Better parameters for your Photoshop 5.02 +, CSx

The RGB workspace profiles such as "Adobe RGB 98" proposed by Photoshop, Illustrator etc. have a D65 white point, increasing risks of error depending on the rendering intent you use in your I.C.C. production workflow, taking into account the recommendations of ANSI and ISO are for D50 lighting throughout the graphic chain.

The Adobe Wide Gamut profile has a D50 white point but if it is adapted to photographic applications, it has an unnecessarily broad chromatic gamut for Graphic arts for traditional CMYK printed work.

The European Colour Initiative committee (ECI) thus recommends a workspace better adapted to the requirements and output norms, and publishes a free RGB profile workspace named ECI RGB.

Below the 2D comparison of ECI RGB and cromalin Eurosprint color gamut, in the C.I.E. xyY absolute space of colors, and in C.I.E. Lab space:
