Measuring color with the EFI ED-100
This section describes the basics of taking measurements with the EFI ED-100. Once you
have mastered this technique, see the section “Calibrating with ColorWise Pro Tools using
the EFI ED-100” to properly calibrate your copier.
Guidelines for taking color measurements
Keep in mind the following when using the EFI ED-100 to take measurements:
• Ensure the page you are measuring rests on a flat, firm surface.
• Make sure the measurement page does not rest on an intensely colored surface. For more
accurate measurement, place blank sheets of the same kind of paper as the measurement
page beneath it to block underlying colors from being read by the EFI ED-100.
• Do not touch the patches with your fingers.
• Verify that the aperture is centered over the color patch. Use the aiming guide lines to
help you.
• Ensure the EFI ED-100 is pressed against the patch you are measuring.
• Hold the EFI ED-100 at a right angle to measure a row of patches and make sure that it
remains perpendicular to the sample row during measurement. This is to ensure that
contact is confined to the patch being measured.

USING
THE
EFI ED-100
N
OTE
:
Software that supports the EFI Densitometer ED-100 (for example, ColorWise Pro
Tools Calibrator
™
) provides the patch pages that you print and measure with the
EFI ED-100.
1. Place the EFI ED-100 over a sample patch so that the sample aperture on the bottom of the
EFI ED-100 completely covers the sample patch.
The aiming guidelines on the tip of the EFI ED-100 indicate where the sample aperture is
located. The busy indicator light is centered directly above the sample aperture.

:
For more accurate measurement, place a sheet of white paper beneath the sample
patch to block underlying colors from being read by the EFI ED-100.
2. Press the green button (Go) to initiate the measurement process.

:
You do not have to hold the button down during the measurement. Typical
measurement time is approximately one second.
When the busy indicator light turns off, the measurement is complete and you can move to
the next sample to take a new measurement.
Calibrating with ColorWise Pro Tools using the EFI ED-100
Using ColorWise Pro Tools Calibrator and the EFI ED-100, you can quickly measure color
patches generated by the copier and download these measurements to the Fiery server.
N
OTE
:
Multiple users can be connected to one Fiery with ColorWise Pro Tools, but only
one user at a time can use Calibrator. An error message appears if you try to calibrate when
another user is already using ColorWise Pro Tools to calibrate.
