Ink Settings

The ink settings are required for separation profiles and DotProof profiles. For ContoneProof profiles, the ink settings are not relevant.

You can define the ink settings for characterizations and projects. In a project, under the Proof tab, you can define the ink settings of all colors used in the project. Under the Separation tab, you can define only the actual output colors as defined by the Target Color Space.

On characterization and project level, you can access the ink settings via the Tools & Actions panel on the right: Tools & Actions > Tools > Ink Settings


This screenshot highlights the Screening area of the ink settings.

The Screening settings are mandatory for calculating DotProof and separation profiles. Including the imagesetter resolution, the screening settings should match the actual target printing conditions you want to simulate, e.g. as used for creating the 1-bit files of the iteration chart (see "Optimizing the Profile Quality").

Different screening grids serve to avoid moiré patterns. If you want to print with more than four inks, you can use the same grid for complementary colors, as complementary colors normally do not overprint. For example, Red can have the same grid as Cyan, and Green the same as Magenta. If the colors strongly differ in lightness, however, they should use different screening grids.

The screen angles of the separate channels should be shifted at least by 15° towards each other for avoiding moiré effects. Instead of defining each angle separately, you can use one of the typical presets (> Screen Configuration).

If the screening settings used when producing the 1-bit files differ from the ones in the characterization (e.g. when using 1-Bit Creator in GMG ColorProof), the first ones should be used.


This screenshot highlights the Usage area of the ink settings.

The Usage setting defines how a color will be handled during profile calculation. It also influences the choice of patches and the total number of patches in iteration test charts used for DotProof profiling.


This screenshot highlights the Overprint matrix of the ink settings.

The overprint behavior depends on the Screening and Usage settings.

In case of AM screening, colors set to the same screening configuration will overprint only with solids by default. For example, if Cyan and Red are both set to Configuration 1, Cyan will only print with solid Red and vice versa. In the overprint matrix, this is indicated by the filled Suppress Raster-Raster overprints icon ().

Suppress Raster-Raster overprints

With the  Suppress Raster-Raster overprints setting, Cyan will only print with Red and vice versa.

You can click the icons in the overprint matrix to change the overprint behavior. For example, you could prevent Cyan and Red from overprinting by setting them to Suppress all Overprints ().

Suppress all overprints

With the  Suppress all Overprints setting, Cyan and Red will not overprint.

In case of FM screening, there are no predefined screening configurations available. Instead, you can define the overprint behavior for each color individually and without limits via the overprint matrix. For example, you could allow overprinting for all colors by setting each of them to All overprints, no restrictions ().

All overprints, not restrictions

With the  All overprints, no restrictions setting, colors are allowed to overprint without any restrictions.

When calculating separation rules, the Total Area Coverage and the overprint behavior defined in the project are taken into account (see "Creating Color Definitions"). This prevents overinking and moiré effects in the print production.
