Features of Color Calibration Using the Spectrophotometer Unit
Color calibration improves color consistency by compensating for slight differences in how color appears when printing
due to individual variations or aging among the printers.
Executing color calibration from the Spectrophotometer Unit prints a test pattern (built into the printer), which will be
measured automatically by the Spectrophotometer Sensor on the Spectrophotometer Unit.
The printer is then configured with calibration adjustment values reflecting the results of color measurement.
By using the Spectrophotometer Unit, you can execute color calibration with higher precision compared to using the
printer sensor.
Important
•
In order to increase the color stability precision when executing color calibration, maintain a constant temperature and humid-
ity environment each time within the range of temperatures of 15 to 30°C and within the range of humidities of 40 to 60%.
Executing color calibration under various temperature and humidity conditions may prevent the printer from making the cor-
rect adjustments.
•
Before color calibration, ensure the printer is not exposed to direct sunlight or other strong sources of light.
If the printer is exposed to strong sources of light, correct adjustment may not be possible.
Recommend Timing for Color Calibration
We recommend color calibration in the following situations.
•
After initial printer installation
•
After Printhead replacement
•
If colors seem different from before, despite using the same printing environment, under the same conditions
•
To ensure uniform colors when printing on multiple printers (however, be sure to use the same version of firmware
and printer driver, under the same settings)
•
When the Execution Guide is displayed (Specifying Execution Guide
•
The results of a Color Check exceed the threshold value.
(See "Color Checks Using the Spectrophotometer Unit (option).")
Executing Color Calibration from the Control Panel on the Printer
Execute color calibration from the Control Panel on the printer as follows.
Refer to the information on Color Calibration Management Console operations when executing color calibration from
the computer.
(See "Executing Color Calibration (Windows).")
(See "Executing Color Calibration (Mac OS X).")
•
Preparing the Printer
1
You can confirm whether the paper to be loaded can be used in color calibration.
(See "Paper that can be used in Color Calibration.")
2
Load the paper.
(See "Loading Rolls on the Roll Holder.")
(See "Loading Rolls in the Printer.")
Note
•
If Adj. Quality has not been executed even once on the paper you are using, execute Adj. Quality in the Control
Panel menu.
(See "Automatic Banding Adjustment.")
