Density Balance Adjustment (Adjustment Flow When Changing the Screen)
This measures the output chart using a spectrophotometer, and automatically correct the density balance according to the feedback of the measurement result.
Perform the following three processes in the order indicated:
STEP 1: Measure the density balance using a spectrophotometer.
STEP 2: Save the measured data of the density balance.
STEP 3: Register the adjusted value of the density balance in the machine.
• 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.

Measuring the density balance using a spectrophotometer
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.
ProfileMaker 5 v5.0.10
https://xritephoto.com/ph_product_overview.aspx?ID=757&Action=Support&SoftwareID=931To use the spectrophotometer, i1iSis, perform Step 10 (select [Measure] from the menu) followed by the procedure of "• For the spectrophotometer, i1iSis."
To use FD-5 BT or FD-9, use FD-S2w. For details on operations, refer to the user's guide supplied with FD-S2w. When FD-9 is used as the spectrophotometer, test charts with QR code are printed out. Measuring test charts with QR code allows you to select a definition chart on FD-S2w and automatically input chart numbers and printer information to the machine, thereby, helping ensure efficient input work.
On the control panel of the main body, press Utility/Counter.
The [UTILITY] screen is displayed.
Press [Administrator Setting] - [System Setting] - [Expert Adjustment] - [Quality Adjustment] - [Density Balance Adjustment] in sequence.
Press [Density Balance Chart Output].
Select the chart to be output according to the spectrophotometer to be used.
After the selection, press [Print Mode].
The recommended charts are as follows.

When spectrophotometer-1 (FD-9) is used for measurement, test charts with QR code can be printed out for both [Type 1] and [Type 2]. Measuring test charts with QR code allows you to automatically input information such as chart numbers to the machine.
Set the paper on the [PRINT MODE] screen and press Start on the control panel.
The color chart is output for measurement using the spectrophotometer.
To use FD-5 BT or FD-9, use FD-S2w. For details on operations, refer to the user's guide supplied with FD-S2w.
