Class Information
Number: 358/3.16
Name: Facsimile and static presentation processing > Static presentation processing (e.g., processing data for printer, etc.) > Attribute control > Multi-level image reproduction (e.g., gray level reproduction) > Halftoning (e.g., a pattern of print elements used to represent a gray level) > Dithering (e.g., spatial distribution of print elements by threshold matrix) > Ordered dithering (e.g., deterministic or systematic)
Description: Subject matter wherein dithering produces an ordered pattern of print elements forming a halftone pattern, by thresholding a discrete density value (gray level) with a deterministic, usually periodic, array of threshold values.
