What ISO 12639 (TIFF/IT) requires
Compliance with ISO 12639, governing the Tag Image File Format for Image Technology (TIFF/IT), mandates strict adherence to a specific set of structural and content-based rules for digital graphic arts data exchange. A file must present a valid profile declaration, which is restricted to Line Work (LW), High-resolution Continuous-tone (HC), or Binary Picture (BP) profiles. Each profile carries distinct technical prerequisites. For instance, LW files necessitate monochrome photometric interpretation and CCITT Group 4 compression. HC files, conversely, demand either CMYK or RGB colorspace and must use uncompressed or LZW compression schemes. BP profile validation hinges upon the presence of an Image File Directory pointer and valid linked image data. Universally, all conforming files must contain mandatory geometry tags, possess defined colorimetric data, and exhibit a compliant Image File Directory (IFD) structure. Furthermore, the standard imposes a hard ceiling on image fidelity, stipulating that resolution cannot exceed a maximum of 9600 DPI. These constraints ensure consistent and predictable file interchange within professional prepress workflows, and BIDDA's validation logic rigorously enforces every one of these requirements.
