    • Apparatus and method for creating quality pictorial color images include a charging device for uniformly charging a photoconductive member of a first tri-level xerographic module to a predetermined voltage level; using a controller and a ROS device for creating tri-level latent electrostatic images including CAD image areas and DAD image areas having different voltage levels respectively; developing the CAD image areas and the DAD image areas with yellow (Y) and a first black (K1) marking materials respectively to form a first composite color separation image of a desired final pictorial image; transferring the first composite color separation image onto an intermediate transfer member; similarly forming and developing a second composite color separation image on a second tri-level xerographic module using Magenta (M) and a second black (K2) marking material; transferring the second composite color separation image, in registration with the first composite color separation image, onto the intermediate transfer member such that yellow Y and the second black K2 are superimposable; similarly forming and developing a third composite color separation image on a third tri-level xerographic module using Cyan (C) and an optional color (X1); transferring the third composite color separation image in registration with the first and the second composite color separation images, onto the intermediate transfer member to form a desired final pictorial image including desired color superimpositions; and transferring the desired final pictorial image at a substrate transfer station onto a substrate for fusing.
    • 用于产生质量图形彩色图像的装置和方法包括用于将第一三级静电复印模块的感光体均匀地充电至预定电压电平的充电装置; 使用控制器和ROS装置来分别创建包括具有不同电压电平的CAD图像区域和DAD图像区域的三层静电图像; 分别用黄色(Y)和第一黑色(K1)标记材料显影CAD图像区域和DAD图像区域,以形成期望的最终图形图像的第一复合颜色分离图像; 将所述第一复合色分离图像转印到中间转印部件上; 类似地使用品红(M)和第二黑(K2)标记材料在第二三层静电复印模块上形成和显影第二复合颜色分离图像; 将与第一复合色分离图像对准的第二复合色分离图像转印到中间转印部件上,使得黄色Y和第二黑色K2重叠; 类似地使用青色(C)和可选颜色(X1)在第三三层静电复印模块上形成和显影第三复合色分离图像; 将与第一和第二复合颜色分离图像对准的第三复合颜色分离图像转印到中间转印部件上以形成包括期望的颜色叠加的期望的最终图形图像; 并将所需的最终图形图像在衬底转移站处转移到用于熔化的衬底上。
