When an application sends a Pantone color to the printer, it can use two methods  Pantone colors as spot are defined with their name, so that the printer can select how to best emulate that Pantone color.  Pantone colors as composite colors are defined with a CMYK value. Since CMYK values are device-dependent, the CMYK for the Pantone composite color must be adapted to the target printer. Most applications contain CMYK definitions of Pantone colors optimized for the SWOP or EuroScale standards. If the application does not allow selection of this CMYK, and the printer CMYK does not emulate these standards, the output will not match well with the Pantone colors. If the Pantone colors are defined as spot colors, the HP Designjet printer will produce the best match through the Automatic Pantone Calibration mechanism. If the best CMYK for the Pantone is not known, it is recommended that Pantone colors are defined as spot. Only Pantone Coated colors are reproduced in an HP Designjet. Using ICC Profiles The International Color Consortium (ICC) color profiles that are provided with the HP Designjet 5000PS are identical to the color profiles that the internal PS RIP uses, although the latter converts them to PostScript Color Rendering Dictionaries internally. To use the ICC profiles outside of the internal PS RIP, the application and the driver must be configured correctly for good results. Make sure the ICC profile for the correct printer model (DJ 5000PS), ink type (imaging or UV), media, and print quality is selected in your application, and that it is being used to convert RGB or CIELab images to CMYK. Choose the correct rendering intent for your type of job: Perceptual for photographic type images, Colorimetric for logos and proofing, and Saturation for computer graphics type images. Make sure the application is sending device CMYK colors to the printer, not calibrated color. For instance when printing from PhotoShop 5.x, select the profile and

Pantone Workflow
Pantone colors are identified by their name, and the
appearance for the color is defined by Pantone.
Pantone calibrates HP Designjet printers so that they
can produce the best match of a Pantone color.
When an application sends a Pantone color to the
printer, it can use two methods
Pantone colors as spot are defined with their
name, so that the printer can select how to best
emulate that Pantone color.
Pantone colors as composite colors are defined
with a CMYK value.
Since CMYK values are device-dependent, the CMYK
for the Pantone composite color must be adapted to the
target printer. Most applications contain CMYK
definitions of Pantone colors optimized for the SWOP
or EuroScale standards. If the application does not
allow selection of this CMYK, and the printer CMYK
does not emulate these standards, the output will not
match well with the Pantone colors.
If the Pantone colors are defined as spot colors, the
HP Designjet printer will produce the best match
through the Automatic Pantone Calibration mechanism.
If the best CMYK for the Pantone is not known, it is
recommended that Pantone colors are defined as spot.
Only Pantone Coated colors are reproduced in an
HP Designjet.
Using ICC Profiles
The International Color Consortium (ICC) color profiles
that are provided with the HP Designjet 5000PS are
identical to the color profiles that the internal PS RIP
uses, although the latter converts them to PostScript
Color Rendering Dictionaries internally. To use the ICC
profiles outside of the internal PS RIP, the application
and the driver must be configured correctly for good
results. Make sure the ICC profile for the correct printer
model (DJ 5000PS), ink type (imaging or UV), media,
and print quality is selected in your application, and that
it is being used to convert RGB or CIELab images to
CMYK. Choose the correct rendering intent for your
type of job: Perceptual for photographic type images,
Colorimetric for logos and proofing, and
