Ink Settings

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

The Ink Settings are available on Characterization and Project level.

In a project, the Ink Settings button is available on the Proof and Separation tabbed page. On the Proof page, you can edit the ink settings of all colors used in the project. On the Separation page, you can edit only the actual output colors as defined by the Target Color Space.

  • Click Ink Settings on the Tools & Actions panel to edit the ink settings.

Screening Settings (1).

These 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.

Usage (2).

The Ink Usage 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.
