摘要
A set of thin halftone dot patterns 42 used in inkjet printing has a plurality of halftone cells 40 corresponding to respective shade values. Each halftone cell defines a core component of a halftone dot pattern that has been selectively turned " off " with a point 14 at least a predetermined number of points turned "on" to define a halftone dot pattern 46 A plurality of addressable points (12, 14) having at least a predetermined number of " on " points (14) to produce a thin halftone dot pattern (42). Due to the thin halftone dot pattern, the use of a higher addressability in the inkjet printing system results in an undesirable overhead of the printed halftone dot pattern due to the excessive overlap 26 between the printed ink spots 24-A wider range of shading values can be obtained while avoiding ink. The thin halftone dot pattern prevents the occurrence of a top overlap between adjacent ink spots in the core or " inner " component when the halftone dot pattern is printed in an inkjet printing system and maintains the sharpness of the desired halftone cell The entire edge component is maintained as it is. Thin halftone cells can be stored in memory as " glyphs " and recovered by the inkjet printing system to print halftone images with improved quality, a wider range of shade values, and higher addressability .
