Elliptical Tolerance - Konica Minolta CR-400 Instruction Manual

Elliptical tolerance

This judges whether or not the value of the measured color difference is within the range of the ellip-
tical tolerance set for the color difference target color. When setting an elliptical tolerance, besides the
tolerance value, an offset and a rotation can also be set.
If the set color space is "L*C*h" the col or difference tolerance is set along the "L*a*b*" color space
axis, and if the set color space is "L99C99h99" then the "L99a99b99" color space axis is used.
See P.80 "Color Space and Color Difference Setting" for details.
Set a color difference target color ahead of time before setting an elliptical limit.
Since the color difference graphs are displayed in two dimensions, the fail judgment data may some-
times be displayed as plotted inside the tolerance in each graph.
Selecting the limit value in P.115 displays the [limit value] selection screen.
