Tracking definitions
Before calculating the approximate tracking line speed for Flyer marking heads in a given application, sev-
eral terms must be defined. To obtain the highest possible line speed and mark quality, please review these
definitions carefully before designing your FH Flyer tracking application.
Mark
The Mark is the object, or collection of objects, defined by the bounding box when all marking objects are
selected in your WinMark Pro .mkh mark file.
Marking Window
The Marking Window is best explained by visualizing an area the size of WinMark Pro’s Drawing Canvas
centered on the center point of the factory test mark in the focal plane of the lens. The Drawing Canvas
would exactly cover the maximum Marking Window for the selected lens. For example, with a 200 mm FH
lens selected, the maximum Marking Window dimensions are 165 mm × 134 mm. When using a 125 mm
FH lens, the Marking Window spans a 105.6 mm × 85.7 mm ar ea.
Usable Field Size
Usable Field Size is the distance, in millimeters, from the downstream edge of Mark placement in the
Mark-ing Window to the downstream edge of the Marking Window in the axis of part motion. Figure 5 -2
