Color Density Control (Adjustment Flow When Changing the Screen / Regular Adjustment Flow (Standard) / Regular Adjustment Flow (High Accuracy))
You can execute the color density control only when the RU option (Relay Unit RU-509) is available.
You can use the density sensor equipped with the RU option (Relay Unit RU-509) to measure the patch density of the chart for γ correction and perform calibration.
Instead of the γ correction by the internal IDC sensor, the density is corrected by using the printed chart image. This enables secondary transfer, fusing, and correction with each paper's characteristics taken into consideration.
With the RU option, manual calibration is unnecessary. Note that in that case, on the touch panel of the main body, press [Adjustment] - [Quality Adjustment] - [Color Density Control] - [Basic Setting], and then set [Periodical Adj. Execution] to [ON]. [Color Density Control] is not selectable unless [Use Color Density Control] is set to [ON].
The color density control consists of the following three adjustments:
Details of color density control | Description |
|---|---|
Basic Setting | You can enables the color density control and set the execution timing, etc.
|
Each Paper Type Color Sensor Adjustment | You can measure and register the density adjustment data corresponding to each paper type.
|
Color Density Manual Control | You can manually adjust the color density. |
• Image quality adjustment flow and the position of this adjustment
In the pre-output image quality adjustment flow, this adjustment is positioned shown below.
Perform the previous adjustment before proceeding with this adjustment.
When Integrated Color Care Unit IQ-501 is mounted on the machine, this adjustment is positioned in the same way as the above.
To not continuously perform the series of adjustment of the image quality adjustment flow, perform Gamma Automatic Adjustment (Adjustment Flow When Changing the Screen / Regular Adjustment Flow (High Accuracy)), and then resume from the next adjustment.

[Switch Color(1st or 2nd)]
[Precise]
[Adjustment Interval]
[OFF]
To automatically perform the density control with the RU option (Relay Unit RU-509), set the [Periodical Adj. Execution] to [ON].
Each Paper Type Color Sensor Adjustment
You can measure and register the density adjustment data corresponding to each paper type.
* Perform optionally this adjustment as needed.
* When Integrated Color Care Unit IQ-501 is mounted on the machine, adjustment is made automatically. When Integrated Color Care Unit IQ-501 is not mounted on this machine, chart color measurement is required in the external spectrophotometer (i1-Pro, i1-Pro2 and i1-iSisXL, or FD-5 BT and FD-9).
Also, the dedicated application is required to measure test charts. The application varies depending on your spectrophotometer. For i1-Pro/i1-Pro2 and i1-iSisXL, use X-rite Measure Tool. For FD-5 BT and FD-9, use FD-S2w. Install the tool in advance.
You can download X-rite Measure Tool free of charge at the following Web site. After installing the tool, restart the computer.
