ICC profiles

; Note

It is not possible to influence the settings for black generation at this moment. The ICC profiles that

Color Kit generates, alwayswill use minimal black.

Using Dot gain simulation curves

When exporting to an ICC profile, it is possible to use 'dot gain simulation' curves. These curves will

only have an effect if the profile is used as a reference profile.

This type of dot gain simulation can be compared to the dot gain simulation used in Color Strategies.

Using Refinement curves

When exporting to an ICC profile, it is also possible to use 'refinement' curves. These curves will have

an effect only if the profile is used as an output profile.

Refinement curves can be used to fine-tune the output colors.

Example

If the reds on your calibrated proofer are too strong, dgc curves can be used to cut back the magenta

and yellow. This information will be stored in the ICC profile.

Using Black Generation

When exporting a CMYK profile, the Separation tab will be enabled. This is where you can specify a

black generation preset, as described in the chapter Black Generation in ICC Profiles.

Notes on exporting to an ICC profile

When exporting to ICC, bear in mind that different CMS vendors will make different colormatches,

even if the same profiles were used. These differences can be caused by the fact that:

• ICC profiles do not contain measured data points. The relation between data points in the profile

and the measured data points is profile vendor specific.

• The accuracy of the algorithms and the techniques that are used in the CMM and by the different

answers to the following questions:

• What to do with out-of-gamut colors?

• How to interpolate between the measured points in the Profiles?
