Overview
The Tools Mode enables you to establish the default settings for
your digital press, with or without a scanner, to fit your individual
requirements. You can change the settings for a variety of
features, such as the initial screen to display when the press is
powered on, the language to display on the Touch Screen, special
paper sizes that can be used in certain Paper Trays, timers, audio
tone controls, default settings for scanner features, image quality
settings, and more.
Entering and exiting Tools Mode
Key points:
• If you attempt to access the Tools Mode while a job is printing,
access to the screens will be delayed until the job completes
printing.

Auto Color Calibration
Key point 1: The digital press Color Calibration procedure does
not affect the quality of print jobs sent through your color server. It
is for scan to print jobs only.
The digital press has a number of monitoring sensors, as well as
feedback and control mechanisms, that are designed to enhance
overall calibration stability. Image quality is also automatically
adjusted periodically during operation to keep the calibration as
close as possible to the initial setup conditions.
The color server connected to your digital press also has
calibration procedures that you can use for network jobs.
Key point 2: Calibration targets can be printed only on A4 or letter
sized paper. Ensure that your digital press has A4 or Letter paper
loaded in one of the paper trays.
Key point 3: You should be skilled in color science and calibration
procedures before attempting to use the options available on
these screens.
What to know about screening
The digital press with scanner uses an advanced proprietary
screening technology to produce the colors, pictures, tints, and
shades required to produce high-quality prints.
PG is an abbreviation for Pattern Generator. The R in 200R refers
to Rotated Line screen, and the C in 200C and 15C refers to
Cluster Dot screen.

DocuColor 5252 System Administration Guide 2-15
Tools Mode
2 Tools Mode
The five screening methods and what you should remember about
each are described in the following table.
The color server uses information from the PostScript job and the
software print driver to determine which screen is used for a
particular job.
Screening
Method What to Remember
150C (LPI
Cluster Dot)
Provides better coverage on rough paper
Larger dot provides better color stability
Reduces black and other solid color mottle
Provides better black coverage due to black toner
granularity
Dot size is better for impressions containing tints,
highlights, and pastels
Most suitable for pages requirement careful control
of highlights
Poorest performance on text
200C (LPI
Cluster Dot)
Produces fine rosettes that can better emulate
offset lithography.
May leave jaggies on text (fonts)
Better for creating smooth gradients with minimum
contouring
Best for graphics and images
Switch to the 200R screen if banding occurs
200R (LPI
Rotated Line
screen)
The angle is fixed and cannot be adjusted
Has vertical screening for black, which is better for
text and line art.
Switch to the 200C screen if banding occurs.
Best all-purpose screen.
300 LPI Line
screen
Generally considered a special use screen.
Better edges on colored text with fewer jaggies.
Poor color stability due to small size of dot.
The entire color gamut must be reproduced in two-
micron area.
600 LPI Line
screen
Least color stability due to small size of dot.
Not recommended for most workflows.
Used primarily for testing.

To access the calibration procedures:
1Touch the Auto Color Calibration button from the Machine
Defaults 1 screen. The Auto Color Calibration screen appears.
2From this screen, you can perform the following tasks:
• Run Calibration
• Check Gradation
• Manual Adjust
Key point: Touch the Reset button on the Auto Color Calibration
screen to return any settings you changed to their last saved
values. Once you exit Tools Mode, any changes you have made
are set.
Refer to the following procedures for detailed information
regarding each option displayed on this screen.

Run Calibration
Use the Run Calibration feature if it is visually obvious that the
gray balance on your scan to print jobs is not correct. During the
Run Calibration procedure, the digital press creates a Look Up
Table by reading the 12 Toner Density Patches that print out. The
digital press then compares those readings to the factory-set
target values and makes the necessary adjustments to bring the
values within the target range.
Note: PG is an abbreviation for Pattern Generator. The R in
200R indicates Rotated Line screen, and the C in 200C and 150C
indicates Cluster Dot screen.
1Touch the Run Calibration button on the Auto Color Calibration
screen to begin the calibration process. The Run Calibration
screen appears.

2Do one of the following:
• Touch the 300 PG button to calibrate the 300 Line screens
(200R, 200C, and 150C screens). Use this option only if you
have noticed a problem with halftone screening.
• Touch the 600 PG button to calibrate the 600 Line screen. Use
this option only if you have noticed a problem with the gray
scale on text.
• Touch the 300 PG & 600 PG button to calibrate all the
screens.
3Press the Start button on the Control Panel. The calibration
process starts and color patch prints are printed.

2 Tools Mode
Check Gradation
The Check Gradation feature allows you to print gradated color
patch prints for each line screen on the digital press. These
gradated color patch prints are used to verify that the dry ink/toner
densities for CMYK and Grey balance are correct. If you are
dissatisfied with the appearance of any color on the print, you can
manually adjust the dry ink/toner densities for Cyan, Magenta,
Yellow, and Black using the Manual Adjust feature. It is
recommended that you begin your calibration by calibrating the
300 PG screen first. This is the basic line screen that is used, and
all other line screens are calibrated against the 300 PG screen.
Use this feature daily and compare the output of gradated color
patches to the color patch prints from the previous day. Under
normal operating conditions, there should be no difference
between them. Automatic sensors and control mechanisms in the
digital press with scanner should maintain consistent calibration.
If there is an obvious visual difference between two days’ color
patches, run the calibration process on the color server, then run
this gradation process again.

the gradation.
