Abstract: According to this method, a mathematical surface ( P ref BF ) is determined (104), a printing head is brought into a first position and then into a second position, where a first impact and a second impact are printed (106, 110), then the coordinates of a characteristic point ( P 1 , 4 BF , P 2 , 4 BF ) of the first or second impact (108, 112) are measured. We express (114) the coordinates of a first intersection point ( I 1 , 4 BF ) and those of a second intersection point ( I 2 , 4 BF ) . We express (120) a deviation ({right arrow over (?k)}) based on the coordinates of the characteristic points ( P k , j BF ) and intersection point ( I k , j BF ) . We construct (122) an objective function (F) whose variables are the deviations ({right arrow over (?k)}). We determine (124) values for six parameters (X1-X6) of a passage matrix (TTCP?PG) which minimise the objective function (F).
