Standard and Wide Gamut colour code (SGcode and WGcode) compatible with CIELAB, ISO/IEC 15775 and DIS ISO/IEC 19839-1 to 4 for colorimetric colour management and communication

  • For colorimetric colour management and communication 8bit colour codes in perceptive space (*colour space) are described. Two Standard Gamut Colour codes for Printing (PR) and Television (TV) and one universal Wide Gamut Colour code (WGcode) which includes all real colours of both PR and TV. There are reverse transformations between the two different SGcodes of PR and TV, the universal WGcode and the CIELAB colour coordinates. The SGcodes and the WGcode are compatible with CIELAB, ISO/IEC 15775 and DIS ISO/IEC 19839-1 to 4 which specify image reproduction properties of colour copiers, printers, scanners and monitors. These standards correspond to DIN 33866-1 to 5. The SGcodes and the WGcode can be calculated for all colours of the four ISO/IEC-test charts which are all defined in CIELAB coordinates. Main colour series are equally spaced in CIELAB colour space both in lightness L* and chroma C*. Up to now there are productions of DIN (German Standard Institute) and JBMA (Japan BusinessFor colorimetric colour management and communication 8bit colour codes in perceptive space (*colour space) are described.

Up to now there are productions of DIN (German Standard Institute) and JBMA (Japan Business Machine Makers Association) according to ISO/IEC 15775 which can be used for all applications. The 8bit SGcode of television is similar compared to the nonlinear 8bit code of the sRGB colour space defined in IEC 61966-2-1:1999-10 which is incompatible to CIELAB and ISO/IEC 15775.zeige mehrzeige weniger
