    • A method is disclosed for accurate reproduction of high-quality halftone images comprising microdots by means of lithographic plate materials which comprise a heat-sensitive positive-working coating that requires wet processing. Such microdots have a dot size ≦25 μm and may be obtained by stochastic screening or by amplitude-modulated screening at a ruling of not less than 150 lpi. It has been established that the “physical right exposure energy density” (physical REED) lies in the range from CP to 1.5*CP, wherein the physical REED is defined as the energy density at which the physical area on the plate, occupied by a microdot corresponding to a 50% halftone in the image data, coincides with the 50% target value; and wherein CP is the clearing point of the plate which is defined as the minimum energy density that is required to obtain, after processing, a dissolution of 95% of the coating. An accurate reproduction of microdots can therefore be achieved by exposing the material with light having an energy density in the range from CP to 1.5*CP. Loss of microdots by overexposure is thereby avoided.
    • 公开了一种用于通过平版印刷材料精确再现包含微点的高质量半色调图像的方法,该平版印刷材料包括需要湿法处理的热敏正性涂层。 这样的微点具有<25μm的点大小,并且可以通过随机筛选或通过幅度调制筛选获得,尺寸不小于150lpi。 已经确定的是,“身体右曝光能量密度”(物理REED)在CP到1.5 * CP的范围内,其中物理REED被定义为板上的物理区域的能量密度,由 在图像数据中对应于50%半色调的微点符合50%的目标值; 并且其中CP是板的清除点,其被定义为在加工后95%的涂层的溶解所需的最小能量密度。 因此,通过用能量密度在CP至1.5×CP范围内的光使材料曝光,可以实现微点的精确再现。 从而避免由于过度曝光导致的微点损失。
