Abstract: Printing apparatuses for detection of substrate alignment, methods for manufacture and use thereof, and substrates are disclosed. One printing apparatus may include a printing assembly having at least one conductive alignment sensor with a plurality of inductive coils configured to generate an electromagnetic field. The printing assembly may receive at least one substrate having at least one conductive portion and align the substrate such that the plurality of inductive coils and the conductive portion substantially overlap with each other to form an electromagnetic field having a direction from the at least one conductive alignment sensor to the at least one conductive portion. The direction of the electromagnetic field with respect to the conductive alignment sensor may form an angle. The conductive alignment sensor may be configured to detect a movement of the conductive portion when a change to the angle causes a current change through the plurality of inductive coils.

Abstract: Methods and systems for detecting alignment of a substrate during a printing process are described. In an embodiment, a printing apparatus may comprise an apparatus polarization area. A substrate may be configured with a substrate polarization area. The substrate may be arranged on the printing apparatus during printing such that the substrate polarization area overlaps the apparatus polarization area to form an alignment area. During printing, light may be radiated onto the alignment area to generate polarized light. The polarized light may be received by a polarized light receiving device. Characteristics of the light received by the polarized light receiving device may be monitored for variations. The variations may indicate that the substrate is not properly aligned for printing on the printing apparatus.
