About G7 Calibration

In addition to the regular controller calibration, measure the accuracy and check the Gray Step (gray balance)

measurement result

as necessary. Based on the values for gray color standard state, execute the advanced

controller calibration (G7) as necessary.

The following two methods are available to perform G7 Calibration.

-

Manual adjustment by using Color Centro

-

Automatic adjustment by using the

touch panel

.

Meaning and Purpose of Advanced Controller Calibration

While the regular controller calibration adjusts the output density of C, M, Y, and K colors, the advanced con-

troller calibration uses primary colors (C, M, Y, and K) as a one-dimensional curve and adjusts gray balance

for enhanced color reproduction accuracy.

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.

.

When to perform

-

Any time (If the accuracy measurement result presented a greater ΔCh value (saturation difference), etc.

than the preferred value)

.

Precautions

-

To reproduce stable colors, make other image quality adjustments as necessary, such as when chang-

ing screens or papers or when hue is important. For details, refer to page 3-3, page 3-4, and page 3-6.

-

If the advanced controller calibration (G7), page 3-3, page 3-4, or page 3-6 does not improve color sta-

bility, creating a profile may resolve the problem.

.

Intended Environment

* The sample screen may be different from the actual display depending on your system environment and

application version/revision.
