A computer implemented method for proofing a selected part of a graphical data input file for output to an output device by automatically adjusting at least one graphics feature in the input file to compensate for a predetermined resolution limit. The method includes identifying one or more portions in the selected part of the input file having an initial thickness less than the resolution limit, determining a set of optimal anisotropic offset parameters that will bring the one or more portions above the predetermined resolution limit with a minimal total offset value, applying an offset using the anisotropic offset parameters to modify the selected part of the input file to give the one or more portions an adjusted thickness greater than the initial thickness, and creating an output file comprising the at least one graphics feature having the adjusted thickness.
