Maximum Density Adjustment: Adjusting the Maximum Density for Y, M, C, and K

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

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

  • 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-509 is mounted on the machine, we recommend you to first perform Max. Density Auto Adjustment.

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

This section describes how to perform the adjustment procedure when Integrated Color Care Unit IQ-501 or Relay Unit RU-509 is mounted on the machine.

  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].

    • When Integrated Color Care Unit IQ-501 and Relay Unit RU-509 are not installed on this machine, print out test charts on the pre-specified paper. Then, conduct measurement using your spectrophotometer, and repeat the manual adjustment until the target result is obtained. After adjustment, proceed to step 7.

  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.

    The charts are measured using the density sensor of Relay Unit RU-509 and delivered into the output tray.

  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.

    • Press [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.

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

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

  7. Repeat steps 3 to 5 until the desired result is obtained.

  8. Press [OK] to complete the setting.

    • To cancel the change, press [Cancel]. In either case, the screen returns to the [Quality Adjustment Menu] screen.

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