HOW TO MEASURE THE SPECTRUM OF A COLOR USING AN Eye-One AND Measure Tool

(last edit: 23 November 2004)

First, to generate spectral data, you need the Eye-One spectrophotometer,
not the Display model.

A spectrophotometer shows how reflective is each patch at given colors
across the visible spectrum. The Display model is a colorimeter, and
gives only the color coordinates (i.e. L*a*b*, which is enough for many
tasks but not this one).

Procedure:

Preset: select the Tool/Configure Instrument menu and check the spectrum box.
From there-on, your measured files should contain a spectra.

Procedure:

1- Click on the Measure/Test page (large) icon

2- Select a custom TestChart size (24 zones, 4 zones per band)

3- Click to launch the measure

4- Select the Zone mode

5- Using the Eye-One, measure each patch using the provided plastic guide
(the elliptically shaped one).

  Suggestion: start at the upper-left (dark-skin), then go by rows.

  Be careful not to slide the plastic instruments on your chart and ruin
  your chart.


6- When a chart is done, select "Save As" .txt format.
