Why CT Works for Autographs
Autographed items can hide forged signatures, added materials, or concealed damage. CT imaging reveals ink penetration depth, substrate density, and internal repairs. It can detect overwritten signatures, added patches, or replaced surfaces.
Detecting Tampering
CT exposes density changes caused by adhesive patches, tape, or altered layers.
Preserving Collectible Value
Collectors can authenticate items without removing frames or protective cases.
