Fig. 6From: Creation and reference characterization of Edo period Japanese woodblock printing ink colorant samples using multimodal imaging and reflectance spectroscopyOffset FORS comparison of laked and dye extracts printed on sized and unsized paper. For each figure, spectra are organized as A laked pigment on sized paper, B laked pigment on unsized paper, C dye extract on sized paper, and D dye extract on unsized paper. In both cochineal (top) and madder (bottom) the dye extract on sized paper behaves similarly to the alum-laked pigment. The alum-laked pigment is not effected by the sizing or lack of sizing on the paperBack to article page
