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

PostScript

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.

• Macintosh

OS driver (OS 9.x or OSX

10.1 or higher)

• Unix drivers (Linux, Solaris™)
