Maximum Density Adjustment

Adjust the maximum density for each of Y, M, C, and K colors.

Adjustment range: (Light) -10 to +10 (Dark) for each of <Yellow>, <Magenta>, <Cyan>, and <Black>

NOTICE

  • The machine will carry out the Gamma Automatic Adjustment after you change the maximum density. When the Gamma Automatic Adjustment is completed, proceed to the calibration with the Image controller.

  • When Integrated Color Care Unit IQ-501 or Relay Unit RU-518 is mounted, we recommend you to first perform Maximum Density Auto Adjustment.

  • Be sure to perform Color Density Manual Control after changing the maximum density.

This section describes how to make adjustments when this machine is equipped with Integrated Color Care Unit IQ-501 and Relay Unit RU-518.

  1. Press Adjustment on the MACHINE screen to display the Adjustment Menu screen.

  2. Press Quality Adjustment and Maximum Density Adjustment in sequence.

  3. Press Print Mode.

  4. Select the paper tray used for adjustment, then press Start on the control panel.

    A chart applied the Screen 1 (Dot190 Recommended) is Output.

    Charts are processed by colorimetry, and delivered to the output tray.

    When Integrated Color Care Unit IQ-501 and Relay Unit RU-518 are not mounted, print charts using the pre-specified paper, and measure the density using your spectrophotometer. Then, manually repeat adjustments until the target result is obtained. After adjustment, proceed to step 7.

  5. After outputting the charts, the screen returns to the Maximum Density Adjustment screen and the measurement result is displayed under Density Measurement Result (Rough Value) in the lower right of the screen.

    • supplementary explanationPress Measurement History to view the measurement history (up to 30 results).

    Press Switch Display on the Maximum Density Measurement History screen to change the items in the history list. (Display 1: Measurement Date and Measured Value for each color, Display 2: Paper Type and Set Value for each color.)

  6. Change the adjustment value for each color to suit the measurement result.

    • supplementary explanationThe measurement result is lower than the desired density.: Change the adjustment value to the positive (+) side.

    • supplementary explanationThe measurement result is higher than the desired density.: Change the adjustment value to the negative (-) side.

  7. Repeat steps 3 to 6 until the desired result is obtained.

  8. Press OK to complete the setting.

    • supplementary explanationTo cancel the change, press Cancel. In either case, the screen returns to the Quality Adjustment Menu screen.

    NOTICE

    • If you press Cancel, the maximum density measurement result is not saved.
