1. An apparatus for producing and inspecting a plurality of features in a pattern on a surface of a substrate, comprising:

  • a printhead that deposits a fluid to form a plurality of features in a pattern on a first portion of a substrate surface, leaving a second intervening portion of the substrate surface nominally featureless;

    an image acquisition system that images the substrate surface, said image acquisition system comprising;

    a camera and a camera controller that positions and activates said camera to image in a two-dimensional manner by moving the camera across said first portion in a perpendicular direction with respect to a line of said features to acquire images corresponding to said first portion and less than all of said second portion; and

    a printhead controller that positions the printhead relative to the substrate surface and activates the printhead to sequentially deposit the plurality of features in the pattern.
