Hyperspectral imaging as powerful technique for evaluating the stability of Tattoo Wall®
The aim of this work is to present the utilization of hyperspectral imaging to evaluate the stability of Tattoo Wall®, in respect of simulated solar radiation and extreme humidity conditions, for a possible use in the restoration field. Tattoo Wall® is a new and never investigated decorative technique involving transferring digital images on wall surfaces through a transfer paper with solvent-based ink and fixative. This technology shows high stability, but the long-term degradation is not well defined.
