Method of digital data recording for obtaining scanned colour partitioning in multicolour printing

专利摘要:
A process of obtaining digital data for color components of a color image includes the steps of quantizing color-processor derived signals to obtain first and second raster signal scans, wherein each of the raster signal scans has a multiplicity of raster spots spaced apart from one another at first and second predetermined distances. The first and second distances of the first raster signal scan correspond substantially to the second and first distances of the second raster signal scan, respectively. Only the raster signal scans corresponding to the color-processor obtained signals in the first and second memory segments, respectively, are stored.
