Abstract: A continuous-tone image, which can be in full color, is scanned to produce color-separation images in halftone dots. Edges of features in the scanned image are sensed, and the positions and shapes of the halftone dots that define corresponding edges in the halftone reproductions are adjusted so that they conform better to the feature edges. This reduces or eliminates the apparent serrations or roughness of feature edges in the halftone reproductions otherwise caused by misalignment of the halftone dots with the feature edges and improves image definition.
Abstract translation: 可以全色的连续色调图像被扫描以产生半色调点的色彩分离图像。 感测扫描图像中的特征的边缘，并且调节限定半色调复制品中相应边缘的半色调点的位置和形状，使得它们更好地符合特征边缘。 这减少或消除了半色调复制品中的特征边缘的表面锯齿或粗糙度，否则由于具有特征边缘的半色调点的不对准而引起的，并且改善了图像定义。
