Abstract

A method for monitoring a process output with a highly abridged spectrophotometer. The method includes securing spectral data for each spectral primary used in a process, measuring spectral data with a highly abridged spectrophotometer for a sample produced by the process, determining an estimated weight for each spectral primary in the sample, and computing spectral data representative of the sample based on the secured spectral data and the determined estimated weight for each spectral primary in the sample.
