    摘要： 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.

    摘要： An inkjet printer is described. The inkjet printer has a substrate holder assembly that includes a base member having a long axis in a first direction and a short axis in a second direction perpendicular to the first direction; a contact member coupled to the base member, the contact member having a long axis in the first direction and a short axis in the second direction; a holder carriage coupled to the base member; a linear extender coupled between the base member and the contact member and extending in a third direction intersecting with the first direction and the second direction from the base member toward the contact member; and a flex member coupled to the base member, extending in the second direction between the linear extender and the contact member, and having a flex direction in a direction perpendicular to the first direction and the second direction.

    摘要： The present teachings relate to various embodiments of a gas enclosure system that can have various components comprising a particle control system that can provide a low-particle zone proximal to a substrate. Various components of a particle control system can include a gas circulation and filtration system, a low-particle-generating motion system for moving a printhead assembly relative to a substrate, a service bundle housing exhaust system, and a printhead assembly exhaust system. In addition to maintaining substantially low levels for each species of various reactive species, including various reactive atmospheric gases, such as water vapor and oxygen, for various embodiments of a gas enclosure system that have a particle control system, an on-substrate particle specification can be readily met. Accordingly, processing of various substrates in an inert, low-particle gas environment according to systems and methods of the present teachings can have substantially lower manufacturing defects.

    摘要： The present teachings disclose various embodiments of a printing system for printing a substrate, in which the printing system can be housed in a gas enclosure, where the environment within the enclosure can be maintained as a controlled printing environment. A controlled environment of the present teachings can include control of the type of gas environment within the gas enclosure, the size and level particulate matter within the enclosure, control of the temperature within the enclosure and control of lighting. Various embodiments of a printing system of the present teachings can include a bulk ink delivery system that can be external to a gas enclosure. A bulk ink delivery system according to the present teachings can supply ink to a local ink delivery system that is internal to the gas enclosure. Various embodiments of a local ink delivery system of the present teachings can be proximal to a printhead device assembly, and can include a two-stage ink supply having a local ink replenishment reservoir that is configured to supply a local ink dispensing reservoir to a constant volume. According to the present teachings, a local ink dispensing reservoir can be in flow communication with a plurality of printhead devices. As such, a two-stage local ink delivery system maintaining a constant volume in a local ink dispensing reservoir can provide constant head pressure to the plurality of printhead devices.

    摘要： The present teachings disclose various embodiments of a printing system for printing a substrate, in which the printing system can be housed in a gas enclosure, where the environment within the enclosure can be maintained as a controlled printing environment. A controlled environment of the present teachings can include control of the type of gas environment within the gas enclosure, the size and level particulate matter within the enclosure, control of the temperature within the enclosure and control of lighting. Various embodiments of a printing system of the present teachings can include a Y-axis motion system and a Z-axis moving plate that are configured to substantially decrease excess thermal load within the enclosure by, for example, eliminating or substantially minimizing the use of conventional electric motors.
