Abstract: A method for printing a substrate may comprise positioning a substrate within an enclosure enclosing a printing system, wherein the printing system comprises a printhead device assembly comprising at least one printhead, and performing a printing process on the substrate. and. The printing process may comprise supplying ink from a local ink dispensing reservoir to the printhead device assembly, the local ink dispensing reservoir located inside the enclosure; supplying ink from a local ink replenishment reservoir to the local ink dispensing reservoir so as to maintain, in the local ink dispensing reservoir, a level of ink within a first predetermined range, the local ink dispensing reservoir located inside the enclosure; supplying ink from a bulk ink delivery system, through a fluid line disposed inside an outer conduit, and to the local ink replenishment reservoir so as to maintain, in the local ink replenishment reservoir, a level of ink within a second predetermined range, the bulk ink delivery system located outside the enclosure; and depositing ink from the at least one printhead on the substrate

Abstract: 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.

Abstract translation: 本教导公开了用于印刷衬底的打印系统的各种实施例，其中打印系统可以容纳在气体外壳中，其中外壳内的环境可以被保持为受控打印环境。 本教导的受控环境可以包括控制气体外壳内的气体环境类型，外壳内的尺寸和级别的颗粒物质，控制外壳内的温度和控制照明。 本教导的打印系统的各种实施例可以包括可以在气体外壳外部的散装墨水输送系统。 根据本教导的散装墨水输送系统可以向位于气体外壳内部的局部墨水输送系统供应墨水。 本教导的本地墨水输送系统的各种实施例可以靠近打印头装置组件，并且可以包括具有局部墨水补充储存器的两级墨水供应器，其被配置为将局部墨水分配容器供应到恒定体积 。 根据本教导，本地墨水分配储存器可以与多个打印头装置流体连通。 因此，在局部墨水分配储存器中保持恒定体积的两级局部墨水输送系统可以向多个打印头装置提供恒定的头部压力。
