility
No matter who on your network needs to
print, the Phaser 7760 has them covered.
Drivers include:
• True Adobe
PostScript
®
driver) to take full advantage of your
printer's custom features
• A PCL
driver can be used for applica-
®
tions requiring PCL
• Xerox Walk-Up Printing Driver (for Win-
dows) enables printing from a PC to any
Xerox PostScript-enabled printer. This is
especially helpful to mobile profession-
als who travel to multiple locations and
need to print to different printers.
• Macintosh
OS driver (OS 9.x or OSX
®
10.1 or higher)
• Unix drivers (Linux, Solaris™)
