Figure Lengend Snippet: a Schematic diagram of three-dimensional encoding using green, yellow, and red. b Photographs of three-dimensional colorimetric encoding results with varying concentrations of green, yellow, and red solutions (left), and displaying the RGB values of the encoding results (right). The images on the right have been processed using pseudo-color. c Spectral characteristics of the three original solutions: green, yellow, and red solutions. d Graph showing the RGB value relationship between a mixed solution and single-color references. e Graph showing the absorption spectral relationship between a mixed solution and single-color references. f Decoding results of three-dimensional colorimetric encoding system through spectral and visual analysis. The coordinates represent the relative concentration of the original solutions. g Schematic diagram of the hyperspectral imaging for reflectance spectral capture and image analysis. h Hyperspectral reflectance spectra of three original single-color solutions. i Trend chart of the reflectance spectral changes with altered single-color concentration in the coding mixture. Y yellow, G green, R red. Source data are provided as a Source Data file.

Article Snippet: Additionally, the three-dimensional Colorimetric coding results were photographed using a hyperspectral camera (Specim IQ, Finland), and the reflectance spectra were analyzed using ENVI software (v 5.6).

Figure Lengend Snippet: Examples of samples from different subsets: ( a ) mock-ups of historical inks on cotton paper, ( b ) pencil mock-ups, ( c ) mock-ups of artificially aged metallo-gallate inks, ( d ) manuscript of the Provincial Historical Archive of Granada, ( e ) illuminated manuscript from the Archive of the Royal Chancellery of Granada, ( f ) family tree from the Archive of the Royal Chancellery of Granada; and ( g ) hyperspectral capture using the Pika IR+ camera.

Article Snippet: Two line-scan hyperspectral cameras from Resonon Ltd. (Bozeman, Montana, USA) were used, together with the associated software Spectronon Pro 3.5.5: the Pika L and the Pika IR+.
