Select

Allows you to select, for the registration of Exact Color adjustment table, whether to register Exact Color adjustment data or to register data from your selected accuracy improvement session.

List

Displays the results for calibration accuracy measurement, Exact Color adjustment accuracy measurement, and Exact Color adjustment accuracy improvement check.

C, M, Y, K

Allows you to select the curve to be displayed. Check to display curve. Remove check to not display curve.

Measure D-Max

Displays measured D-Max when calibration is executed or calibration accuracy is measured.

D-Max is the maximum density.

If the measured value is too much lower than D-Max, the color of high density may not be reproduced well.

It is the state in which the density is not enough.

If the measured value too much higher than D-Max, the gradation may become rough.

It is the state in which the output from 0% - 100% is performed with a smaller number of steps (example: 0% to 80%).

Target

Displays the target curve for the paper recommended for the selected paper type when this item is checked.

Density(before Calibration)

Switches between whether or not to display the graph from before the calibration.

Density(after Calibration)

Switches between whether or not to display the graph from after the calibration.

CMYK Density graph

Displays the following measurement curves:

• Target curves of paper that is recommended for the paper type

• Data before calibration

• Data after calibration

Gray Step - ΔE Ave.

Displays the average ΔE value for gray steps of the Exact Color target. ΔE (Delta E) denotes color difference.

It represents the distance between any two points in the Lab color space.

The value of ΔE represents difference between colors.

Gray Step - ΔE Max.

Displays the maximum ΔE value for gray steps of the Exact Color target. ΔE (Delta E) denotes color difference.

It represents the distance between any two points in the Lab color space.

The value of ΔE represents difference between colors.

Gray Step graph

Displays the gray balance of the gray step.

Δa* (delta a star) means difference of a* from the target in a color space.
a* means the color shade in the direction of red to green in a color gamut.
It represents that, the larger a* is, the stronger red is, and the smaller a* is, the stronger green is.

Δb* (delta b star) means difference of b* from the target in a color space.
b* means the color shade in the direction of yellow to blue in a color gamut.
It represents that, the larger b* is, the stronger yellow is, and the smaller b* is, the stronger blue is.

Close

Closes the screen.

Iteration

Displays the order that you measured charts.

Date and Hour

Displays the date/time when the measurement was taken.

3. Exact Color - ΔE Ave.

Displays th average ΔE value for the Exact Color target. ΔE (Delta E) denotes color difference.

It represents the distance between any two points in the Lab color space.

The value of ΔE represents difference between colors.

3. Exact Color - ΔE Max.

Displays the maximum ΔE value for the Exact Color target. ΔE (Delta E) denotes color difference.

It represents the distance between any two points in the Lab color space.

The value of ΔE represents difference between colors.

Gray Balance

Displays a color reproduction result with the gray CMY ratio that is defined by G7, and wΔCh which is difference of saturation from the target color.

Gray Balance graph

Displays the measurement result of Gray Balance.

Δa* (delta a star) means difference of a* from the target in a color space.

a* means the color shade in the direction of red to green in a color gamut.

It represents that, the larger a* is, the stronger red is, and the smaller a* is, the stronger green is.

Δb* (delta b star) means difference of b* from the target in a color space.

b* means the color shade in the direction of yellow to blue in a color gamut.

It represents that, the larger b* is, the stronger yellow is, and the smaller b* is, the stronger blue is.

ΔCh (delta chroma) means difference of saturation from the target in a color space.

It represents that, the higher saturation is, the more vivid colors are, and the lower saturation is, the closer colors are to achromatic colors.

Delta-L*

Indicates the following:

• The gray CMY ratio that G7 defines

• An adjustment result of brightness gradation of the black scale

• The difference between the adjustment result and the target

Delta-L* graph

Displays the measurement result of Delta-L*.

CMY represents the adjustment result of gray.

K represents the adjustment result of the single color of K.

In comparison with the target, the farther the two values (CMY and K) in the plus direction, the lighter the color, and the farther in the minus direction, the darker the color.
