Abstract
A tape is controlled in a printing machine by advancing a length of tape through a light pathway. Transmittance of the light through the tape is measured and values are stored associated with transmittances through the tape. The tape is advanced to a start position where measured transmittance of the tape at the start position corresponds with a stored value of a measured transmittance.
