Example implementations relate to determining a correction factor that converts a measured sensor distance to a calibrated sensor distance. The measured sensor distance may be based on an amount of substrate advancement through a web printing press between detecting a mark on the substrate at a first sensor and detecting the mark at a second sensor. The calibrated sensor distance may be the separation between the first sensor and the second sensor.

Measured sensor distance correction

There is disclosed a web transfer apparatus including a web transfer roller to advance a web, a foil transfer roller to advance a foil, and a movable curing unit. The foil transfer roller is movable between a first position and a second position. In the first position, the foil transfer roller is to press the foil against the web and in the second position the foil transfer roller is to disengage the foil from the web. The movable curing unit may comprise a curing device and may be movable between a first position adjacent to the web and a second position remote from the web.

Example implementations relate to determining a correction factor that converts a measured sensor distance () to a calibrated sensor distance (). The measured sensor distance may be based on an amount of substrate advancement through a web printing press () between detecting a mark (--N) on the substrate () at a first sensor () and detecting the mark at a second sensor (). The calibrated sensor distance () may be the separation between the first sensor and the second sensor.
