摘要：本发明的实施例提供3D打印设备及其成像系统，该成像系统包括：具有多个像素的显示面板，存储液态可光固化材料的存储装置，控制显示面板成像的控制装置；其中可光固化材料显示面板为主动式发光面板。该成像系统无需偏振片，以避免偏振片吸收光源系统发射的光；另一方面，由于没有背光，而是直接地利用显示面板发出的光形成图像投影，因此光路缩短，降低光损耗，从而提升了光的利用率，降低了整个系统的功耗。

摘要： A copier or a printer (10) includes a controller 16/30 with a rendering algorithm that groups sets of adjacent pixels into sets of adjacent cells where each cell corresponds to a halftone dot of an image. The algorithm operates in conjunction with a gray scale printhead (22). In sending data to the printhead, the controller (16) parses a scanned image and set the exposure for each pixel in accordance with a growth and density program. The algorithm selectively grows halftone dots from zero size to a desired size equal to or less than a maximum size. It repeats this step for the rest of the pixels until the cell is at its desired size and at an initial density. If a higher density is desired, the algorithm selectively adjusts the fully grown cells by sequentially increasing the level of exposure of each pixel in the cell. The image is developed with developer including a hard magnetic carrier and toner.
摘要翻译：复印机或打印机（10）包括具有渲染算法的控制器16/30，其将相邻像素的集合分组成相邻单元的集合，其中每个单元对应于图像的半色调点。该算法与灰度打印头（22）一起操作。在向打印头发送数据时，控制器（16）根据增长和密度程序解析扫描图像并设置每个像素的曝光。该算法将半色调点从零大小选择性地增长到等于或小于最大尺寸的期望大小。对于剩余的像素重复此步骤，直到单元格处于其所需的大小和初始密度。如果需要更高的密度，则算法通过依次增加单元中每个像素的曝光程度来选择性地调整完全生长的单元。图像用显影剂显影，包括硬磁性载体和调色剂。

摘要： Clock sources driving piezoelectric crystals are synchronised by a method and system in which target adapter boards (TABs 20a-20d) and fiber optic links (30, 32, 34a-34c) couple together plural printheads (12a-12d) in a daisy-chain configuration; an encoder device (35) of a controller (10) embeds a first clock signal in data and transmits the data to the printheads on the daisy-chain; a clock generating circuit of each TAB derives a second clock signal from the data, which is directly proportional to the first clock signal; and each printhead drives its corresponding piezoelectric crystal with the second clock signal. Time taken for data to propagate to each printhead is determined and the controller adjusts the phase of each second clock signal to reflect the propagation time by setting a preload register to a setting directly proportional to the position of a corresponding printhead in the chain.

摘要： A method of multi-tone printing employs a drop-on-demand printing apparatus (100) for depositing ink droplets from an array of channels (104) on printing element areas of a substrate (111) which is movable relatively to said apparatus. The channels' length and nozzle location and dimensions afford each channel with a high longitudinal resonant frequency and electrically actuable means (110, 112, 114, 116, 118) supply energy pulses to a selected band of channels at or near the resonant frequency of the channels to deposit from each selected channel in the corresponding printing element area of the substrate a number of drops equal to the number of pulses applied thereto, the number of pulses applied being dependent on the tone of printing required. Droplet ejection from even numbered channels is in anti-phase at the resonant frequency with droplet ejection from odd numbered channels.

摘要： An improved thermal printer has circuits that are responsive to selected parameters of the printer and to the contents (text/image data) of a document to be printed to selectively enable the individual printing electrodes with printing impulses of varying energy depending upon when the electrode had printed. Other circuits cause the selective process to be responsive to whether electrodes adjacent a selected electrode had printed and how recently such printing took place. In different embodiments, circuits utilize not only the history of a selected electrode and its neighbors, the as yet unprinted portion of the document to be printed is utilized to aid in the selection of an appropriate printing impulse.

摘要： A binary architectured LED printhead (25, 125) is driven in accordance with a multiple addressable, i.e., multiple sublines of recording, scheme to record grey level pixels. Respective sublines are recorded using a series of pulses that form a set of binary-weighted exposure strobe durations. Exposure durations for recording successive strobed sublines with a particular LED (20, 120) are ordered so that larger duration strobe pulses are followed by shorter duration strobe pulses. A plurality of strobe enable lines are provided to which respective recording elements are connected. A pulse from this set is generated during a subline exposure period on each enable line with each enable line having a pulse generated thereon that is of a different duration than that generated on the other enabling lines during the subline recording period and wherein during a subline exposure period the respective pulses on the enabling lines are substantially nonconcurrent. In one embodiment a series of data bits are formatted for presentation to the printhead (125) by a retransmit line buffer (206, 208) which transmits n times the data of one line of grey level pixels represented by n bits each to a process correction look-up table (220, 222). Another look-up table (216, 218) provides a signal to the process look-up table as to the intensity characteristics of the particular LED which is to print the pixel. The corrected grey level data is then input to a multiplexer (228, 230) which selects one of the n bits for printing in accordance with count signals related to the binary weight of the recording clock pulses.

摘要： A thermal printer is disclosed which is adapted to form an image on a thermal print medium of a type in which a donor element transfers dye to a receiver element upon receipt of a sufficient amount of thermal energy. The printer includes a plurality of diode lasers (36) which can be individually modulated to supply energy to selected dots on the medium in accordance with an information signal. The print head (20) of the printer includes a fiber optic array (30) having a plurality of optical fibers (31) coupled to the diode lasers (36). The thermal print medium is supported on a rotatable drum (12), and the fiber optic array (30) is movable relative to the drum. In order to prevent banding in an image produced on the print medium, the two outside fibers in the array are used for preheating and postheating of inner scan lines.
