An ICC profile defines the bidirectional conversion between a neutral "profile connection" color space (CIE XYZ or Lab) and a selected colorspace, in this case both RGB and CMYK. The precision of the conversion depends on the profile itself, the exact methodology, and because the gamuts do not generally match, the rendering intent and ...
Color space conversion is the translation of the representation of a color from one basis to another. This typically occurs in the context of converting an image that is represented in one color space to another color space, the goal being to make the translated image look as similar as possible to the original.
One starts with a white substrate (canvas, page, etc.), and uses ink to subtract color from white to create an image. CMYK stores ink values for cyan, magenta, yellow and black. There are many CMYK colorspaces for different sets of inks, substrates, and press characteristics (which change the dot gain or transfer function for each ink and thus ...
If you wish to obtain CMYK values for these colors, you will get appropriate conversion values from your graphics application when you define the type of ink and paper you will be printing on. A CMYK value is meaningful only if you can specify what ink–paper–process standard it is supposed to be used with.

The most noticeable result of using light cyan and light magenta inks is the removal of a distinct and harsh dither dot appearance in prints that use light shades of cyan or magenta produced with only the CMYK inks. Usually when printing a dark color the printer will saturate an area with colored ink dots, and conversely, for a light color it ...

Hexachrome was discontinued by Pantone in 2008 when Adobe Systems stopped supporting the HexWare plugin software. While the details of Hexachrome were not secret, its use was limited by trademark and patent to those obtaining a license from Pantone. The inventor of Hexachrome is Richard Herbert, who is also the president of Pantone Inc. [1]
