Measuring the density balance using a spectrophotometer

To measure the chart, use the X-rite Measure tool (for the spectrophotometer i1iSis or i1Pro) or Color Care measure (for the spectrophotometer FD-5 BT). 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."

  • To use the spectrophotometer FD-5 BT, perform Step 5 (output the color chart) followed by the procedure of "• For the spectrophotometer FD-5 BT."

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

    The [Adjustment Menu] is displayed.
