Reproduction of Stained Glass on Transparent Substrate using Wide-Format InkJet printer

摘要

A set of spectral transmittance data for 144 glass tiles (i.e. two test targets of 72 glass tiles each) was analyzed. Chromaticity coordinates and CIELAB values were calculated for each glass tile under two different illumination sources (A and D65). The colour differences (ΔE~*_(ab)) for this pair of illuminants were examined, and the glass tiles with the largest errors were identified and their spectral transmittance curves plotted. A colorimetric reproduction of a stained glass panel was achieved. A digital camera was characterized using two stained glass test targets consisting of 72 glass tiles each. ICC profiles were created for a wide-format industrial inkjet printer for both single-pass and double-pass printing onto a transparent substrate (acetate). Reproductions of the stained glass panel were printed in both single-pass and double-pass modes, and evaluated for both colorimetric accuracy and subjective visual quality.
