    Abstract: A printing system includes a substrate support, a printhead assembly positioned facing the substrate support, and an imager. The printhead assembly includes a plurality of dispensing nozzles extending in an ejection direction towards the substrate support and a plurality of marks. The imager is movable relative to the printhead assembly and oriented in a direction opposite to the ejection direction for capturing at least one image including the plurality of marks indicating positions of the plurality of dispensing nozzles in the printhead assembly.

    Abstract: In a printing method, at least one image of a substrate supported in a printing system is acquired. An actual position of a first alignment feature on the substrate in a frame of reference of the printing system is determined based on the at least one image. Expected positions of second alignment features on the substrate are determined based on the actual position of the first alignment feature. Actual positions of the second alignment features in the frame of reference of the printing system are determined based on the at least one image and the expected positions of the second alignment features. Target positions of print regions on the substrate are determined based on the actual positions of the second alignment features. Ejection of print material onto the substrate in the print regions is controlled based on the target positions of the print regions.

    Abstract: An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.

    Abstract: Methods of controlling an inkjet printer are disclosed. The methods include defining shape information using a design graphics system. The shape information includes fill colors for shapes, and may include colors for edges. The colors are interpreted as one or more attributes, such as film thickness or material, for a film to be formed on a substrate.
