摘要： Digital ink jet printing apparatus and method. The apparatus receives an input image file having a plurality of pixels, each pixel described by at least one pixel value respectively associated with an optical density. The apparatus comprises a printhead (50) and at least one nozzle (45) integrally attached to the printhead, the nozzle being capable of ejecting an ink droplet (47) therefrom to define an associated one of the optical densities. A waveform generator (230) is connected to the nozzle for generating an electronic waveform (80) to be supplied to the nozzle. In this manner, the nozzle ejects the ink droplet in response to the waveform supplied thereto. The waveform is defined by a plurality of pulses (90). A look-up table (60) stores a plurality of waveform serial numbers assigned to respective waveforms, each waveform being defined by at least one predetermined parameter, such as number of pulses, pulse amplitude, pulse width and/or time delay between pulses. A calibrator receiving the input image converts the pixel values of the input image to waveform index number associated with the waveform serial number.
摘要翻译： 数字喷墨打印设备及方法。 该装置接收具有多个像素的输入图像文件，每个像素由分别与光密度相关联的至少一个像素值描述。 该设备包括打印头（50）和与打印头整体连接的至少一个喷嘴（45），该喷嘴能够从其喷射墨滴（47）以限定相关联的一个光密度。 波形发生器（230）连接到喷嘴，用于产生供给喷嘴的电子波形（80）。 以这种方式，喷嘴响应于供给的波形喷射墨滴。 波形由多个脉冲（90）限定。 查找表（60）存储分配给各个波形的多个波形序列号，每个波形由至少一个预定参数（例如脉冲数，脉冲幅度，脉冲宽度和/或脉冲之间的时间延迟）来定义。 接收输入图像的校准器将输入图像的像素值转换成与波形序列号相关联的波形索引号。
