The Impact of Spectrally-Stable Ink Variability on Spectral Color Management

چکیده
Typical color image processing techniques use profiles consisting of sparse multi-dimensional lookup tables that interpolate between adjacent nodes to prepare an image for rendering. It has been suggested that spectral image processing could make analogous use of these techniques. A lookup table for spectral matching will relate spectral correlates to values related to printer digital counts. Previous research has shown that within a multi-colorant printer’s digital gamut there is often a large amount of spectral redundancy. Thus, without special consideration, it could be possible for adjacent nodes in a lookup table to have spectral consistency but digital count inconsistency. The colorimetric impact of lookup table interpolation within such situations was investigated.

Two criteria for selecting ink sets for six-color lithographic printing are discussed. The first is the volume, in CIELAB space, of an approximation of the gamut. The second is the number of pixels within a digital image (or images) whose colors are contained within the approximate gamut. In order to obtain a balance between accuracy and efficiency, the different steps in the process are priori...
