- At least two primary images are obtained, for example extracted from a .mpo file, a composite image, or generated by a 3D modeling software or by an editing software. images.
- a printing software is pointed to a memory zone of the programmable machine comprising the .mpo file or the data corresponding to the two primary images.
- a second step comprises the identification of a support 100 ( Figure 16) for printing at least two primary images to produce a composite image.
- a user manually chooses from a list of print media comprising several entries the entry corresponding to the medium for printing at least two primary images to produce a composite image in the desired final format and with the desired quality (the other print media in the list include for example 'standard paper', 'photo paper', etc.)
