local.description.resumoMultispectral Imaging has become an indispensable tool for Cultural Heritage materials and objects analyzing, documenting, and visualizing. This study delves into applying this technique to an 18th-century illuminated manuscript at the Minas Gerais Public Archive, Brazil. Currently undergoing restoration intervention at The Federal University of Minas Gerais, the manuscript exhibits faded writing due to moisture, and the application of multispectral imaging (UV, Visible, and IR) with seven different wavelengths proves highly effective in recovering lost information. The light source was provided from LED and Halogen Lamp, and the result shows a very clear text on the manuscript after the digital processing by ImageJ and PCA. The Minas Gerais Public Archive, established in 1895, plays a vital role in safeguarding the state's documentary and historical heritage. It was the first-time multispectral imaging was applied to cultural objects in Minas Gerais.
