Title: Colorimetric characterization of a desktop drum scanner using a spectral model
Author: Shyu, Ming-Ching James
Abstract: A scanner characterization method based on an analytic spectral model was derived. The method first modeled the spectral formation of each medium using either Beer-Bouguer Law or Kubelka-Munk theory. Scanner digital counts were then empirically related to dye concentrations. From these estimated dye concentrations, either spectral transmittance or spectral reflectance factor could be predicted. These estimated spectral data were used to calculate tristimulus values and then color differences for the target object. A Howtek D4000 desktop drum scanner was colorimetrically characterized accordingly. The average characterization errors were all less than CIELAB color difference of 1.0 for Kodak IT8.7/1, Kodak Q-60C, Fuji IT8.7/1, and Fuji IT8.7/2 targets via this method.
