: Modern researchers use Non-Invasive Analysis like X-ray fluorescence (XRF) and infrared spectroscopy to identify the pigments and tools used in these intricate patterns.

Developed to solve technical issues in early cinema, Sonochrome film was engineered to allow sound-on-film recording without the tinting interfering with the photoelectric cells. Sonochrome - Medieval Puntz

: Film historians use spectral analysis to digitize Sonochrome prints accurately.

In medieval artistry, "puntz" or punchwork refers to the technique of creating texture and light-reflecting patterns on surfaces like gold leaf or metal.

: Art historians use similar light-based technology to uncover "palimpsests"—hidden text or drawings beneath the surface of medieval works.
