Basic system configuration
The basic system configuration contains the following parts.
■Printer
■Controller
■Scanner.
The basic system configuration has one of the following controllers
■Fiery ® PRO80/S450 65C-KM Color Server (IC303/IC305), default including a
photo spectrometer
■Creo controller, IC304/IC304 Plus, default including a photo spectrometer
■Fiery ® X3e TY2 65C-KM (embedded controller (IC408) for which a photo spectrom-
eter is optional.
■Océ PRISMAsync controller (Océ CS655 and Océ CS665 only) for which a photo
spectrometer is optional.
You can only calibrate a controller if you have a photo spectrometer.
Note:
Do not use the ColorCal / Off-the-glass method as described in the controller documen-
tation.
Chapter 1 - Introduction6
Basic system configuration

Why calibration
The printer is calibrated for a screen at installation and at every next service visit. The
default screen is Dot 1. The Océ CS550/CS6xx Pro will hold on to the calibrated level
of print quality by automatically performed adjustments. In normal circumstances there
is no need to do additional calibrations.
External circumstances, for example temperature, humidity and consumables change over
time. These changes effect the colour reproduction. You can perform a calibration as de-
scribed in this document to eliminate the effect of the external circumstance on the colour
reproduction.
There is no need or use to calibrate the scanner.

Why calibration

Main steps in calibration

Sub-stepMain step
‘2.0 Check the print quality’ on page 101. Check the print quality
Continue only if the colour reference chart does not meet your requirements.
‘3.1 Calibrate the EFI controller’ on page 12
or
‘3.1 Calibrate the Creo controller’ on page 17
or

2. Calibrate the controller
‘3.2 Check the print quality’ on page 28
The result of the controller calibration as checked in 3.2 normally meets the required
print quality. If the print quality still does not meet your requirements, you can
consider to proceed with the printer calibration.

Note:
1 Calibration of your copy process only requires step 4.1 and 4.2.
Note:
2 Calibration of the printer requires calibration of the controller because the controller
takes the printer settings into account at controller calibration.

2.0 Check the print quality
Introduction
You can print the Océ Color Reference chart to check the print quality. You can download
the print files used in this document form the Océ website. Before you print this chart,
you need to warm up the machine.
Before you begin
Load the A4/Letter portrait reference media with the correct paper settings.
Load the A3/Tabloid reference media with the correct paper settings.
Note:
Reference media is the media that you use mostly (bulk). The Océ reference media is
Océ Top Color 90 g/m2.
Warm up the printer
1. Print the file 'Océ Startup Page.pdf'.
Result
The Océ CS550/CS6xx Pro is warmed up and ready to evaluate the print quality.
Print the Océ Color Reference chart
1. Print the file 'Océ Color Reference Chart.pdf'.
Result
The result is a printed Océ Color Reference chart to evaluate the print quality.

3.1 Calibrate the EFI controller
Introduction
The external controller is either an EFI (IC303/IC305/IC408), a Creo (IC304/IC304Plus)
or an Océ PRISMAsync controller. This procedure describes the calibration of the EFI
controller. In case of an IC408 controller you must use CWS on a remote PC. Before
you can calibrate the EFI controller you must print the calibration chart.
Print the calibration chart
1. From 'Command Workstation', click 'Server' - 'Manage color...'.
2. Click 'Calibrator'.
[1] Calibrator button
3. Select or check the measurement method.
[2] Measurement method selection list

3.1 Calibrate the EFI controller

4. Select the media you want to use for calibration.
[3] Media selection list
5. Click 'Print...' to set the print options and print the sorted patches chart.
[4] Print options button
6. Select the following settings.
■At 'Page Type', select '34 Sorted patches' for A3/Tabloid (recommended).
Select '21 Sorted Patches' for A4/Letter.
■At 'Paper Size', select the setting according to the previous step.
■At 'Input tray', select the tray that contains the selected paper type and size.
■At 'Number of copies', select 5.
Use the last print to calibrate.
■At 'Show Advanced Options', check at 'Halftone' the correct screening. The default
is 'Dot1'.
