ABSTRACT:
A method for increasing the readability of a machine-readable graphical code on a printing surface is provided. The method includes receiving a graphical code image. The graphical code image is an electronic representation of a graphical code. The graphical code image includes a white region and a non-white region adjacent to the white region. The method also includes determining a size increase of the non-white region. The size increase indicates how much the size of the non-white region will increase when the graphical code image is printed on the printing surface. The method also includes creating a size compensated graphical code image by reducing the size of the non-white region by an amount that will substantially compensate for the size increase of the non-white region.
