Device dependent color signals to/from a system should be converted into a standard color signal, such as CIELAB, for media independent color reproduction. In case of applying CIELAB to the standard color signals, the relationship between CMYK and L*a*b* is complicated in contrast to NTSC RGB and YIQ or others. This paper presents a transformation from L*a*b* to printer density by the Prism Interpolation) and Slant Prism Interpolation) have been developed to realize a flexible and high-speed color conversion.

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.
