Abstract:
A device for applying fiducial marks to a web for spatially synchronizing data from a plurality of processes is described. The device includes a fiducial mark reader to read fiducial marks of at least two formats on a web of material, a fiducial mark writer to write fiducial marks of at least two formats on the web, and an encoder to measure distance along the web. The device may provide several advantages. For example, the device may apply fiducial marks to a web that indicate the process line that applied the fiducial mark to the web or the date on which the fiducial mark was applied.
