Simulation
Choosing
colors in
PostScript
applications
If you are using the KX-P8420 to print proofs for an offset press job or to
simulate another print device, select the appropriate CMYK Simulation
setting. The CMYK Simulation setting specifies the offset press standard or
other color gamut that you want to simulate.
The CMYK Simulation setting you should specify depends on the press
standard for which the CMYK data was separated. For example, for images
that were separated for SWOP-Coated paper, select SWOP-Coated as the
CMYK Simulation setting. Select SWOP-Coated to simulate printing to a
standard American offset press; Euroscale to simulate a European offset
press, or DIC to simulate a standard Japanese offset press. For images that
were separated using a custom separation (such as a device-specific
separation or a separation produced with an ICC-profile), select None as
the CMYK Simulation setting
With PostScript applications, you can create colors using any of the color
models supported by the application. All PostScript applications support the
CMYK model; some also support the RGB model and other color models
based on monitor display values. PostScript applications also allow you to
select named colors using one or more color libraries, such as PANTONE.
The important thing to remember when creating or choosing colors is that
the displayed versions of those colors may not match KX-P8420 output or
the output of identically defined colors from other color print devices. For
this reason, you should use color matching to ensure predictable color
printing results with the KX-P8420.
Color reference files
Two color reference files have been included on the KX-P8420 Driver &
Utility CD-ROM: a CMYK color reference file, and a PANTONE color
reference file.
If you install the printer driver using the installer's typical or compact
installation options, the CMYK and PANTONE color reference files are
automatically copied to the KX-P8420 directory on your hard disk. If the
color reference files have not been installed, insert the KX-P8420 Driver &
Utility CD-ROM into your CD-ROM drive and use the installer's custom
option to select the reference files to copy to disk. You can also navigate to
the appropriate directory, and manually copy the files to your hard disk.
