摘要： According to the present invention, multiple rows of nozzles within a print head may be arranged proximal to and offset from each other to facilitate inkjet printing. Print heads may comprise a single row of nozzles or may comprise a plurality of rows of nozzles. Each row of nozzles may be situated such that the immediately adjacent row of nozzles may be offset by a predetermined distance. In some embodiments, adjacent rows of nozzles may each print with the same color. In this way, adjacent offset rows of nozzles may be used in combination to dispense ink drops into sub-pixel wells in improved patterns and with improved ink distribution within the sub-pixel well. These offset print techniques may also enable tighter grouping of ink drops within a sub-pixel well and enable faster printing operations.
摘要翻译：根据本发明，打印头内的多排喷嘴可以布置成彼此靠近并且彼此偏离，以便于喷墨打印。打印头可以包括单排喷嘴，或者可以包括多排喷嘴。每排喷嘴可以被定位成使得紧邻的喷嘴排可以偏移预定距离。在一些实施例中，相邻排的喷嘴可以以相同的颜色打印。以这种方式，相邻的喷嘴排可以组合使用，以将墨滴以改进的图案分配到子像素阱中，并且改进子像素阱内的油墨分布。这些偏移打印技术还可以使得子像素内的墨滴更紧密地分组并且能够实现更快的打印操作。

摘要： The present invention provides methods and apparatus for controlling the quantity of fluid output (e.g., drop size) by individual nozzles of a print head to a very high precision at a frequency equal to the frequency at which fluid is normally dispensed. This is achieved by mapping fluid quantity control information into the data that represents the image to be printed. Data representative of an image is received and converted into pixel data. In at least one embodiment, the pixel data includes pixels represented by N bits, and the N bits may represent a drop size for the pixel and a union of the N bits may represent a nozzle status. A print head may be controlled based on the pixel data, and the print head may include nozzles that are each adapted to deposit at least one drop size quantity of a fluid on a substrate.

摘要： A cabinet for housing an ink supply is provided for use with an inkjet printing system. The cabinet, ink supply, and related structures are set apart from inkjet print heads in the inkjet printing system. Accordingly, the cabinet provides a location to store and supply quantities of ink and may make service and replacement of parts and/or consumables simpler and more accessible. The cabinet also houses components used to process and/or supply ink to inkjet print heads such as solvent, fluid delivery mechanisms (e.g., pumps, gas pressure devices, etc.), tubes, sensors, filters, exhaust, and drainage.
