One example of how you might use this setting is a page that contains black text on a light
blue background. The background blue is CMYK=40%, 30%, 0%, 0%. The black text is
CMYK=0%, 0%, 0%, 100%.
blue background. The background blue is CMYK=40%, 30%, 0%, 0%. The black text is
CMYK=0%, 0%, 0%, 100%.
• With Black Overprint set to Text or Text & Graphics, the final text or text/graphic
portions of the page are overprinted, or combined with the underlying color. Black colors
generated by applications (for example, RGB=0, 0, 0 or CMYK=0%, 0%, 0%, 100%) are
printed using the black toner. This means that black text and line art does not exhibit
halftone artifacts (as long as the digital press is calibrated correctly). No transition in cyan
and magenta toners occurs. The quality of the output is improved, since it does not show
artifacts near the edges of the text defined in the RGB color space (RGB=0, 0, 0).

• With Black Overprint Off, the border of the text or text/graphics is on an edge that has
cyan and magenta toners on one side (outside the text) and black toner on the other side
(inside the text). This transition may cause visible artifacts due to the practical limitations
of the digital press.

Combine Separations
The Combine Separations setting specifies how to print separated CMYK data. With Fiery
Graphic Arts Package, you can combine an unlimited number of spot color separations along
with the CMYK separations.

•
Off
prints each separation individually.
•
On
combines separations as a single, composite-color document, and automatically makes
the settings for the following print options: Color Mode (CMYK), Rendering Style
(None), Pure Black Text/Graphics (Off ), and Spot Color Matching.

CMYK Simulation Profile
The CMYK Simulation Profile print option allows you to print press proofs or simulations.
This setting specifies the offset press standard or other color printing device that you want to
simulate. This option affects CMYK data only.

With Windows printer drivers, you can also view an unlimited number of custom Full
simulations created using ColorWise Pro Tools. On Mac OS computers, you can view up to
10 Full custom simulations. The number of custom simulations is limited by the available
disk space on the Fiery EXP6000/EXP5000.
