Abstract

We developed a multi-spectral scanner by using LEDs array with different spectral radiant distribution to measure high accuracy spectral characteristics of printing proof. Five kinds of LEDs were selected from the combination of 40 LEDs on the market to minimize the color difference ΔE*94 between measured and estimated reflectance spectra of 81 kinds of color charts by using polynomial regression and clustering methods. Reflectance spectra of 928 color charts were measured and estimated by using the scanner and the Wiener estimation method. As a result, average color difference ΔE*₉₄ was 1.23 when 81 color data were used to calculate the Wiener estimation matrix.
