Spot color matching
The
Spot color matching
option provides automatic matching of spot colors with their best CMYK equivalents.
•
On
- The Fiery ES uses a built-in table to generate the closest CMYK matches of spot colors your printer can
produce. (New tables are generated when you add new output profiles.)
With Spot-On, the Fiery ES uses the CMYK matches determined through Spot-On.
•
The
Use spot group
menu allows you to select a spot color group that Fiery ES searches first for spot color
definitions during file processing. When new spot color groups have been created in
Device Center
>
Resources
>
Spot Colors
, the new groups are listed in the
Use spot group
menu. If a spot color is not found in the selected list,
the Fiery ES searches all other spot color groups for a matching spot color name. If the name is not found, the
spot color is rendered with the alternate color in the document.
•
Off
- The Fiery ES processes spot colors as CMYK data and uses the alternate color space provided by the spot
color. By default, most applications use the CMYK equivalents defined by the spot color manufacturer, such as
PANTONE. These are the same CMYK equivalents used by applications that include spot color libraries.
Note:
Spot colors that are not included in the built-in table are processed with the Alternate Color Space.
For jobs that include spot colors, turn
Spot color matching
on unless you are printing press simulations. In that case,
turn
Spot color matching
off and select the appropriate
CMYK source
.
For PDF and PostScript jobs that include spot colors that are not in the built
‑
in table, turning
Spot color matching
on causes the alternate color space to be used. The Fiery ES references the built
‑
in table to generate the closest
CMYK matches of the original spot color.
Note:
Use
Spot color matching
only when printing composites, not when printing separations.
Substitute colors
Substitute colors are colors that, when called for in a document by their RGB or CMYK values, are substituted with a
different color that is defined in the Spot-On color dictionary. This permits exact color control and overrides
individual RGB and CMYK colors.
Spot-On allows you to create a list of substitute colors. To enable substitute colors for a job, turn on the
Substitute
colors
option.
Note:
You cannot use
Substitute colors
at the same time that you use
Postflight
.
When you use
Substitute colors
at the same time that you use
Spot color matching
, be sure that the CMYK color
that you want to replace with a substitute color is not a CMYK color that is also defined as a spot color. Otherwise,
the spot color may be replaced with the substitute color, which may not be the result that you expect.
For more information about creating and using substitute colors, see
