Abstract: A method for producing halftone dot patterns involves generation of a halftone dot pattern one color channel as a function of the halftone dot pattern generated for another color channel. Placement of dots for one color channel in view of dot placement of one or more other color channels can enhance image quality, promoting improved spacing of dots among the halftone dot patterns generated for the overprinted color channels. Dot placement for a color channel may depend on the number of dots placed for color channels that precede it in the halftoning process. With improved dot spacing in view of inter-channel effects, an inter-channel dot placement method can reduce the incidence of mottle and other image artifacts, improving the visual appearance of the integrated image. A master threshold array may be used to produce halftone dot patterns for all color channels, but applied, in effect, on a shifted basis to promote improved inter-channel dot spacing.

Abstract translation: 产生半色调点图案的方法涉及根据针对另一颜色通道生成的半色调点图案，产生半色调点图形一色通道。 考虑到一个或多个其他颜色通道的点放置，针对一个颜色通道的点的放置可以增强图像质量，促进为叠印的颜色通道生成的半色调点图案之间的点间距改善。 颜色通道的点位置可能取决于在半色调处理中在其之前的颜色通道放置的点数。 鉴于通道间效应的改善，点间距可以减小斑驳和其他图像伪影的发生率，改善整合图像的视觉外观。 可以使用主阈值阵列来产生所有颜色通道的半色调点图案，但实际上以移位方式施加以促进改进的通道间间隔。
