Acquiring Color Measurement Data For Any Color Chart (Mac OS X) iPF6450 Setting Item Reduce Drying Time Illumination Observer Angle UV Cut Color Measurement Value Details If the number of patterns is small, drying will finish in a shorter amount of time than the time configured in the Preferences dialog box. If this happens, the drying time will not be reduced even if the Reduce Drying Time check box is selected. Select the illumination from D50, D65, and A. Selects the observer angle. Selects whether or not UV cut is used. Saves the color measurement data for the color measurement values where the check box is selected. The Lab check box cannot be cleared. • If you want to enlarge the color chart pattern or configure the color chart drying settings in detail, click the Settings Note button to display the Color Measurement Preferences di- alog box. Color Management Setting Item Pattern Size Details Selects the pattern size of the color chart. We recommend Larger when you want to prioritize the color measurement precision. Drying Method Choose Ventilation Fan to dry using the ventilation fan or Air Drying to dry without using the ventilation fan. Ventilation Fan Configures the drying time and airflow for the ventilation fan. Color Calibration Management Console (Mac OS X) Time Configures the drying time for the ventilation fan for each pattern. The number of lines that are dried at one time by the ventilation fan varies depend- ing on the size selected in Pattern Size. As the time increases, the adhesion of the ink improves and the color tones become more stable. Reduce Drying Time Selecting this check box reduces the drying time. Once the time configured in the Color Measurement Env. sheet in the Preferences dialog box has elapsed, color measurement proceeds without performing any further drying with the ventilation fan. Specify a time that offers sufficient drying by air drying in the Preferences dialog box. If you perform color measurement while the ink is not dry, the measurements may not be correct. The Preferences dialog box is displayed when you click Preferences in the imagePROGRAF Color Calibration Management Console menu. If the number of patterns is small, drying will finish in a shorter amount of time than the time configured in the Preferences dialog box. If this happens, the drying time will not be reduced even if the Reduce Drying Time check box is selected. Airflow Selects the airflow of the ventilation fan. Air Drying Sets the period between the color chart being printed and the color measurement starting. 906 If the Dry Separated Chart check box is selected, printing and air drying are repea- ted for each separated color chart. This makes it harder for the color charts to be- come scratched or soiled, but also increases the time taken by the operation. User's Guide
