The present disclosure concerns a multi-spectral image printing method. The method includes the steps of: - providing a multi-spectral image; - providing a material; - determining changes in a refractive index value of the material permitting to reproduce the multi-spectral image when the material is illuminated; and - generating the changes in refractive index value in the material.
