Abstract
A printed graphical code has H lines and a W columns i (i=1, . . . W) and a pattern of H×W cells, each at the intersection of a column and a line. Each cell or dot is formed with a drop from a printhead of a continuous inkjet printer and two successive dots of a column are separated by at least one non printed cell. A method for printing each column comprises: retrieving or selecting charges to be applied to each drop for printing the dots of the column from a set of data or database of charges for each of a number of configurations of drops to be printed, the number being equal to or less than 2if H is an even number or equal to or less than 2if H is an odd number; charging the drops for printing according to the retrieved charges; and printing the column.
