Host-Based Icc Color Matching; Dynamic Contone Screening - Konica Minolta magicolor 2550 Series Technical Manual

Select "ICM" in the
printer driver to de-
activate the
printer's internal
CMM and use
host-based color
matching.
Select "Custom" from the printer driver to
perform Dynamic Contone Screening
manually.

Host-Based ICC Color Matching

You may prefer to use the color matching system built into such
applications as QuarkXPress, PhotoShop, and Illustrator. To support
host-based color matching, KONICA MINOLTA provides a Windows ICM
printer profile to define the printer's color space to the software's color
matching system. To activate this function, select "ICM" in the printer
driver and then choose the preferred ICM method and rendering intent.

Dynamic Contone Screening

Dynamic Contone Screening is a convenient color tool that optimizes
printed output by analyzing page elements and then automatically
adjusting color based on these elements.
However, if you prefer, you can also perform this same function
manually, adjusting the color settings for each page object—Images,
Text, and Graphics. To use this hands-on method of color matching,
select "Custom" in the printer driver and then choose the appropriate
settings.
For each page object, the following settings are configurable:
Device profile—The device profile, or RGB Source, defines the
host input. Select from "sRGB" (for Windows operating systems),
"Apple RGB," "Adobe RGB," "Color Match RGB," and "Blue
Adjust RGB."
Rendering intent—During color transformation from the host to
the printer, the rendering intent, or RGB intent, determines the
type of color matching that will be used to ensure graphics are
bright and images are natural. Select from "Vivid" (ideal for sharp
graphics and text), "Photographic" (best for images), "Relative,"
or "Absolute Color."
Halftone setting—The halftone setting defines the screening
method used. You will find that selecting the "Smooth" setting for
images will produce fewer lines per inch (lpi), smoother
gradations, and less banding. Selecting the "Detail" setting for
text results in a higher lpi, crisp edges, and sharp lines.
The magicolor 2550 Series printers also include built-in profiles for
simulating printing press output. Select from
SWOP, EuroColor, DIC, Toyo, and Commercial
press simulations.
