Overview
2.About color printing
Traditional offset printing requires time, people, materials, and
many steps to produce quality color output. Digital technology is
changing the way the printing industry works. All the steps that
used to be performed for offset printing have now been digitized
and can be performed on your computer. The digital color press
makes it possible for you to print fast, offset-quality images.
The flexibility and control offered by digital technologies and
software applications can give you excellent results.
Understanding the variables that affect the output image quality.
These variables include: the quality of the original that is scanned
into a computer, resolution, color management, imaging
technology and a variety of other factors, are some of the things
you need to understand to maximize your results.

About color printing
Image quality
Quality starts with the original
When creating a document with color images, you first need to
understand the capabilities, strengths, and weaknesses of the
software you are using. This applies to both the PC and Mac
platforms of software such as QuarkXPress
FrameMaker
Adobe Photoshop
®
, Adobe Illustrator®, Macromedia FreeHand®, and
®
, to mention just a few of the applications

available today. Having a thorough knowledge of these programs
will assist you in creating your files correctly.
The following sections describe the different variables that affect
the output image quality. These variables include: the quality of
the original, resolution, color management, and a variety of other
factors.
Whether your original image is a scanned transparency, a
photograph, or a digital file, the image characteristics you start
with will have a major impact on the end results. As an image goes
through the production process, it is displayed in many different
ways: as digital information in the scanned image file; as pixels of
red, green, and blue (RGB) light on the computer screen; and as
dots of cyan, magenta, yellow, and black (CMYK) dry ink/toner on
paper. During each step of the process, the colors of the original
are transformed to meet the needs of these different technologies
and the output media.
2-2
DocuColor 5252 Operator Manual
How input determines output
Successful reproduction of color images depends on a number of
factors, starting with the differences in how the various
technologies that affect the image translate and display the color.
ScannersScanners are able to capture colors only as red, green, and blue
(RGB). Two types of scanners are used today: drum and flatbed
scanners. A flatbed scanner does not have as much color range
as a drum scanner.
•A drum scanner uses a photomultiplier tube (PMT) that is very
sensitive and accurate. The original document is attached to
the drum which is rotated past a group of sensors - one each
for red, green, and blue, and a fourth that sharpens the digital
image. An internal computer usually performs the RGB to
CMYK (cyan, magenta, yellow, black) conversion.
•Flatbed scanners use a less expensive and less accurate
charge coupled device (CCD) sensor. The original is placed on
a flat glass surface and the array of CCD sensors passes by
the original, and collects the red, green, and blue data. RGB to
CMYK conversion is usually performed on a computer
workstation.

About color printing
Image key
Some scanners, especially low-end desktop models, tend to
compress the tonal range of an image and increase the contrast or
difference between light and dark areas. If the contrast of your
original is too high or too low, detail could be lost when it is
reproduced. Images that have few dark areas or shadow tones
are called high key. In contrast, a low key image consists of large
areas of shadow and darker midtones (the tones that fall in
between).
Some scanners allow you to manually override automatic
exposure controls in those cases in which the images have these
characteristics.
Imaging software applications use histograms or graphic displays
to show the distribution of pixels inside the different tonal ranges
of an image.

Grain/image size
The size of an original scanned image is also important to the
clarity of the output image. If an image is enlarged too much, the
grain of the image may become obvious, detracting from the
image quality. In digital photographs, the grain introduced by
scanning limits how large an image can be successfully enlarged.
The guidelines below show the maximum recommended
enlargement for a few standard sizes.

Our eyes are sensitive enough to perceive thousands of different
colors in the spectrum of visual light, including many colors that
cannot be displayed on a color monitor. The color range, or color
gamut, that can be printed with dry ink/toner is even more limited.
Understanding the color gamut is especially important when you
compare how different technologies and output devices use light
to reflect color images with what we see on a printed page. As
colors move from the scanner to the screen to the press, they are
converted from one color model to another so you do not get in
print exactly the same colors you see on the screen.
For this reason, when you are designing for printed output, you
always need to think about what can be reproduced with dry ink/
toner on paper and not what you see on your monitor.

Additive colorComputer monitors work with energized phosphors that glow red,
Subtractive colorPrinting is based on the subtractive color process. Cyan, magenta,
green, or blue on the face of a picture tube. If accurate color
reproduction is important to you, your monitor should be calibrated
on a regular basis. Calibration adjusts and corrects the gamma,
white and black points, and color balance of the monitor. Monitors
display color with impressive accuracy, but they can never match
the printed page perfectly because of the physics of color
involved. Monitors display additive color space RGB, and printing
devices use CMYK, which is subtractive color space.
and yellow dry ink/toner is placed on white reflective paper. Each
color then absorbs, or subtracts, its opposing counterpart from the
reflected white light. This process controls the amount of red,
green, and blue light that is reflected from the white paper. The
CMYK colors are printed as layers of halftone dots in various sizes
and at various angles to create the illusion of different colors. The
varying dot sizes create an effect similar to the varying intensities
of the red, green and blue phosphors of a monitor.
MediaThe paper on which the image has printed significantly affects
color reproduction. Paper reflects unabsorbed light back to the
eye of the viewer. Therefore, the more reflective the surface of the
paper, the wider the range of colors that can be produced.
Refer to the Color Materials Usage Guide included in your
Customer Documentation package for more information on how
paper influences image quality.
Color serversOnce a file is ready to print, it is sent to a color server to be
processed for output. Color servers typically offer a wide range of
functionality, including electronic collation, processing while
printing, color management, automatic trapping, and calibration.

A color gamut is a range of colors. The gamut that the human eye
can see is much larger than can be produced in a photograph.
The photograph gamut is much larger than that of an RGB

Color models
Video technology (computer monitors, scanners, and television
screens) sees color as transparent light and uses an RGB model
to display colors. To display color appropriately on video
technology, captured images are broken down into pixels (picture
elements) that are projected as rays of red, green, and blue light.
Printers see color as reflective light, which reacts much differently
on hard copy printed images and bounces off nontransparent
surfaces. Colors are translated into combinations of cyan,
magenta, yellow, and black, using a CMYK color model, to get true
colors.

There are limitations to achieving the exact colors when
converting from RGB (for video display) to CMY (for
print). For example, CMY pigments aren’t capable of
producing consistent black or gray tones.
In cases in which the three ink or toner colors overlap
heavily, software applications automatically vary the
percentages of cyan, magenta, and yellow to enhance
image quality and improve printability. This technique is
known as undercolor removal, or UCR, in which black ink
is used to replace cyan, magenta, and yellow ink in
neutral areas only (that is, areas with equal amounts of
cyan, magenta, and yellow). This uses less ink and
provides greater depth in shadows. UCR is generally
used for newsprint and uncoated stock
Another form of undercolor removal is called Gray
Component Replacement (GCR). To compensate for the
neutral or grey tones created during the conversion of
RGB to CMYK, black ink replaces portions of cyan,
magenta, and yellow ink in colored areas, as well as in
neutral areas. GCR separations tend to reproduce dark,
saturated colors somewhat better than UCR separations
do, and they maintain gray balance better in print.

Color management
Since the color on a screen differs from the color produced by the
press, it is necessary to have a Color Management System
(CMS). The CMS identifies and bridges the gap between the RGB
and CMYK color spaces belonging to your monitor, press, and
scanner. Mac and Mac OS compatible computers use the Apple
ColorSync CMS to implement and handle the profiles of these
devices. For Windows - based PCs, refer to your PC Operator
Manual for the compatible CMS.
Without a color management system, one image will appear
different when reproduced on different devices due to
inconsistencies in color gamuts.
A color management system helps you obtain more consistent
results by aligning the color gamuts used by different devices.

Halftone dots
Halftone dot shapes
About color printing
Halftone dots are combinations of spots that create a printed dot.
The dots shown here demonstrate different print resolutions. The
illustration on the left contains 25 possible printer dot cells, which
can create different gray values. The illustration on the right
contains 256 printer dot cells, which allows for a greater range of
grays. To print a visually convincing halftone image, you need at
least 150 shades of gray.
Because toner reacts differently with different paper surfaces, the
characteristics of your paper generally determine the screen ruling
you should use (for example, dry ink/toner tends to spread on
rough, absorbent grades of paper). Different dot shapes can
enhance and improve output quality.
Solid background printing
Image quality is affected by the capabilities of your output device
and the type of paper, or media, you are using. Keep in mind the
following regarding the digital press:
•The maximum dry ink/toner coverage is 270 percent.
•The maximum color depth is 256 levels per color.
•The maximum color resolution is 600 dpi.
MediaTo obtain sharp and uniform prints, paper stocks should be
smooth and be composed of uniformly distributed fibers. Paper
formation is determined by the uniformity of paper fiber
distribution. In color printing, paper formation influences the
tendency to mottle, produce uneven spotty toner coverage, and in
solid backgrounds it determines the sharpness of the color and its
saturation.
Xerox media have been designed with evenly distributed fibers in
its structure to yield crisp and mottle-free prints.
Paper quality can vary from one side to another. Good quality
paper reduces these differences. Many suppliers use arrows on

Calibration
Calibration is essential to insuring good color quality. The purpose
of calibration is to measure how the digital press is printing the
requested colors and to then make any corrections that are
required.
Calibration at the color server should be done daily, or any time
there is the possibility that the digital press colors may have
changed from what they were in an earlier calibration. Some of the
reasons to calibrate are:
•Color displays differently on identical press models produced
by the same manufacturer.
•The temperature of machinery as it warms up affects color
intensity.
•Image quality and color reproduction on uncalibrated
equipment results in unpredictable, unreliable results.
To properly predict, manage, and minimize color variables,
hardware and software must be calibrated before production
begins.
Refer to the digital press System Administration Guide (see
page 2-12) for information on calibrating the digital press.
Refer to the manuals that came with your color server for
information on calibrating that unit.

Digital image manipulation
Although image reproduction can be a complex process, one of
the primary advantages of capturing an image digitally is that it
can be manipulated until you have achieved the desired output.
Imaging software applications are continually improving image
manipulation capabilities to simplify the process.
Sizing
When digitally enlarging an image, the pixels or cells may become
visible. The resulting staircasing, or aliasing, in diagonal lines can
be corrected using your software application to add pixels before
resizing.
Sharpening
When converting or scanning an RGB image to a CMYK image,
the image may become fuzzy. Use the sharpen option of your
software application to adjust the clarity of the image.
About color printing
2 About color printing
Color cast
Color cast is the modification of a hue by the addition of a trace of
another hue, such as yellowish green, pinkish blue, etc. This effect
can be added or removed by adding black, white, or shades of
gray points using the color balance option of your software
application.
Important additional tips
•Determine the file format.
•Calibrate equipment for the best output, if necessary.
•Include all files, fonts, and linked art.
•Determine the best way to store your data for reprint capability.
•Determine whether the data can be compressed for storage
without degrading print quality to unacceptable levels. If quality
is unacceptable after compression, consider storage methods
that do not require compression.

Output considerations
MottleNo mottle
Mottle
Mottling is uneven spotty toner coverage that occurs when printing
large, solid areas of flat color. Paper choice can be critical in
avoiding this problem. To obtain sharp and uniform images, use
only paper stock that is smooth and has uniformly distributed
fibers.
Registration
Trapping or overprinting can compensate for gaps or shifts as the
paper passes through the printing cycle.

About color printing
Trapping
Trapping compensates for misregistration by slightly overprinting
adjacent colors.
Halo
Haloes are light areas around an object that occur when printing a
darker color dry ink/toner on a lighter color dry ink/toner
background. Printing on pastel or gray paper eliminates this
problem.
Opacity
2 About color printing
Opacity is a measure of how much light can pass through paper.
When producing 2-sided output, choose a paper with high opacity
so the print from side 1 does not show through on side 2.

Overprint
Overprint allows an element to print over the top of underlying

Duplex settings
To ensure that the image orientation is correct on both sides of the
page, the correct duplex setting must be indicated in the print
driver window. If the setting is incorrect, your document could print
with the image data on one side of the page rotated 180
other side.
File formats
Computer graphics created in different graphics software
applications provide varying levels of output quality. They are
typically described in two ways: pixel-based or bitmap (bits of
information or raster files); or mathematically described objectoriented graphics (vector graphics).The most commonly used file
formats include Tagged Image File Format (TIFF) and
encapsulated PostScript (EPS).
TIFF is a pixel-based, or bitmap, format that can be read by a wide
range of applications across multiple platforms. This format is
especially useful for viewing and outputting images used with
standard office applications, such as Microsoft Word and
PowerPoint.
About color printing
o
from the
2 About color printing
EPS is an object-oriented format that provides the highest quality
images your output device is capable of printing. It is the most
reliable and comprehensive file format for desktop publishing and
graphics programs because it is device - independent.
Resolution
Resolution is the number of dots available to represent a
bitmapped image. PC monitors have a resolution of 72 dpi.
Choosing the right image capture resolution is key to getting the
most out of your image. It is important to remember that an image
can be printed only at the resolution available on your output
device. The digital press has a print capability of 600 dpi.
DocuColor 5252 Operator Manual
2-17
About color printing
Color server
Color servers are connected to your network and drive the color
output devices (digital color presses/printers). Each time an image
is sent to a printer, the color server connected to the printer
converts, or rasterizes, the data in the file into dots which can be
printed by the target output device. Each dot is assigned a specific
location, color, and density level.
Color servers optimize the color of a document by manipulating
the dots which make up the image so that it matches the gamut of
the printer.
Image quality functions typically associated with a color server
include:
•Processing while printing which allows the color server to
concurrently submit pages to the output device while
processing new images for printing.
•Advanced text and line art quality controls provide anti-aliasing
capabilities for high-quality text and graphics.
•Color Management System facilitates optimizations of images
and offset ink/toner simulations.
•Document storage keeps the rasterized file resident on the
color server for future processing.
For further information, refer to the documentation that came with
your color server.

Finishing
Folding techniques
About color printing
There are two types of finishing: the finishing that the digital press
can do and the preparation for finishing other than what the digital
press can perform.
The finishing options for the digital press are the Offset Catch Tray
(OCT), which offsets sets for easy separation, or the High
Capacity Stacker (HCS), which collates and offsets stacks
received from the press.
To prepare output for finishing other than what the digital press
can perform, you must first understand the various folding
techniques, binding methods, and finishing touches available. You
must also have software such as DK&A, Ultimate Technographics,
Scenicsoft, Press Wise, etc. to enable you to correctly prepare the
document for printing.
Parallel fold
A parallel fold means that the paper is folded parallel to either the
long edge or short edge of the paper.
Right angle fold
The Right Angle Fold is a fold that falls at a right angle to the
previous fold. A right edge fold takes the parallel fold one step
further.
Accordion fold
An Accordion fold is two or more parallel folds in opposite
directions.
Gate fold
Gate Folds create a pair of foldouts that can be imaged upon.
They are especially useful for brochures and book covers.

Binding preparation
Nested signature and binders creep
The effects of binders creep are most obvious when thick paper is
folded or multiple signatures are nested with each other. After
trimming, the innermost signatures will have a smaller page size
than the outermost.
Gathered signature
Gathered signatures are folded, placed on top of one another, and
bound together. This process minimizes the effects of binders
creep.
Bottling
Bottling occurs when signatures are not folded at precise right
angles.
2-20
DocuColor 5252 Operator Manual
Binding methods
Saddle stitching
Perfect binding
Mechanical binding
About color printing
Saddle Stitching is accomplished using a stapler or a high-speed
binding machine that inserts and bends thin wire through the spine
of a document. This wire leaves the document looking like it has
been stapled. The maximum number of sheets that can be saddle
stitched is 32.
Providing an unprinted area on the inside cover of a perfect bound
book gives an area for the glue to adhere to and allows it to wrap
around some of the inside pages.
Mechanical binding allows pages to be flat, so it is often used for
technical manuals, notebooks, and calendars.
Looseleaf Binding
Looseleaf bindings are ideal for documents that undergo frequent
updates because pages can be inserted and removed easily.

Final finishing touches
Die cutting
In die cutting, shapes are cut out of a page with sharp knives. It is
most often used to create attention-getting documents, or for
packaging with unique shapes, like video box covers.
Lamination
Laminated documents are encased in a thin, washable plastic
coating to protect frequently handled documents from the
elements and human wear and tear.
Varnish
Varnishing protects documents from the elements and can also be
used as a design to enhance a document. Depending on the
desired effect, gloss or matte (dull) varnish can be applied to an
entire document (flood coverage) to give it a smooth overall finish,
or to specific portions of a page (spot coverage) to highlight some
parts of the document while de emphasizing others.
Embossing
When a document is embossed, it is pressed between two dies (or
molds) to create a raised or lowered texture on the sheet. This
works best on uncoated cover weight papers.

you reach the files that can be downloaded.
Paper Handling
For the best performance load paper with the seam side down in
Trays 1 and 2 and seam side up in Tray 3. The seam side is where
the ream of paper is sealed.
. Use the search
Note: Many suppliers use arrows on the product labels to
indicate the preferred side to image first. Use this side (as
signaled by the arrow) as equivalent to the seam side when
loading the paper.
Many factors affect the performance of paper, including room
temperature, humidity, paper quality, dust, and the size of the
image area. If jams or paper curl problems occur, remove the
paper from the paper tray, turn it over, place it back in the paper
tray, and resume printing. If the problem is rectified, continue to
load your paper in the same manner. If the problem is not rectified,
load a new ream of paper and try the process again. If the problem
persists, your System Administrator can go into the Tools Mode
and try the different decurler settings. If, after trying all the
previous suggestions, the problem still persists, call your Xerox
representative.

Store Paper:•On a flat surface. Do not store paper directly on the floor, since
For reliable digital press operation and good print quality, Xerox
recommends the following:
that increases the possibility of moisture absorption. Paper
should be stored on pallets, or shelves or in cabinets in an
area protected from extremes of temperature and humidity.
•In a low dust area.
•In a low humidity area. Humidity is one of the most important
steps to promote proper paper characteristics. Optimum paper
storage conditions include a relative humidity of 35% to 55%.
An increase in humidity can cause paper to develop wavy
edges. This occurs because the edges absorb moisture while
the rest of the ream remains unaffected. Wavy edges can
cause jams and misfeeds.
•In an air-tight moisture proof container.
•In controlled temperature. The temperature in the room where
paper is stored can have a significant effect on how that paper
performs in the machine. Optimum paper storage temperature
o
is 68
to 76o F (20o to 24.4o C).
Cutting and Trimming
Paper
For additional paper handling information, refer to the Color
Materials Usage Guide.
Proper cutting of the paper is important. Mills offering paper in cut
sizes cut their papers using state-of-the-art rotary slitters on high
performance systems. Slitting and edge trimming by circular
knives with dust removal at every cutting point prevents
contamination of the paper.
Trimming papers from parent sheets to get the desired output size
may generate dust if dull knives are used. The recommendation is
to delay trimming until printing has been finalized to prevent paper
dust generation and contamination.
If preprinting is imperative, an in-house maintenance program,
including knife sharpness maintenance and dust removal with a
vacuum or air system, are key to achieving good results.

Paper Guidelines
Paper and Paper Trays
For the best results, remember the following:
•Do not load paper or other materials above the MAX line.
•Do not use wrinkled, torn, curled, or folded paper.
•Use the recommended paper sizes and weights.
•Do not mix sizes or weights of paper in a paper tray.
•Ensure that the tray indicator LEDs are set for the correct
weight range.
•Follow the Recommended Materials List suggestions found at:
www.xerox.com
Copy paper is fed into the digital press in one of two positions.
One position is called long edge feed (LEF). Long edge refers to
the long edge of your copy paper. When you see LEF, position
your copy paper so the long edge is fed first. The other position is
called short edge feed (SEF). Short edge refers to the short edge
of your copy paper. When you see SEF, position your copy paper
so the short edge is fed first.
Note: It is imperative that you load paper with the paper guides
adjusted properly. If the paper is NOT loaded properly, it will skew
and jams will occur.

When the paper is exposed to heat, the paper loses moisture and
curls toward the heat source. High coverage jobs tend to curl more
due to the toner plastification effect on the paper surface. The
system tries to reduce this by using mechanical devices within the
paper path called decurlers.
Your system has been designed with an automatic curl control
system that uses information such as: the amount of coverage on
the page, paper weight, whether the paper is coated or uncoated,
and the current humidity and temperature to determine the
amount of pressure needed at the different decurlers to reduce
output curl.

Duplexing
If you are experiencing excessive curl, remove the paper from the
tray, turn it over and replace it in the tray. If the curl is still
excessive, refer to the System Administration Guide, Tools Mode
chapter (see page 2-66), to change the decurler settings to
accommodate the environmental and paper conditions.

occur.
Tabbed Inserts can be loaded into Tray 3 as nonstandard paper.
•When loading, the nontabbed, short edge of the tabbed insert
should be the lead edge to the digital press.
•If a jam occurs while running tabbed sets, there is no recovery
procedure.
•You have to manually reassemble your originals and
prints, determine where the job left off, and resume printing
or cancel the job and start again.
•The size of the tabbed insert should be 9 x 11 inch (229 x 279
mm) for letter size tabs (223.5 x 296 mm for A4 equivalent
tabs).
•The proper weight of the insert should be selected on the
tray.
•Select Non-standard size and input 11 inches or 296 mm for
A4 as the X axis and 9 inches or 223.5 mm for A4 as the Y
axis dimensions for SEF.
