摘要： A method and apparatus are disclosed for a two-dimensional Moiré type absolute position encoder and an associated control system. A reticle having a pattern variation in two orthogonal directions is illuminated with radiation from a source which is structured so as to create a two dimensional Moiré interference at the reticle. Radiation pulses from the radiation source are multiplexed in time and the resulting interference fringes are converted into electronic signals using a detector. A controller uses the electrical signals to determine the absolute position of the reticle in two dimensions to within the area of a particular cell. After determining the particular cell location, the controller also employs the signals from the groups of radiation stripes to calculate an accurate position of the reticle within the cell.

摘要： A multirow multinozzle continuous inkjet head comprises a plurality of rows of inkjet nozzles ejecting drops in regions of airflow velocity within a collinear flow of air. The airflow velocity at all nozzles is equal, but lower than the highest airflow velocity within the collinear flow of air. This allows many more drop streams to be placed in a velocity-matched airstream. Despite the drops being in regions with air velocity gradients across the drops, the lateral forces are such that droplet placement on the print media surface is accurate and well controlled.

摘要： A continuous inkjet device emits a stream of fluid from nozzles. Droplet break-off is stimulated by the application of external perturbing stimulus to the stream in a manner that controls the formation of satellite drops. Satellite behavior is controlled by the use of a composite perturbing signal, composed of at least two frequencies that are not harmonically related, but are related by the ratio of small integers. In one embodiment, the use of two perturbing signals with frequencies fL and fH having a ratio of M/N, where M and N are integers, and M is not a multiple of N, and N is not a multiple of M, produces a repeating drop pattern of either M or N drops at the beat frequency of the combined signal, the constituent drops in said repeating pattern have different satellite formation characteristics. With suitable choice of phase and amplitude of the two component perturbing signals, at least one drop in the repeating pattern is observed to have favorable satellite behavior, or the absence of satellites, and is optimal for printing. This stimulation method, producing a repeating pattern of drops of different satellite behavior may then be aligned with the phase of a guard drop scheme, in which selected drops in a sequence are purposely charged and guttered in order to specifically reduce electrostatic crosstalk on print-selectable drops. By aligning the phase of the optimal printing drops of the stimulation means with the print-selectable drops of the guard drop scheme, all droplets with sub-optimal satellite behavior are thereby guttered and droplets with optimal satellite behavior are available for printing with great accuracy.
摘要翻译：连续的喷墨装置从喷嘴发出流体流。通过以控制卫星滴的形成的方式对流进行外部扰动刺激来刺激液滴分解。卫星行为由使用复合干扰信号控制，由至少两个不是谐波相关的频率组成，但与小整数的比率有关。在一个实施例中，使用具有M / N比的M / N的频率f 2和f H 2的两个扰动信号，其中M和N是整数，M不是 N的倍数，N不是M的倍数，在组合信号的节拍频率处产生M或N个下降的重复丢弃模式，所述重复模式中的成分丢弃具有不同的卫星形成特性。通过适当选择两个分量扰动信号的相位和幅度，观察到重复图案中的至少一个下降具有有利的卫星行为或不存在卫星，并且对于打印是最佳的。然后产生不同卫星行为的滴的重复图案的该刺激方法可以与保护液滴方案的相位对准，其中序列中的选定液滴被有意识地充电和排出，以便特别地减少打印可选择的静电串扰滴。通过将刺激装置的最佳打印液滴的相位与保护液滴方案的打印可选滴相对，由此排出具有次优卫星行为的所有液滴，并且具有最佳卫星行为的液滴可用于以高精度进行打印。

摘要： Methods and apparatus for determining the optimal adjustment of imaging systems used to prepare lithographic printing surfaces for a printing press are described. A series of test patterns are imaged while varying a particular imaging parameter. This is followed, if necessary, by processing the plate in processing line. The plate is then returned to the digital imaging system where the reflectivity of the imaged test patterns is measured using a radiation source and detector, to determine the optimal setting for the parameter.
