    • The invention relates to a method for illuminating printing plates (5) in which the light from a light source (2) is imaged on a two-dimensional light modulator (4) having a plurality of rows of light-modulated cells (8), and said light is modulated thereby, whereupon the light modulator (4) is imaged on light-sensitive material (5) via an imaging beam path (11), wherein the light-sensitive material (5) is moved relative to the light modulator (4) substantially perpendicularly to the direction of the rows of light-modulated cells (8) at a relative speed and wherein the data pattern to be imaged on the light-sensitive material (5) is displayed beginning in the first row of the light modulator (4) in each row consecutively during a respective exposure time (T, T') and then moved to the subsequent row of the light modulator (4). In order to improve said method, the invention proposes that the image (10) of the data pattern be held substantially stationary relative to the light-sensitive material (5) during the exposure time (T, T').

    • An additional motion is introduced into a scanning operation in addition to the motion inherent in the operation. In a flatbed scanner a linear sensor array is fixedly positioned across the document in an "x" direction and is moved across the document in a perpendicular or "y" direction. In a drum scanner a light beam moves across the document in the "x" direction and the document is moved in the "y" direction. Light reflected from the document is directed to a fixed photoreceptor. With the present invention, the sensor array (14), or the photoreceptor, is moved or vibrated in the "x" direction by a simple piezo electric transducer (15) or by a simple mechanical cam. To eliminate Moire patterns the vibratory movement is a pseudo random series of movements. To introduce a special pattern into the document or to otherwise create special effects, various other types of motion can be used.
    • 除了操作中固有的运动之外,还将另外的运动引入到扫描操作中。 在平板扫描仪中,线性传感器阵列以“x”方向固定地定位在文件上,并且以垂直或“y”方向移动到文档上。 在鼓式扫描仪中,光束以“x”方向跨过文件移动,原稿沿“y”方向移动。 从文件反射的光被导向固定的感光体。 利用本发明,传感器阵列(14)或感光体通过简单的压电换能器(15)或简单的机械凸轮在“x”方向上移动或振动。 为了消除莫尔图案,振动运动是一个伪随机的运动系列。 为了在文档中引入特殊的图案或另外产生特殊效果,可以使用各种其他类型的运动。
