interpreted in the default CMYK and RGB modes. The sRGB profile matches the default RGB
mode (sRGB) which is enabled with the Screen Match or Automatic Color Smart II setting in
either the PCL or PostScript driver. The CMYK profile is based on the default mode, which is a
SWOP simulation with a CMYK Inkset setting of FAST in the PostScript driver. These profiles
can be used for color conversions in a color-managed workflow.
PANTONE®* color profiles
Automatic PANTONE®* Calibration is the default setting for HP Color LaserJet printers. This
feature automatically converts PANTONE®* colors to optimal color values for the printer by
recognizing the PANTONE®* color name or number in the data stream sent to the printer. The
feature is activated when printing colors that were chosen using the PANTONE®* Color picker in
supported graphics applications.
Applications known to generate PostScript files with graphic objects preserving the PANTONE®*
name are listed below:
• Adobe Illustrator 7 & 8
• Adobe PageMaker 6.5
• CorelDraw 7, 8 & 9
• Deneba Canvas 5 (see note below)
• Macromedia Freehand 7 & 8
• Micrografx Designer
• Quark Xpress 3 & 4
NOTE: Deneba Canvas versions 6 and 7 are not compatible with the
Automatic PANTONE®* Calibration feature.
The Automatic PANTONE Calibration feature only applies to graphic objects, not picture (raster)
data such as scanned images and TIFF files. Adobe PhotoShop, for example, being a raster
image editor, is not on the above list of applications that support the Automatic PANTONE®*
calibration feature.
Some applications substitute CMYK values to the printer if they cannot provide PANTONE®*
names. If your application does not pass the PANTONE®* names to the printer, the application
will substitute default CMYK values to be printed for each color. In this case, the accuracy of
color matching will depend on the ink emulation selected - FAST, SWOP, Euro standard, or DIC
(Dainippon). If your application does not pass the PANTONE®* names to the printer, the custom
CMYK values created by PANTONE®* for this printer are available in the manual PANTONE®*
palettes.
PANTONE
® * Application Palettes are available on the web for:

• PhotoShop 3–5.5
• CorelDRAW 6–9
• Micrographics Designer 6–7
