NOTE: In addition to the values that you set in the Tracking menu, the
color CVIM system returns two additional values that reflect the Web
Movement parameter setting, as follows:
•
Lanes per field of view –– This is a value between 0 and 15 (decimal), and
it reflects the number of “lanes” in the blister layout. A “lane” is a group
of blisters lying along an axis that is parallel to the direction of web
movement in the image field.
•
Steps per field of view –– This is a value between 0 and 15 (decimal), and
it reflects the number of “steps” in the blister layout. A “step” is a group
of blisters lying along an axis that is perpendicular to the direction of web
movement in the image field.
Thus, if the direction of web movement in the image field is vertical, (and
the
Web Movement parameter is set to Vertical ), the system will regard a
column of blisters in the image field as a lane and a row of blisters as a step.
Conversely, if the direction of web movement in the image field is
horizontal, (and the
Web Movement parameter is set to Horizontal ), the
system will regard a row of blisters in the image field as a lane and a column
of blisters as a step.
