Defining Standard, Sample and Tolerances
Product Standard
A product standard is an object that represents the ideal target color for the product. This
object is the one to which others will be compared and deemed acceptable or unacceptable.
The product standard may either be a physical item that is measured using the ColorFlex EZ
Citrus or a set of color values that is entered into the ColorFlex EZ Citrus
’s memory.
Sample
A sample is an object that will be measured with the ColorFlex EZ Citrus and compared to the
product standard. The color of the sample is generally similar to the color of the product
standard.
Tolerances
Tolerances are limits that indicate how different a sample can be from the product standard
and still be acceptable. Positive and negative tolerances may be set for each color scale and
index parameter chosen for display. Then, the ColorFlex EZ Citrus can show a pass or fail
indicator after a sample is read.
Samples that differ from the standard by no more than the entered tolerance are said to pass.
Samples that exceed the tolerance for one or more parameter are said to fail.
