A method of personalizing a security document includes a formation of a personalized output image (5) by printing a two-dimensional pattern (6) consisting of a single continuous line (8). In this printing, at least one line parameter of each line unit (10) of the single continuous line (8) is varied in accordance with color values of the image units (9) in the personalized input image (4) to create a personalized output image having a unique appearance. If the printed personalized output image (5), in particular, the single continuous line (8) has an electrical conductivity above a given threshold value, the personalized output image (5) may form part of an RFID antenna (18) of the security document (10).

Method for generating a control file for a digital printer, wherein the control file is provided for printing a decorative pattern on a sheet. The decorative pattern is modified such that it comprises a concealed code. The method comprises the steps of - printing a first master decor showing the decorative pattern on a first sample of the sheet, thereby obtaining a first sample sheet comprising the first master decor; - performing a process on the first sample sheet comprising the first master decor, wherein the process causes a deformation of the printed first master decor on this first sample sheet; - measuring this deformation on the first sample sheet; - modifying the first master decor thereby obtaining a second master decor, wherein the second master decor is modified compared to the first master decor such that it compensates for the deformation occurring in said process; - generating a control file for a digital printer for printing the second master decor on a sheet having the same characteristics as the first sample sheet; characterized in that the printed second master decor comprises the concealed code invisible to the human eye but machine readable.
