 Calibration principle
Measuring a color chart print result (ink discharge amount) in a calibrator.Created Color ID information based on
the obtained color difference values (L*, a*, b*) is stored on the printer.When printing, the printer driver takes the
Color ID to correct the number of ink droplets (dot generation rate) for each of different sized droplets of each
colors.
 Correlation with Head ID adjustment
Head ID: In the print head manufacturing process, ink discharge amount of each head is actually measured to get
individual characteristic information. The information is the Head ID that was set to revise a characteristic
difference between the heads. The Head ID is shown with a label on the each print head, therefore you must input
the Head ID to the printer after print head exchange.
 Before performing Colorimetric Calibration, the conventional Head ID must be pre-
registered.
 If you do not perform Colorimetric Calibration after performing Head ID adjustment,
the printer will be controlled only by the Head ID. In that case, the color precision is not
guaranteed.
 Flow of the Colorimetric Calibration
The following steps show the Colorimetric Calibration:
1. Print a nozzle check pattern. If there is nozzle missing, run a head cleaning.
2. Print a color chart with the printer which you want to calibrate via ColorBase2.
3. Scan the printed color chart with a calibrator.
4. ColorBase2 calculates a Color ID from the scanning result and calculation parameter of the colorimetric
calibration.
5. Write the Color ID to the printer. When printing, printer driver refers to the data of the User Color ID area.
