Advanced Controller Calibration (Regular Adjustment Flow (High Accuracy/Adjustment Flow When Changing the Screen))
Advanced calibration provides a method to easily correct color tones, without the need to create a new profile as was necessary in previous machines, and without having to adjust the density of primary colors (CMYK).
It is recommended to perform the advanced controller calibration (Exact Color or G7 calibration) once every three months.
There are two methods for advanced calibration:
Exact Color
When you want to improve the accuracy of a standard profile, correct the profile.
It corrects reproduction of mixed colors of CMYK as well as that of each color of CMYK.
It can achieve higher accuracy than regular calibration can.
Perform this adjustment when you want to eliminate the gap between machines if you have more than one of this machine.
G7 calibration
It is designed to acquire gray reproduction in various printing methods by adjusting the curve of each color of CMYK.
Exact Color is the default setting in Color Centro. When Color Centro is set to Exact Color, G7 calibration cannot be added and used side-by-side. When you want to change Exact Color to G7 calibration, contact your service representative.
You do not need to perform the advanced controller calibration (Exact Color or G7 calibration) in the regular adjustment flow (high accuracy) every time. It is recommended to perform the calibration procedure once every three months.
Note for Exact Color
If the Exact Color function does not improves color stability, creating a profile may resolve the problem.
Notes when you switch to G7 Calibration:
You cannot use profiles and conversion tables (LUT) that you created by using Exact Color.
The following profiles and tables are not automatically deleted from the image controller.
To delete them, delete them manually.Customized profiles that are registered before switching
Conversion tables that are registered before switching (LUT)
If you are using G7 calibration in an environment other than Color Centro, you can continue to use the following data.
Profiles of user data
Spot color tables of user data
For hold jobs that you saved before you switch, specify profiles appropriately, and then perform RIP (color conversion) again. After you switch, check hold jobs.
