Note: The server must be running before you start the Halftone Management System client. Starting the Halftone Management System client On the front panel, open the extended menu above the InfoPrint icon, and click Start Calibration GUI . You can also start the Halftone Management System client from the command line: 1. Enter: ./usr/lpp/pd/ipcal/bin/runcalib& From the client screen, a pop-up Halftone Management System window announces Starting the Halftone Management System Client. If you invoke the Halftone Management System client before starting the Halftone Management System server, InfoPrint Manager displays an error pop-up message: Error in connecting to host fully_qualified_server_name -- A remote host refused an attempted connect operation. To resolve this problem, you must close the Halftone Management System client window and restart the client after you start the Halftone Management System server. 2. Once you have completed these steps, see "Defining InfoPrint servers to the Halftone Management System client" on page 30. Calibrating a densitometer The reflection densitometer must be calibrated to provide accurate density readings. Prior to using, you must follow the instructions that are provided by the manufacturer to calibrate the densitometer. The densitometer used must comply to the spectral responses defined by ANSI PH2.18 - 1985 and ISO 5/3 - 1984. The densitometer should not have a polarizing filter. The Greytag Macbeth model D19C has a polarizing filter and should not be used. Densitometers which are appropriate to use include the X-Rite Model 504, 508, or 400B. The densitometer should be used in Absolute Density mode for measurements. The following procedure describes how to calibrate the X-RITE 400B (1060) densitometer, using the Reflection Reference Card (part number 400-62). Since the X-RITE 400B is now obsolete, the following information is provided as reference. You use the Reflection Reference card to calibrate the densitometer. You will use only the circular patches labeled 1 (white reference) and 3 (black reference). The densitometer should be calibrated periodically, or whenever the instrument displays RECAL. You should store the Reflection Reference Card in its envelope. 1. Press the FUNCTION and ENTER keys in sequence, then release. After the version and copyright notices appear, the display will show N cal O Y. 2. Press the ZERO key and release. After the version and copyright notices appear, the display will show N qcal Y. 3. Press the FUNCTION key and release. SET LO is displayed momentarily, followed by X.XX, where X.XX should be the white patch ORTHO value from the Reflection Reference card. 4. If X.XX matches the white patch ORTHO value for your reflection reference, press the ENTER key. If X.XX does not match, hold down the ZERO key and Chapter 2.
