Following a discussion of the disadvantages of today's color analysis in an open system architecture, a fundamentally improved reproduction system is proposed. This system includes multispectral sampling and multispectral color information transport via the communication net, using an encoded multispectral format compatible with conventional tristimulus color values. Further answers are given to the problems of the design of a multispectral sampling device. We show that only 14 normal interference filters are sufficient to analyze the spectra precisely enough. A multispectral encoding method produces not only a compatible data format to the conventional tristimulus color values, but is more effective than conventional encoding methods.
