摘要

"SEMI-TOM STANDARD, DESEMI-TOM STANDARD SET, METHOD TO CREATE A DESEMI-TONE MASK, SEMI-TOM MASK, AND DESEMI-TOM THRESHOLDER MATRIX" A stochastic halftone pattern was invented which has a narrow range power spectrum due to the incorporation of a dot growth process. The narrow range power spectrum can be matched to the resolution characteristics of specific printers, resulting in smoother printed halftone textures. The spectrum of a halftone pattern can be made anisotropic (angularly dependent),helping to decouple sets of boxes for colored printing with noise or corrugated tint.
