    • A machine for scanning printing plates to determine the ratio of "printing" to "non-printing" area for pre-adjustment of the ink dosing elements of a printing machine has an array of electronic photo-sensors, each sensor being disposed in a channel having low-reflection chambers which permit sharp delimination of resolution elements on the printing plate and ensure high definition scanning of different types of printing plates under practical conditions. Preferably the diaphragms dividing the channel into chambers have greater spacing at greater distances from the element sensed on the printing plate. To accommodate printing plates of different materials, means are provided for selecting the wave length of the light source. To prevent measurement error due to changes in the distance from the printing plate to the light source and sensor array, the photosensor array is preferably directed or aimed 60.degree. to 45.degree. with respect to the normal vector of the printing plate, and the light source is in the same quadrant as the photo-sensor array at an angle of 0.degree. to 45.degree. with respect to the normal vector. Automatic calibration, automatic printing plate size determination, automatic sensing of identification information engraved on the printing plate, and a stairstep scan to increase the scanning rate are provided by suitable procedures executed by a microcomputer controlling the scanning process and analyzing, adjusting, and interpreting data received from the sensor array.
    • 用于扫描印版以确定“印刷”与“非印刷”区域的比例的机器用于预先调整印刷机的墨水计量元件的阵列具有电子光电传感器阵列,每个传感器设置在通道中 具有低反射室,其允许印刷板上的分辨率元件的清晰划分,并且确保在实际条件下对不同类型印刷版的高清晰度扫描。 优选地,将通道分成腔室的隔膜在距离印刷板上感测的元件更远的距离处具有更大的间隔。 为了适应不同材料的印版,提供了用于选择光源的波长的装置。 为了防止由于从印版到光源和传感器阵列的距离变化而引起的测量误差,光传感器阵列优选地相对于印版的法向量指向或瞄准60°至45°,光源 与光电传感器阵列相对于法向量以0°至45°的角度位于同一象限内。 通过自动校准,自动印版尺寸确定,刻印在印版上的识别信息的自动识别以及增加扫描速度的平面扫描,由控制扫描过程的微机执行的合适程序提供,并分析,调整和解释数据 从传感器阵列接收。

    • An ink fountain for a printing press has a temperature-responsive element for compensating the adjustment of the spacing between the blade and the fountain roller to keep the thickness of the ink film fed by the blade substantially constant even under extreme temperature variations. The sub-frame of the ink fountain is pivotally mounted to the main frame of the printing press about a pivot axis generally parallel to the axis of the fountain roller, and the pivot angle is a function of the thermal expansion of the temperature-responsive element. In one preferred embodiment, the temperature-responsive element is elongated, received in a guide fixed to the sub-frame, and has a free end bearing against the bearing bushing of the fountain roller. In another embodiment, the temperature-responsive element is a side wall of the ink trough or is a plate parallel to the side wall of the ink trough, and rollers are journaled to the temperature-responsive element and bear against the surface of the fountain roller. In either embodiment, the temperature-responsive element is pre-stressed by a pull rod tending to pivot the sub-frame so that the temperature-responsive element bears against the sub-frame and the main frame.
    • 用于印刷机的墨斗具有温度响应元件,用于补偿叶片和墨斗辊之间的间隔的调节,以便即使在极端温度变化下也能保持由叶片供给的墨膜的厚度基本恒定。 墨斗的子框架围绕基本上平行于墨斗辊的轴线的枢转轴线可枢转地安装到印刷机的主框架上,并且枢转角度是温度响应元件的热膨胀的函数 。 在一个优选实施例中,温度响应元件是细长的,容纳在固定到子框架上的导向件中,并且具有抵靠供墨辊的轴承衬套的自由端轴承。 在另一个实施例中,温度响应元件是墨槽的侧壁或平行于墨槽的侧壁的板,并且辊与轴承温度响应元件并且抵靠在墨斗辊的表面上 。 在任一实施例中,温度响应元件由倾斜杆预先施加压力,拉杆使副框架枢转,使得温度响应元件抵靠在副框架和主框架上。
