ColorFlex EZ User's Manual Version 2.2
Figure 21. Physical Standard
Choose NUMERIC when a physical specimen does not exist for measurement, but the target
color values are known from previous measurements. The color values for a numeric standard
are entered and stored in the product setup for as long as desired.
Figure 22. Numeric Standard
Choose HITCH for agreement between two or more instruments. This is helpful when
companies are manufacturing the same product in different plants and need the colors to
match. A standard is measured on a reference instrument and the color values noted. This
Hitch standard is then read on a second instrument such as the ColorFlex EZ and the target
values from the reference instrument are entered manually. The ColorFlex EZ then
mathematically adjusts to match the reference instrument. The modified standard is stored in
the product setup for as long as desired.
