The present invention provides a method of registering to an imaging web moving within an imaging web handling apparatus along an imaging web path. The imaging web comprises a support having a coating of photosensitive microcapsules on the surface thereof. The photosensitive microcapsules have an internal phase of a photosensitive composition and a color former. Exposure of the imaging web to actinic radiation defines an image area and a border area. A registration mark is formed on the web by exposing a portion of the web area to actinic radiation so that the portion undergoes a color or reflection change, or exposing all but a portion of the border area to actinic radiation so that the exposed area undergoes a color or reflection change. The registration mark is detected and in response to detection of the registration mark, an operation is performed on the imaging web.
