The main purpose of this contribution is to report some first preliminary analyses of a new and never investigated decorative technique named Tattoo Wall®, especially the possible changes due to ageing artificially induced by extreme humidity conditions in view of a possible application in crypts, churches or outside wall paintings. This innovative decorating technique involves transferring digital images on wall surfaces through a transfer paper with solvent-based ink and fixative.

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.
