NOTE: If an external instrument is connected, you are asked if you want to use the internal or external

instrument for calibration measurements. If you choose external, a line-up target is provided on-screen to

assist you in positioning the external instrument at the center of the screen.

StudioCal XML calibration

The StudioCal XML calibration method allows you to very precisely specify the calibration targets for a color

preset and calibrate up to three calibration presets in a single calibration session. StudioCal XML is an

extensible XML schema developed by HP for display calibration and modication. It was rst introduced with

the HP DreamColor Z27x Studio Display and has been extended to support the additional capabilities of this

display. While StudioCal XML

les are designed to be compatible between the dierent HP DreamColor Studio

displays, additional commands are available in this display that are not recognized by the Z27x. However, the

core calibration schema is designed to be compatible, and in many cases the same XML le can be shared

between dierent DreamColor Studio displays.

Instead of selecting calibration target options from menus, with StudioCal XML you dene these targets by

using XML objects and tags. The XML code is then saved as a le named StudioCal.xml and is stored on the

root of a USB ash drive. Flash drives formatted as FAT, FAT32, and NTFS are supported. See Using the

StudioCal XML schema on page 72 to learn how to use the XML schema to write calibration and other types

of scripts.

To calibrate using a StudioCal.xml le:

1. Create a le called StudioCal.xml le and copy it to the root (top) directory of a USB ash drive.

2. Insert the USB ash drive into one of the two DreamColor USB ports on the bottom of the display.

3. A message displays asking if you want to use the StudioCal.xml le on the ash drive to calibrate the

display.

If a rmware le is also found on the ash drive, the display asks you if you want to use the XML le for

calibration or install the rmware update. Select the XML le.

4. If an external instrument is connected, the display asks you if you want to use the internal or external

instrument for calibration.

If you select the external instrument, a line-up target is displayed to assist you in positioning the

instrument.

Calibration begins and will take approximately 3½ minutes when using the internal instrument. Calibration

time may be longer with some external instruments. Do not turn the display o during the calibration

process.

Calibration automation

Because the display is designed for color-critical work, it is important that the display remain calibrated, so

the display allows you to schedule automated calibration. This calibration can be scheduled at regular

intervals based on hours of use, physical weeks, or physical months. You can also specify when this

automated calibration takes place, ensuring that it occurs during o-hours and does not interrupt the

production process.

Scheduling automated calibrations

Use the Calibration menu to perform calibration scheduling. If you have not set the display’s internal clock

(Management > Time and date settings), the display prompts you to set the clock so that calibrations occur

at the correct time.
