11.1.1 Recalibrating the printer
To maintain printer calibration accuracy, you should periodically recalibrate your HP printer. This is particu-
larly important if the paper, ink, or some other variable (including ambient room conditions) changes.
To recalibrate the printer, do the following:
1. Click Output > Print Calibration to open the Print Calibration window.
2. Select the correct page setup you are using to output to the installed paper, and click Print calibrated target.
3. Measure the target with Genlin
4. Open the Calibration (Dot Gain) Manager and select the calibration set assigned to the page setup. Then
click Edit from calibrated target.
5. In the Edited calibrated target dialog, click Import > Import to read the calibration data. You may also wish
to specify a new profile name, to indicate, such as
HP Photo Gloss-Aug2007, to indicate the date the
profile was updated.
6. Click OK to save the modified and updated profile. If you have changed the name of the calibration profile,
remember to edit your page setups to use the new calibration profile. If you have not changed the name,
you do not need to do this.
11.2 Creating and installing ICC profiles
To create and install a new ICC profile, do the following:
1. “Create a suitable page setup” on page 25.
2. “Print and measure an ICC target” on page 26.
3. “Install the ICC profile in your RIP” on page 26.
11.2.1 Create a suitable page setup
To process the ICC profiling targets and output them to a printer, you will need to create a page setup which uses
the correct printer model, media type, ink and output quality. The page setup must not have any color manage-
ment or calibration options selected; these should be set to
(None) or (No color management) as applicable.
Or, if you have created a “Golden State” profile for the printer, using Global Graphics’ SetGold utility for exam-
ple, you may select the profile and use it as a suitable reference state for the printer.
Having created a suitable page setup, use it to print the ICC profiling target and measure it using an appropriate
software package.
The exact procedure you should use varies from package to package, but it is possible to give some general
hints:
• Total area coverage: For some paper types the total area coverage should be limited. This depends on the
paper, ink type, resolution and screening used, but a good guide is to limit the coverage for coated media
(Premium) to 280%, whereas matte media should be around 320%. Some experimentation may be
required to determine the optimum setting.
• Number of patches: Although the number of color patches printed and measured is not always a guide to
color quality, it is generally true that printing more patches produces better results for any given ICC pro-
filing package.
Having created the ICC profile, install it using the menu option Color > Install ICC Profile. In the Linear
Calibration From menu in the Install ICC Profile dialog box choose either:
•
Linear if the page setup you used contained no color management data (raw state); or
