The method for generating a final image for the printing thereof on a lenticular support includes an acquisition of a first file including a plurality of images; an automatic extraction of a determined number of images of the first file as a function of a maximum number of images to extract, the images being ordered according to a first order; a redimensioning of the images as a function of a parameter of density of lenses per unit surface area of a predefined printable support, called the pitch; an interlacing of the extracted images; and a generation of a final image to be printed on a lenticular support.
