DENSITY DIFFERENCE MEASUREMENT
Density difference measurement uses the same parameters as density
measurement. To set up for density difference measurement, follow
the procedures earlier in this chapter for selecting density function,
mode, and color measurement method.
To view measurement data as a density difference value between a
measured sample and a known referenceinstead of the density
value of the measured sampleyou must first enter a reference
measurement; and then activate the density difference (DEN-R)
display format.
Entering a Reference Measurement
1. Press FUNCTION until DEN appears in the display. After a
moment, a value for one a previous measurement appears in the
display.
2. Press ZERO. REF appears for a moment, followed by the
current Reference value. If none has been entered, the Reference
value is 0.00.
3. To enter a reference valueor change the current reference
valueyou can either:
measure the reference value directly; or
manually enter the reference value using the arrow button
functions.
To measure the reference value directly:
Measure the color that you wish to use as the reference. Then,
press FUNCTION to return to normal operation.
To enter the reference value manually:
Hold down the ZERO (ts) button, then press the
FUNCTION (t) or CAL (s)button to adjust the value until the
desired value is shown. Then, press FUNCTION to return to
normal operation.
TIP: If you need to move the value up or down by a large
amount, hold the arrow button down. The numbers will advance
faster as you hold it down.
4. Measure patch that is to be compared. DEN X is displayed
during measurement, where X is the installed optics.
