Managing color on the Fiery 3850C
One example of how you might use this setting is with a page that contains some black
text on a light blue background. The background blue color is CMYK = 40%, 30%,
0%, 0% and the black text is CMYK = 0%, 0%, 0%, 100%.
• With Black Overprint On, the final text portions of the page are overprinted, or
combined with the underlying colors. This results in CMYK = 40%, 30%, 0%,
100% for the color used for the text. There is no transition in the cyan and magenta
toners, and the quality of the output is improved since it will not show artifacts near
the edges of the text. The option also works with text defined in the RGB color
space, that is RGB = 0, 0, 0.
• With Black Overprint Off, the border of the text 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). On many devices, this transition causes visible artifacts because of
the practical limitations of the printer.
Spot Color Matching
The Spot Color Matching option provides automatic matching of PANTONE colors
with their best CMYK equivalents.
•
On
—The Fiery 3850C uses a built-in table to generate the closest CMYK matches of
PANTONE colors your printer can produce. (New tables are generated when you
add new output profiles.)
N
OTE
:
Spot colors not included in the built-in table are treated as CMYK.
•
Off
—The Fiery 3850C uses the CMYK equivalents defined by your application to
print PANTONE colors.
For jobs that include PANTONE spot colors, set Spot Color Matching to On unless
you are printing press simulations. In that case, set Spot Color Matching to Off and
choose the appropriate CMYK Simulation setting (see page 1-6).
N
OTE
:
You can use the Spot Color Matching option only when printing composites,
not when printing separations.
