Section 1: Evaluating Tabloid/A3 Color Printers
Print Quality
Many factors determine the quality of the print output delivered by a color
printer.
Printhead technology and image resolution, color registration and accuracy
and intuitive, user-friendly color adjustments are all key components of a printer's
ability to deliver the results you demand to bring your high-end color print jobs in-house.
How the Phaser
7500
®
printer exceeds the print
quality requirement
Color controls
Our Xerox
-exclusive "Color by Words," a
®
powerful-yet-intuitive color technology, takes
the guesswork out of optimizing your color print
jobs. With Color By Words* there is no need to
manipulate source files. Users simply select the
desired color modifications from a drop-down
list—such as "pale green colors a lot more
green" or "red colors a lot more saturated"—
and the image is automatically adjusted.
Color registration and accuracy
With an ASIC driver to control the light intensity
of the LEDs in each printhead, HiQ LED offers
better dot-to-dot intensity and timing control,
and produces more precise color registration.
HiQ LED handles mis-registration issues auto-
matically, simultaneously and continuously,
from LED to LED. In fact, tests show that HiQ
LED technology corrects color mis-registration
even better than comparable laser printers.

Also, with Pantone
-approved color tables, the
®
Phaser 7500 prints specified colors consistently
and accurately, ensuring that the colors you
expect are the colors you get. Plus, true Adobe
PostScript
3™ gives you the power to print
®
visually rich documents reliably.
Plus, text is sharp and readable whether printed
in black on colored backgrounds or in color on
black backgrounds, thanks to the Phaser 7500
printer's Black Trapping feature.
Printhead technology and image resolution
The Phaser 7500 color printer features the new
Xerox
HiQ LED printhead, which offers major
®
improvements in image quality.
In the Phaser 7500 there are four individual
printheads. With each LED array packing 1200
diodes per inch, the printhead can create many
more, and much finer, dots for exceptional reso-
lution, while also saving space in the system's
overall design.

Precise Color Registration
The Phaser
7500 digitally adjusts for
®
®
mis-registration. Notice the white edges on the
"G" and "M" produced by the laser device. The
Phaser 7500 automatically makes the necessary
adjustments.
