Abstract: Techniques are described herein that mitigate warpage during laser marking on a plastic security document. A method of laser marking a feature onto a plastic card includes electronically dividing an image of the feature into a plurality of sections. The method includes laser marking a first one of the sections on the document and laser marking a second one of the sections on the document. The first section is not contiguous with the second section.
