Density Balance Adjustment (Adjustment Flow When Changing the Screen)
Perform the density balance adjustment in the adjustment flow when changing the screen.
The density balance adjustment is required when the selection of screen and gamma automatic adjustment do not improve print results or when you want to perform the high accuracy adjustment.
The density balance adjustment measures the output chart using a spectrophotometer, and automatically correct the density balance according to the feedback of the measurement result.
Position of the Density Balance in the Adjustment Flow When Changing the Screen
The density balance adjustment is required when the selection of screen and gamma automatic adjustment do not improve print results.
In the pre-output image quality adjustment flow, this adjustment is positioned shown below.

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.
If the winding motor is stopped, refer to Prepare the Machine.
Cut out a printed test chart from the media core of Roll Winder RW-201.
When cut out the printed chart, refer to Cutting the output paper and be careful not to injure your hands or fingers.
The subsequent operations are described for the case where the spectrophotometer i1-Pro/i1-Pro2/i1 iSis XL is used.
If you use FD-5BT/FD-9, refer to the user's guide of the selected colorimeter.
On the computer where the ProfileMaker Measure tool has been installed, select [Start] - [All Programs] - [X-Rite] - [ProfileMaker Pro 5.0.10] - [MeasureTool].
ProfileMaker Measure tool starts.
The following description uses screen examples in English. To change the display language for the menu and messages, select the language from [Language] - [English] on the Measure Tool toolbar, and then restart the ProfileMaker Measure tool.
When the following message is displayed, click [OK].
