Abstract
Overview
ISO 12639:2004/Amd 1:2007 is an amendment to the TIFF/IT prepress exchange standard that defines how JBIG2-Amd2 compressed codestreams are incorporated into TIFF/IT image files. The amendment enables the use of JBIG2-Amd2 for TIFF/IT-BP (binary picture) and TIFF/IT-SD (screened data), delivering efficient, lossless bi-level compression suited to halftone and binary printing data.
