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
- 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-

requirements of both the users and the industry for
the different applications. Important advantagesThe International Standard series ISO/IEC 15775
