摘要： An actuator drive circuit of a liquid discharge apparatus includes a discharge waveform generating circuit, a sleep waveform generating circuit, and a wake waveform generating circuit. The discharge waveform generating circuit is configured to generate a plurality of drive waveforms to be applied to actuators of the liquid discharge apparatus for liquid discharge. The drive waveforms correspond to gradation values of gradation scale data. The sleep waveform generating circuit is configured to generate a sleep waveform to be applied to the actuators. The sleep waveform causes a voltage of the actuators to transition to a first voltage without liquid discharge. The wake waveform generating circuit is configured to generate a wake waveform to be applied to the actuators. The wake waveform causes the voltage of the actuators to transition to a second voltage higher than the first voltage without liquid discharge.

摘要： Large, overlapping "mega-dots", placed on small, high resolution pixel locations, are used in high quality monochrome imaging to preserve information to the micro, or pixel, level, thus avoiding the need to use micro-sized droplets. By using multiple passes and multiple pens with different levels of gray ink, one may build a single monochrome 600 dpi (dots per inch) pixel with the composite gray of those droplets at that pixel location as well as the neighboring locations. With careful print modes and multiple passes, one can produce several levels of gray at a particular pixel location. The biggest advantage of using multipixel dots is that the sensitivity to trajectory errors is significantly reduced. For example, a dot that is 1/150.sup.th inch diameter is almost indifferent to a 1/1200.sup.th trajectory error. Even a relatively large 1/600.sup.th inch error has little impact on the large 1/150.sup.th dot (25% error). In reducing the sensitivity to trajectory errors, overall imaging errors, such as banding, can be reduced, and overall image quality enhanced. Optimally, the large dots have a diameter that is about three to five times the pixel size, providing an overlap of three to five dots, respectively.
摘要翻译： 放置在小，高分辨率像素位置上的大的重叠“大点”被用于高质量的单色成像以将信息保存到微观或像素级，从而避免使用微尺寸液滴。 通过使用具有不同级别的灰色墨水的多遍和多笔，可以构建单个600dpi（每英寸点数）像素，其中该像素位置处的那些液滴的复合灰色以及相邻位置。 通过仔细的打印模式和多次通过，可以在特定像素位置产生多个灰度级别。 使用多像素点的最大优点是显着降低了对轨迹误差的敏感度。 例如，+ E，fra 1/150 + EE th英寸直径的点几乎与+ E，fra 1/1200 + EE轨迹误差无关。 即使相对较大的+ E，fra 1/600 + EE th英寸的误差对大的+ E，fra 1/150 + EE点（25％误差）几乎没有影响。 在降低对轨迹误差的敏感性方面，可以减少整体成像误差（如条带），并提高整体图像质量。 最佳地，大点的直径大约是像素尺寸的三到五倍，分别提供三到五个点的重叠。
