which provided adhesion states of pigments on paper fibers. We also visualized a different pigment distribution on paper depending on glue content in pigment mixture. Our results indicated that Raman spectral-imaging would be a promising technique for evaluating a production technologies of ancient ukiyo-e prints that was still unknown at present. 。
Ukiyo-e prints， and printing technologies， such as materials， detailed analysis of color pigments that are one of the most important essential materials used in woodblock prints is required. In this study， is a traditional Japanese art that has been flourished since Edo period. To surmise the production technologies of woodblock prints， Japanese multicolor woodblock prints， carving technologies， we proposed a noninvasive analytical method of color pigments by means of Raman spectral-imaging. Pigment species and its molecular structures were clarified via Raman spectra of pigments. Raman imaging of woodblock prints revealed pigment distribution in plane and cross-section，。
