copy the calibrated halftone set from the c:\Program Files\IBM\InfoPrint Manager\config\custom directory to the c:\Program Files\IBM\InfoPrint Manager\config directory or copy the calibrated set from the c:\Program Files\IBM\InfoPrint Manager\config\custom directory together with the threshold array files of the same family from the c:\Program Files\IBM\InfoPrint Manager\config directory. The threshold array files have ta in their name. Rename the entire resulting set by adding a custom version and copy it to the c:\Program Files\IBM\InfoPrint Manager\config directory. Then change the version of the toner for that printer by setting the toner-version actual destination attribute with the custom value. For example, printer_model.ibm106lpi.ta.ps could be renamed to printer_model.ibm106lpi.ta.ps.custom1 and then the toner-version attribute set to custom1. Measuring optical density with a densitometer This procedure describes how you can measure optical density using the XRITE 400B Densitometer. While you can use other densitometers, this procedure has been verified with this particular make and model. Make sure that the density readings are absolute, not paper reference. 1. Press the FUNCTION key until DEN appears. If DEN-R appears, press the ZERO key and try again. 2. Center the circle on the base of the densitometer over the area to be measured. 3. Push the head down and release it to measure the Optical Density (OD). The density reading will appear as X.XXD. 4. Record the X.XX value as it is displayed. Several measurements should be taken at different representative locations on each gray patch and averaged to obtain an accurate OD value. Alternately, you can enter individual measurements into the calibration value screen and have the averaging performed automatically. Specifying a halftone for printing on the InfoPrint Manager server You can use a particular halftone for printing a grayscale file through either "Printing from InfoPrint Submit Express" interface or the Printing from the command line. Note: The Halftone Management System does not need to be running when you print the job. Printing from InfoPrint Submit Express You can print using a particular halftone for printing a grayscale file from a job ticket (name.jtk file) in InfoPrint Submit Express. Begin by selecting a value in the Halftone field of the Look tab. Note that all halftones shipped with the product have the term 'ibm' prepended to their identifier. If you are accessing this interface for the first time, all of your previous default calibrations will have 'ibm' attached to the name. InfoPrint Manager lets you determine output appearance on a job-by-job basis by setting a default halftone in a default document or job object. Note: InfoPrint Submit Express is part of the InfoPrint Manager Print-on-Demand feature. 290 InfoPrint Manager for Windows: Procedures
