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, moni-
tor image quality and color consistency from page
to page during longer print jobs, particularly after
100 or 200 prints of the same image. Does the
printer perform periodic automatic calibration 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 various 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 accurate 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 expec-
tations of the most demanding color profes-
sionals 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 latest improvement is the
invention of Emulsion 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 consistent
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
®
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
®
to take full advantage of your printer's cus-
tom features
• A PCL
driver can be used for applications
®
requiring PCL
• Xerox Walk-Up Printing Driver (for Windows)
enables printing from a PC to any Xerox
PostScript-enabled printer. This is especially
helpful to mobile professionals who travel to
multiple locations and need to print to differ-
ent printers.
• Macintosh
OS driver (OS 9.x or OSX 10.1
®
or higher)
• Unix drivers (Linux, Solaris™)
