    • The invention concerns a procedure for controlling printing quality, wherein the digital presentation of the page original is utilized. As taught by the invention, prior to printing a plurality of measuring points are specified from the digital presentation of the page original on the basis of given initial data. The initial data for the measuring points are set so that at least two measuring points are locating points on the basis of which the other measuring points can be located. The other initial data are set according to what one desires to measure on the printed page. Thereafter, the locating points and other specified measuring points are sought in the digital presentation of the page original; and the measuring point data are entered in the printing quality measuring unit. The results of measurement from the measuring points are compared with the measuring point data from the digital presentation of the page original, or the objective values, and the results of comparison are used to adjust the printing machine.
    • 本发明涉及用于控制打印质量的程序,其中利用了页面原稿的数字呈现。 如本发明所教导的,在打印之前,根据给定的初始数据从页面原稿的数字呈现中指定多个测量点。 测量点的初始数据被设置为使得至少两个测量点是可以位于其他测量点的定位点。 其他初始数据根据打印页面上要测量的内容进行设置。 此后,在页面原稿的数字呈现中寻找定位点和其他指定的测量点; 并且测量点数据被输入到打印质量测量单元中。 将测量点的测量结果与来自页面原稿的数字显示或目标值的测量点数据进行比较,并且比较结果用于调整打印机。

    • A procedure and apparatus for analyzing wear particles present in a flowing fluid and for continuously determining the wear situation of mechanical contacts. The fluid is conducted to a point of examination in a measuring passage (2), stopped, and imaged there with a photoelectric detector (8). With a data processing device (13), the image in analog form is digitized, and from the image are, by methods of digital image processing, automatically determined the central index values in view of degree of purity and/or wear situation, which describe the size, size distribution, shape, surface structure, light transmittance and/or colour of the particles in the fluid. The information thus obtained is classified with the aid of the index values found and of a predetermined set of deduction rules, such as an expert system, and the wear situation of sliding and/or rolling mechanical contacts in contact with the fluid is determined.
    • 用于分析存在于流动流体中的磨损颗粒并用于连续地确定机械接触的磨损情况的步骤和装置。 将流体传导到测量通道(2)中的检查点,停止,并用光电检测器(8)在其上成像。 利用数据处理装置(13),模拟形式的图像被数字化,并且通过数字图像处理的方法从图像中自动地根据纯度和/或磨损情况确定中心指数值,其描述 流体中颗粒的尺寸,尺寸分布,形状,表面结构,透光率和/或颜色。 借助于所找到的指标值和专家系统等预定的扣除规则,确定所得到的信息,并确定与流体接触的滑动和/或滚动机械触点的磨损情况。
