  • Patent number: 10994557
    Abstract: A printing apparatus includes a feeding unit, a pair of rollers, a printing unit, and a control unit. The control unit can execute skew correction. The control unit can execute control to convey a preceding printing medium and a succeeding printing medium by the pair of rollers in a state in which a trailing edge portion of the preceding printing medium and a leading edge portion of the succeeding printing medium overlap. The control unit sets an execution timing of the skew correction for the succeeding printing medium based on positions of the preceding printing medium and the succeeding printing medium if a predetermined condition is met. The predetermined condition is that the preceding printing medium reaches a position at which a remaining print range for the preceding printing medium equals a predetermined print range.

  • Patent number: 10996560
    Abstract: Reducing an alignment error of an imprint lithography template with respect to a substrate includes locating central alignment marks of the template with respect to corresponding central alignment marks of the substrate and locating peripheral alignment marks of the template with respect to corresponding peripheral alignment marks of the substrate. In-plane alignment error of the template is assessed based on relative positions of central alignment marks of the template and corresponding central alignment marks of the substrate. A combined alignment error of the template is assessed based on relative positions of peripheral alignment marks of the template and corresponding peripheral alignment marks of the substrate. Out-of-plane alignment error of the template is assessed based on a difference between the-combined and the in-plane alignment error of the template, and a relative position of the template and the substrate is adjusted to reduce the out-of-plane alignment error of the template.
