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 28. Numeric Standard 

Choose 

HITCH

 for agreement between two or more instruments and 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 placed on a second instrument such as the ColorFlex EZ Citrus. This Hitch 
Standard is then read on the ColorFlex EZ Citrus and the target values from the reference 
instrument entered manually. The ColorFlex EZ Citrus then mathematically adjusts to match the 
reference instrument. The modified standard is stored in the product setup for as long as 
desired.
