A method and system for printing a 2D-barcode corresponding to a binary data array and a substrate imprinted with such barcode. The barcode has I first columns of modules and J rows of modules transverse to columns. Each module having a one-to-one correspondence with a bit in a data array and comprising X columns and Y rows of pixels. All pixels are unprinted if said corresponding data bits for a module is not asserted; and otherwise: for pixel columns P(1) through P(X-H) and rows P(1) through P(Y-V), where H is in the range 0 to X-1 and V is in the range 0 to Y-1, all pixels are printed; for first columns P(X-H+1) through P(X) and rows P(1) through P(Y-V),all pixels are printed if a corresponding data bit for an adjacent module in the next module column is asserted; and for columns P(X-H+1) through P(X), rows P(Y-V+1) through P(Y) are not printed if a corresponding data bit for an adjacent or diagonally adjacent module in a next first is not asserted. H and V are not both equal to 0.
