An ergonomic color image technology produces visually equally spaced 16-step output colors produces for equally spaced 16-step rgb input data on printers and on displays even in the case of different ambient light reflections on the display surface. If the output is equally spaced for example in the CIELAB space then a high visual efficiency is reached. If additionally for printers with CMYN colorants the achromatic colors are only printed by the black colorant N instead by the overprint of three chromatic colorants CMY than additionally a high material efficiency is reached. For an efficient image reproduction it is highly important to produce a relative colorimetric reproduction which is linearly spaced as function of relative CIELAB data. Therefore the definition of meaningful relative CIELAB coordinates is necessary. For this any device is described by six chromatic colors OLV and CMY. The six device colors OYLCMV form a chroma hexagon in the (a*, b*) CIELAB diagram. In the third dimension the achromatic color Black N is located at the top and White W is at the bottom.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
