xiii Colorwriter LSR 2000
+
In today’s business environment, the pressure is on to produce professional,
polished documents and sharp, color-specific renderings and presentations.The
pressure is compounded by the need to produce these materials in a fast and cost-
effective manner. Generating them in your own efficient environment results in
higher productivity, especially when crisp output and color quality is of
paramount concern.
About the Colorwriter LSR 2000
+
The Digital Colorwriter LSR 2000
+
represents the highest standards in
continuous tone color laser technology. Equipped with a Fiery

XJe controller,
and combined with Digital’s well-known product reliability and support, the
Colorwriter LSR 2000
+
provides top performance and photographic quality for
large, complex files consisting of text, graphics, and images.The Colorwriter not
only performs at speeds up to five times faster than typical desktop models, it does
so with print quality previously found only in more expensive color laser printers.
With its Adobe

PostScript

level 2 capabilities, Kodak Precision and ICC color
profiles, and flexibility in page layout, the Colorwriter fits extremely well into
graphic arts, prepress, and desktop publishing environments.The complex images
necessitated by computer-aided design and engineering are similarly well met with
this printer’s high-resolution reproduction. Furthermore, word processing
documents, spreadsheets, and other presentations all reflect the highest quality
output when the Colorwriter LSR 2000
+
is the source.
The Colorwriter LSR 2000
+
offers four different color rendering dictionaries
(CRDs) to allow a wide range of color output and to assure that whatever is being
printed looks as it should, from photographs to computer-designed presentations.
Switching between CRDs is effortless; the LCD control panel makes it possible to
use a new CRD without restarting the Colorwriter.The Colorwriter is also
Energy Star compliant, which means it can be left on between print jobs without
wasting electricity. A customizable power saver mode allows the user to specify
when the printer will power-down its mechanical parts. After a brief warmup, the
Colorwriter is ready to receive jobs, allowing you to concentrate on your print
jobs, instead of your printer.

xix Energy Star compliance
Protecting the LCD display
Do not subject the Colorwriter to strong shocks.The Colorwriter has a liquid
crystal display (LCD) that is made of glass and can break. If the display window
breaks and the liquid crystal material leaks out, do not inhale, ingest, or touch it.
If the material gets on your skin or clothing, wash it off with soap and water
immediately.
Ozone emission
This printer meets the requirements for ozone emission of the applicable standard
published by Underwriters’ Laboratories, Inc. (UL). Ozone (O
3
) is a colorless gas
by-productof theelectrophotographic process.Ozoneis dischargedonly whilethe
printer is printing, and is emitted through the exhaust port on the rear, left side of
the printer. Only service personnel should replace the ozone filter.
Those who are particularly sensitive to ozone odor may feel sick if exposed to it for
long periods of time.To avoid this, make sure that the following measures are
taken:
•Install the printer in a large, well ventilated room.
•Avoid facing the exhaust port directly toward users.
•Be sure that the ozone filter is replaced periodically by the service person.
•Avoid using the printer without a filter.
Energy Star compliance
The Colorwriter comes equipped with a power saver mode that can reduce the
total power consumption of the printer to less than 45 watts—a 65 percent
reduction in electricity use. In power saver mode, the fan and fuser are turned off
after a user- defined period of inactivity. With the power saver feature, the
Colorwriter complies with the EPA (Environmental Protection Agency)
guidelines for an Energy Star compliant device (United States only).

1-1 The properties of color
This chapter provides information about:
•The properties of color
•Traditional color printing and Colorwriter printing
•Controlling printed color
The properties of color
Color theory is an attempt to systematize the properties of color perception,
which by nature is relative and changeable. A color appears different depending
on the other colors around it, and individuals vary in their abilities to perceive
color.
This section introduces concepts that are basic to color theory. You will encounter
some of these ideas (such as hue, saturation, and brightness) when you work with
color in applications, while others are useful background information. Since color
is a complex topic, consider this a starting point for experimentation and further
research.
The physics of color
Humans are sensitive to electromagnetic radiation at wavelengths between 400
nanometers (purplish blue) and 700 nanometers (red).This range is called the
visible spectrum of light. We see pure spectral light as intensely saturated or pure
colors. Sunlight at mid day, which we perceive as white or neutral light, is
composed of light from across the visible spectrum in more or less equal
proportions. Shining sunlight through a prism separates it into its spectral
components, resulting in the familiar rainbow of colors (plate 1).
Most light sources we encounter in our daily environment are like the sun in that
they emit a mixture of many light wavelengths, although the particular
distribution of wavelengths can vary considerably. Light from a tungsten light
bulb contains much less blue light than sunlight. Tungsten light appears white to

the human eye which can, up to a point, adjust to the different light sources.
However, colored objects appear different under tungsten light than they do
under sunlight because of the different spectral makeup of the two light sources.
The mixture of light wavelengths emitted by a light source is reflected selectively
by different objects, and the mixture of light reflected appears as different colors.
Some of these mixtures appear as relatively saturated colors, but most appear to us
as grays or impure hues of a color.
CIE color model
In the 1930s, the Commission Internationale de l’Eclairage (CIE) defined a
standard color space to help in the communication of color information.This
color space was based on research about the nature of color perception.The CIE
chromaticity diagram (plate 2) is a two-dimensional model of color vision.The
arc around the top of the triangle encompasses the pure or spectral colors, from
blue violet to red. Although the CIE chromaticity diagram is not perceptually
uniform—someareasof thediagram seem to compress color differences relativeto
others—it is a good tool for illustrating some interesting aspects of color vision.
By mixing two spectral colors in different proportions, we can create any of the
colors that are found on the straight line drawn between them in the diagram.
Applying this rule, notice how it is possible to create the same gray by mixing
blue-green and red light as you can by mixing yellow-green and blue-violet light.
This is possible because of a phenomenon peculiar to color vision called
metamerism .The eye does not distinguish individual wavelengths of light.
Therefore,differentcombinations of spectral light can producethe same perceived
color.
Notice how purple colors, which do not exist in the spectrum of pure light, are
found at the bottom of the diagram. Purples are mixtures of red and blue light—
the opposite ends of the spectrum.
