InkTune Sets Overview
This is the list of all the available ink-saving presets.
Select a preset in the list to see more information in the pane on the right. Use the sliders to change the values of the presets.
In Neutrals
These settings control GCR in the neutral tones.
Start K
The value at which GCR in neutral tones kicks in. Typically, this should be 0%.
GCR Mid tones
This slider is used to control the GCR curve between the Start K point and the blackpoint.
GCR Blackpoint
Sets the percentage of GCR applied to the neutral tones. Blackpoint is the darkest point as defined by the press profile.
In Colors
These settings control GCR in the colored tones.
Chroma Zone
Defines the Chroma value from which point onwards the GCR Chroma % is applied. For colors with a Chroma value below the set point, the amount of GCR is gradually set between the GCR % of the Neutral set up, and the GCR Chroma %. Any color with a Chroma value higher than the Chroma Zone value, will be treated with GCR Chroma % value.
GCR Chroma
Sets a different amount of GCR for (saturated) color than for neutrals. The GCR Chroma % value will be applied to any color with a Chroma value higher than the Chroma Zone value.
Multi-Colors
These settings control GCR in the multi-colored tones. Refer to
Chroma Zone and
GCR Chroma for parameter descriptions.
Ink Limits
These values set the limits for controlling GCR. Select the Override Input Ink Values check box to force ink save for colors with higher ink loads than the press profile.
Override Input Ink Values
This check box can be selected to force colors with higher ink loads than the press profile to apply ink saving up to a new maximum ink load — for both the total ink load and for max K separately.
NOTE: When this option is selected, the label of the Max K parameters changes from GCR Max K to Force Max K and the Ink Limits drop-down list is enabled.
When this check box is cleared, the Max K slider defines the maximum value for K to be used during the GCR calculation. However, input colors that already contain more K than the result after GCR calculation, will not be changed in order not to waste ink.
Force Max K
The maximum amount of black ink that may be used for ink saving.
Ink Limits
Two options are available in the drop-down list:
Total Ink Limit (TIL/TAC)
Set a total ink limit so that all colors will have ink saving applied with that value as maximum total ink value.
Dynamic Low-ink Coverage (DLC)
Selecting this option displays advanced settings to save ink by adjusting the color gamut of a profile and omitting zones where color differences are difficult for the human eye to distinguish. Sliders with a maximum value of 400% are displayed for the following ink zones:
•Primary CMYK
•Secondary RGB
•Secondary CK, MK, YK
•Tertiary CMY
•Tertiary CMK, CYK, MYK
•Equal CMYK.
