摘要： An ink-jet printhead having a thin film substrate, the substrate including a plurality of thin film layers including a gold thin film layer overlying a tantalum thin film layer, an underlying passivation layer and an aluminum thin film layer underlying the passivation layer. A portion of the substrate is disposed adjacent an outer edge thereof and an ink barrier layer overlies the thin film substrate, the barrier layer having a first edge. The substrate portion extends beyond the barrier layer first edge. A plurality of bond pads is disposed on the substrate portion. Power and ground traces are coupled to a respective bond pad and are dropped through vias in the substrate portion to the thin film aluminum layer underlying the passivation layer. The traces are returned through vias to the gold thin film layer at a location separated from the barrier first edge. The gold and tantalum material between the vias is removed thereby providing a region in the printhead wherein the barrier layer directly adheres to the passivation layer.

摘要： Disclosed is an inkjet print cartridge including an ink supply, a substrate having a plurality of individual ink ejection chambers defined by a barrier layer formed on a first surface of the substrate and having an ink ejection element in each of the ink ejection chambers, for ejecting drops of ink having a predetermined drop volume and drop velocity. The ink ejection chambers each have the same inlet channel length and are arranged in an array spaced so as to provide a predetermined resolution. A nozzle member having a plurality of ink orifices formed therein is positioned to overlie the barrier layer with the orifices aligned with the ink ejection chambers. An ink channel connects the reservoir with the ink ejection chambers. The inkjet print cartridge has several advantages of over previous printing systems in creating high quality images by using very small individual ink drops of low volume and high velocity. Highlight regions may be formed by using single low volume drops to form a dot. The individual drops are nearly invisible and can be used to form highlights with low graininess. As the density of the image increases, multi-drop dots are formed from two or more drops merging on the media to form a composite drop.
摘要翻译：本发明公开了一种喷墨打印墨盒，包括墨水供应源，具有由形成在基板的第一表面上的阻挡层限定的多个单独的喷墨室的基板，并且在每个喷墨室中具有喷墨元件，用于喷射具有预定液滴体积和液滴速度的墨滴。喷墨室各自具有相同的入口通道长度并且排列成间隔开的阵列，以便提供预定的分辨率。具有形成在其中的多个墨孔的喷嘴构件定位成覆盖阻挡层，孔与墨喷射室对准。墨水通道将储存器与喷墨室连接。喷墨打印墨盒具有超过以前的打印系统的几个优点，通过使用低体积和高速度的非常小的单个墨滴来产生高质量的图像。可以通过使用单个低体积滴形成点来形成突出区域。单个滴几乎看不见，可用于形成低颗粒度的亮点。随着图像的浓度增加，在介质上合并两个或多个墨滴形成多点滴以形成复合液滴。

摘要： An inkjet print cartridge includes an ink supply and a substrate having a plurality of individual ink ejection chambers defined by a barrier layer formed on a first surface of the substrate and having an ink ejection element in each of the ink ejection chambers to eject ink drops. A nozzle having a plurality of ink orifices formed therein overlies the barrier layer with the orifices aligned and associated with the ink ejection chambers. An ink channel connects an ink supply. A group of the ink ejection chambers in adjacent relationship forms a primitive in which a maximum of only one ejection chamber in the primitive is energized at a time and the primitive is one of a plurality of primitives on the substrate. A first circuit on the substrate is connected to the ink ejection elements and a second circuit on the print cartridge is connected to the first circuit to transmit ejection signals to the ink ejection elements at high frequency. The first circuit applies primitive select signals to select one or more of the primitives and applies address line select signals to enable devices associated with the ink ejection elements in one or more of the selected primitives such that a maximum of one ink ejection chamber in a selected primitive is activated at a time.

摘要： An inkjet nozzle includes an aperture with a noncircular opening substantially defined by a polynomial equation. A droplet generator is also described which includes a firing chamber fluidically coupled to a fluid reservoir, a heating resistor and a nozzle. The nozzle includes an aperture forming a passage from the firing chamber to the exterior of the droplet generator through a top hat layer. The nozzle is defined by a closed polynomial and has a mathematically smooth and mathematically continuous shape around aperture's perimeter wall, with two protrusions extending into the center of the aperture.

摘要： An inkjet printhead assembly includes at least one inkjet printhead including N primitives and an address having M possible address values. Each primitive includes a group of at most M drop generators. The address is cycled through all M address values to control a sequence of which one drop generator in the primitive is fired at a given time. One drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives. A primitive to address ratio (N/M) of the printhead is at least 10 to 1.
