Class Information
Number: 358/3.06
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)
Description: Subject matter wherein a discrete gray level of the multi-level image is processed or modulated to generate a halftone which is formed by a pattern of one or more print elements.
