1 ProofMate™ (ProofReady) Plugin for HP Printers
42 AG50241 Rev. 4
Pre Eclipse Release RIPs
In this case both the
Color and Calibration menu options in the
page setup must be set to
(None).
Eclipse Release or later RIPs
In this case both the
ProofReady and Calibration menu options
in the page setup must be set to
(None), and you must choose
(No color management) from the Color menu.
Note: The printer in this ‘raw state’ may not be a suitable basis for creating pro-
files.
Golden State You can use a temporary calibration profile or calibration set
in your page setup that supplies a reference state for the
printer. Use this calibration profile or calibration set to pro-
duce the ICC profile and remove it afterwards.
The option that you choose affects the ICC profile and how you install it.
Having created a suitable page setup, use it to print the ICC profiling target and mea-
sure it using an appropriate software package.
The exact procedure you should use will vary from package to package, but it is possi-
ble to give some general hints:
• Total area coverage: For some paper types the total area coverage should be
limited. This depends on the paper, resolution and screening used, but a good
guide is to limit the coverage to 320% for uncoated papers and to 400% for
coated papers. Some experimentation may be required to determine the opti-
mum setting.
• Black generation: The presence of black ink in highlights can in some cases
be objectionable and can introduce an unnecessarily grainy appearance to some
images. Select a setting which images black only in dark regions. (If it is not
clear which settings will image black only in dark regions, select the minimum
amount of black generation allowed by the ICC profiling package.)
• Number of patches: Although the number of color patches printed and mea-
sured is not always a guide to color quality, it is generally true that printing
more patches produces better results for any given ICC profiling package.
