The Smart Media Definition (SMD) includes settings related to color management. For specific customers or jobs, sometimes you need to change settings to meet specific quality requirements. Over time, a new output ICC profile may be required.

In this situation, a color management expert needs to use the OVERRIDE COLOR dialog to create a new SMD with the required setting or profile changes.


The Override Color dialog can be accessed using the engineer "Spanner" icon in the Smart Calibrator's Start Calibration screen.

Document controls

The settings that can be changed include:

  • Override color management in PDF
  • Preserve 100% black
  • Keep text black
  • Color manage gray as CMYK

Override color management in the PDF

When enabled, the input ICC profiles override any found in the document. When not enabled, the Input ICC profiles are used only where they don't already exist in the document.

Preserve 100% black

When enabled, the black‐only part of your input is no longer converted to a CMYK‐equivalent color. This option is particularly relevant for black text because it avoids colored fringes.

Keep text black

When enabled, this setting keeps black text objects as process black.

When "Preserve 100% black" is enabled, this setting is enabled implicitly.

Color manage gray as CMYK

When enabled, monochrome (gray) data uses the selected CMYK input profile and is color managed as CMYK. When this option is selected, the Gray ICC profile setting becomes unavailable.

Output Rendering intents

The following rendering intents can be set:

  • The main (default) rendering intent
  • Override intents
    • CMYK images
    • RGB images

Intent hierarchy

You can set rendering intents in the document being printed, or in Smart DFE's color management settings.

If there are rendering intents set in the document, they take priority over the main rendering intent setting.

If the override intents are set, they take priority over all other intents.

Main rendering intent > Is overriden by > Rendering intent in document > Is overriden by > Override intents.

When "Color manage gray as CMYK" is checked, the CMYK images intent is also used as an override for gray images.

Absolute colorimetric

Any color that the device can reproduce (with the intended setup and viewing conditions) is reproduced exactly. Colors outside the device gamut are mapped onto a "nearby" point in the gamut. There are various ways in which a color might be out of gamut. For example, it could be too saturated, lighter than the paper color, or darker than the darkest imageable patch.

Colorimetric reproduction is appropriate where an exact color match is required. For example, you may choose a colorimetric strategy when you are reproducing a logo in corporate colors.

Relative colorimetric

This style aims to reproduce colors exactly, except that the luminance (how light or dark a color is) is scaled so that the darkest possible color is mapped to the darkest imageable color; the lightest possible color is mapped to the paper white. This style may change the hue (that is, the degree of redness, blueness, and so on) of any color, and is almost certain to affect the luminance of most colors.

Some scanners and applications produce data that has been adjusted so that the lightest and darkest points are encoded as maximum and minimum lightness. For interpreting this kind of image, the relative colorimetric style is appropriate.


This style maps the entire device‐independent color space onto the gamut of the printer; it compresses the range of in‐gamut colors to make room for out‐of‐gamut colors. It is appropriate for rendering photographs and similar reproductions of natural scenes.


This style specifies that the saturation of the colors in the image is preserved, perhaps at the expense of accuracy in hue and lightness.

Input profiles

The Override Colors dialog gives an expert user the ability to replace input ICC profiles, including:

  • RGB profile
  • CMYK profile
  • Gray profile

When an SMD is first created, a set of default input profiles is added.

If no profile is found in the SMD, the setting shows as "None"; SPC chooses an appropriate default.

Output profiles

The Override Colors dialog gives an expert user the ability to replace and add output ICC profiles, including:

  • Printer profile
  • Emulation profile

When an SMD is first created, a set of default input profiles is added.

If no output profile is found in the SMD, the setting shows as "None"; SPC chooses an appropriate default.

When Emulate another printer is enabled, the emulation profile is added to the color management chain (between the input profile and printer profile). 

Saving changes

If any required ICC profile is set to "None", the SMD cannot be created. Adding the required profiles enables the Create new media... button. 


This tab allows the user to create an ICC profile using default settings.

It also allows the user to view the gamut of the ICC that is being used.
