Measuring the density balance using a spectrophotometer

To measure the chart, use the X-rite Measure tool. Install the tool in advance.

  • You can download the X-rite Measure tool free of charge at the following Web site. After installing the tool, restart the computer.
    ProfileMaker 5 v5.0.10:
    http://www.xrite.com

  • To use the spectrophotometer i1iSis, perform Step 10 (select [Measure] from the menu) followed by the procedure of "• For the spectrophotometer i1iSis."

  1. On the touch panel of the main body, press [Adjustment] on the [MACHINE] screen.

    The [Adjustment Menu] is displayed.

  2. Press [Density Balance Adjustment] on the [Adjustment Menu] screen.

  3. Press [Density Balance Chart Output].

  4. Select the chart to be output according to the spectrophotometer (i1iSis/i1Pro) to be used.

    After the selection, press [Print Mode].

    The [Type-1] of [<Measure Spectrophotometer-1 (i1-iSis)>], the [Type-2] of [<Measure Spectrophotometer-2 (i1-Pro)>], or the [Type-3] of [<Measure Spectrophotometer-3 (FD-5 BT)>] is recommended.

  5. Set the paper on the [PRINT MODE] screen and press Start on the control panel.

    The color chart is output for measurement using the spectrophotometer.

  6. On the computer where the X-rite Measure tool has been installed, select [Start] - [All Programs] - [X-Rite] - [ProfileMaker Pro 5.0.10] - [MeasureTool].

    X-rite Measure tool starts.

    • The following description uses screen examples in English. To change the display language for the menu and messages, select the language from [Language] on the Measure Tool toolbar, and then restart the X-rite Measure tool.

  7. When the following message is displayed, click [OK].

  8. Connect the instrument to the computer. From the menu, click [Configuring].

    The [Instrument Configuration] screen is displayed.

  9. In [Instrument], select the spectrophotometer to use. When [OK] is displayed, close the screen.

    Example: This example selects [Eye-One Pro] (i1Pro).

  10. From the menu, click [Measuring].

    • The subsequent operations are described for the case where the spectrophotometer i1Pro is used. For measurement using the spectrophotometer i1iSis, refer to "• For the spectrophotometer i1Sis."

  11. From [Test Chart], select [Custom].

  12. Specify [Columns] and [Rows], and click [OK].

    • When the spectrophotometer is "Type 1" of i1Pro: [Columns] = 6, [Rows] = 5

    • When the spectrophotometer is "Type 2" of i1Pro: [Columns] = 6, [Rows] = 13

  13. Click [Start].

  14. When the following message is displayed, horizontally place the spectrophotometer on the calibration dock and click [OK].

  15. Stack 10 sheets of blank paper whose type is the same as that of the paper where chart has been printed, and place the printed chart on top of it.
