Section 2: Evaluating Colour Laser Printers
Evaluating Print Quality
Beauty lies in the eye of the beholder, but there are specifi c attributes you
can look for to determine the quality of the print output delivered by a colour
printer.
Colour consistency, colour calibration capabilities and advanced colour
matching are all key components to the ability of the printer to deliver the consistent,
reliable print quality your company demands.
Look for colour consistency
In sample print runs, watch for uniformity
and consistency in large areas of solid
fi ll. Check for smooth transitions where
edges meet. Also, monitor image quality
and colour 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 colour graphics, photo images,
adjacent primary colours, large areas of
solid colour, colour blends and gradients
and text in various fonts, sizes and
colours.
Check source fi le 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
®
Illustrator
, depend on true PostScript
compatibility for the best colour quality
and most accurate proofi ng capability.
Consider the range of colour
management capabilities
Look at the depth and breadth of colour
management capabilities – is the printer
compatible with the most common
industry standards (assuring you of image
fi delity from screen to print)? Look at the
ability to match colour from different
devices, i.e. copier, digital press, printing
press or web pages.
How the Phaser 7760 exceeds
the print quality requirement:
Colour 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 colour print
quality, meeting the expectations of the
most demanding colour professionals
and graphic artists.
Colour 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 fi ne colour detail and smooth
transitions.
Automatic density control assures
®
consistent colour from the fi rst print
, or Adobe
to the one-hundredth to the one-
thousandth.
For the demanding colour professional,

calibration and comes standard on all
confi gurations of the Phaser 7760.

allows instrumented routine
Mixed elements
When your document includes mixed
elements such as graphics, text and
photos – the Xerox-exclusive Automatic
®
TekColor
setting applies the best colour
correction to each graphic element
on the page. This assures you get the
sharpest text, the brightest colours and
the life-like images from your original
fi le. A new feature in the Phaser 7760,
called "black trapping," improves the look
of black text printed against a colour
background, and of colour 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

driver) to take full advantage of your
printer's custom 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
different printers.

• Unix drivers (Linux, Solaris™)
