Abstract: The invention concerns an assembly for printing on a substrate having a camera for recording a reference pattern; a computer connected to the camera to store and modify, if required, data (N) concerning the reference pattern; and a printer whereof at least the print head is controlled by a printer file (FI) generated by the computer. The invention is characterised in that it includes a system for supporting and moving the substrate; for analysing and comparing a pre-recorded pattern with a pattern located on the substrate, and for adapting or not the data (N) concerning the reference pattern as a result of the comparison; and for generating a printer file (FI) based on the data whether or not modified.
