Pass/Fail Limits - Are individual limits set on each attribute of the
selected color space. In cases where the DE tolerance method is selected,
only one value is entered. The limits can be set from .01 to 9.99. The
limit for individual attributes can also be turned "Off" by advancing past
9.99.
Shade Sort Size - The shade sort size are dimensions placed on the color
space attributes. The value represents a three dimensional box in space.
These boxes are layered nine deep on each axis and at the center is the
555 reference box. This box represents your reference color. The value
in the L*, a*, and b* fields determine the reference box size. Enter a
smaller value for a tighter tolerance. Values range from .01 to 9.99.
Shade Sort Range - Determines the range of 555 shade tag boxes to be
used and displayed. The range can be set from 1 to 9 in the three
dimensional space.
