EXCERPT: "This PIMA standard has been developed in order to meet the
industry need for a complete, fully-documented, publicly available
definition of an extended gamut color encoding that is an extension of the
sRGB color encoding. esRGB provides a way to encode output-referred images
that does not limit the color gamut to those colors capable of being
displayed on a CRT display. Some colors in pictorial images printed on
high-quality printers cannot be represented on a CRT display. By using a
standard output-referred extended gamut color encoding, images containing
such colors can be stored and interchanged without limiting or distorting
the colors. The e-sRGB encoding allows these colors to be reproduced
faithfully on the final output medium, within the capabilities of that
medium. Additionally, it is desirable for interoperability reasons to
standardize an extended-gamut color encoding that is an extension of sRGB.
The e-sRGB color encoding specified in this PIMA standard meets these needs.
Currently, an international standard on extended colour encodings for
digital still image storage, manipulation, and interchange is under
development as ISO 22028. Other work is progressing as IEC 61966-2-2. Future
work in this area may progress as part of a new joint working group between
ISO/TC42 and IEC/TC100 that will be set up according to
JTAB Decision 3/2000. After an international standard specifying e-sRGB is
published, it is anticipated that this PIMA standard will be withdrawn."
