TY - RPRT A1 - Richter, Klaus T1 - Definition of extended print colour space cmyolvnw* according to ISO/IEC 15775 or DIS ISO/IEC 19839-1 to 4 and comparison with sRGB and scRGB colour spaces according to IEC 61966-X N2 - The International Standard series ISO/IEC 15775 and DIS ISO/IEC 19839-1 to 4 for specifying image reproduction properties of colour reproduction processes analog-analog (copiers), analog-digital (scanners) and digital-analog (printers, monitors) seem to overlap with the International Standard series IEC 61966-X for scanners, printers and displays. But there are fundamental differences. In the ISO/IEC standards the coding of colours is based on reflective colours (defined for standard offset printing) and in the IEC series on luminous colours (defined for television). Members of the standard groups ISO/IEC JTC1/ SC28 and IEC TC100 TA2 which developed the above standards try at the moment to define extended colour spaces (wide gamut colour spaces) compatible with the present spaces of the standards ISO/IEC 15775:1999-12 and IEC 61966-2-1:1999- 10.The extended spaces should match the requirements of both the users and the industry for the different applications. Important advantages and disadvantages of both solutions based on coding of reflective and luminous colours are presented.
