The invention concerns a method for producing a particular photoluminescent polychromatic printed image which consists in: producing at least one set of at least three filtered monochromatic images (6a, 6b, 6c) from a particular original polychromatic image visible in the visible light filtered with a spectral bandwidth not greater than 15 nm, along at least three wavelengths of fundamental colours equal to the wavelengths of luminescent pigments which are used, with the corresponding filtered monochromatic images (6a, 6b, 6c) for printing separately, above one another, three printed monochromatic pictures (8a, 8b, 8c). The invention also concerns the resulting picture, a protective device and a document bearing such a picture.
