Abstract: The present disclosure relates to a system for verifying homogeneity in clusters and comprises a processor and a non-transitory computer readable memory storing instructions that are executable by the processor. The system creates at least one adjacency matrix representing a relationship between rows and columns of a table. The system applies an algorithm to the table to identify a first set of clusters. For each identified cluster, the system compares a computed dispersion value to a predetermined threshold. The cluster is associated as being homogeneous if the threshold is not met and not homogeneous if the threshold is met. The system reapplies the algorithm to the set of non-homogenous clusters within the data set and repeats the thresholding processes until each cluster resulting from the data set is homogeneous. Upon reaching the desired homogeneity for each cluster, the system recombines the clusters sequentially while keeping the each identified cluster together.

Abstract: A method is provided for rendering a color image with a plurality of separations with a multi-level successive-filling halftoning process using a single screen for a plurality of separations. For a separation to be processed, first, from the possible multiple levels for the separation, the set of levels that would be used and the number of dots corresponding to the different levels are decided. These decisions are based on the input level for the separation and input levels for the prior process separations. The location of the dots to be printed for the different levels for the separation is then decided by using the halftone screen, while simultaneously taking into account the placement of printed dots for the prior separations. The selection is done so as to best disperse dots and minimize overlap.
