Abstract:
1. An apparatus, comprising: a scanner comprising a plurality of sensors, each sensor configured to measure one or more characteristics associated with a different portion of a substrate, the substrate having printing produced by a printing system, wherein a location of at least one of the sensors is adjustable in relation to at least one other of the sensors to achieve optimal measurements for a particular printing; and a controller configured to receive at least some of the measurements from the plurality of sensors and to determine a quality of the printing on the substrate using the received measurements; wherein at least a first of the sensors is slidably mounted on a frame and attached to a guide, and at least a second of the sensors is fixably mounted on the frame; and wherein the apparatus further comprises a guide mover configured to move the guide so as to move at least the first sensor across part of a surface of the substrate.
