1 ProofMate™ (ProofReady) Plugin for HP Printers
38 AG50241 Rev. 4
1.8.1 Calibrating the printer
We recommend calibrating the printer for each device type and paper/resolution that
you use. To provide a useful starting point, the plugin is supplied with a number of
calibration profiles which define the ideal or ‘reference’ state for the printer. The pro-
files are installed in
…RIP_folder\SW\Config\Devices\DevCalibration\, one
for each device type.
The response of your printer (the ‘user printer’) may differ from the reference printer.
To obtain optimum output quality you need to calibrate the printer so that it responds
in the same way as the reference printer. The adjustments needed to correct the user
printer so that it matches the reference printer are defined in a calibration set. The sup-
plied calibration profiles are distinguished from user-generated calibration sets by
being enclosed in parentheses, like these
( ).
The way in which you calibrate your device depends on the Harlequin RIP version
that you are using. For details on calibration in the Eclipse Release, see Section 1.8.1.1
on page 40. For details on calibration in RIP 5.x versions, see Section 1.8.1.2 on page
42.
1.8.1.1 Eclipse Release calibration procedure
To ensure accurate calibration, it is recommended that three targets are printed and
measured. For subsequent recalibrations, an accurate profile can be achieved with one
pass, as described in Section 1.8.1.3 on page 43. Before you begin calibrating, load the
correct paper and initialize the printer according to the manufacturer’s instructions.
Print and measure an initial target
1. Create a page setup in the Harlequin RIP with the following options:
•
Device—select the correct device
•
ProofReady—select (None)
• Calibration—select the paper/resolution type
2. In the Harlequin RIP, click
Output > Print Calibration to open the Print
Calibration window. From the list choose your page setup then click
Print uncalibrated target.
3. Measure the printed target with Genlin, or your preferred calibration program.
Genlin is installed with the Harlequin RIP and is described in the RIP Manual.
