Color Accuracy

These are two areas you should review when
troubleshooting a color accuracy problem:

Configuration

Check the color emulation selected in the driver. Make
sure the color information is adjusted for the current
color setup. See

Color Accuracy Configuration

.

Printing color with PostScript (HP Designjet
5000PS)

Most graphic design applications can define color using
three methods:



CMYK.



RGB.



Pantone.

CMYK Workflows

Traditional workflows define the color in the
CMYK space. To obtain optimal results,
CMYK must be adapted to the target printer
which receives the data, different printers will
produce different color from the same CMYK
data.

In some situations the CMYK data in your document
will not be suited to your printer. Two typical situations
are:



The document was optimized for a certain printer,

and now it has to be produced on a different
printing device.



The document is being optimized for a printing

press, but it is necessary to produce a check print
using a less-expensive printing device.

To process CMYK data which is not intended for the
printer, the HP Designjet printers provide color
emulation modes. The emulation must be enabled in
the PostScript driver, in the “Printer color management”
dialog box:

Standard emulations:

– SWOP (United States),

– EuroScale (Europe),

– DIC (Japan) and

– Toyo (Japan).

CMYK data is frequently designed for these standards.
If there is no information as to how the
CMYK data was defined, these standards
are a good assumption.
