The elaboration of a graphical design including optically variable features is not straightforward. To facilitate this design conception stage, we have developped a simulation tool which creates an animated sequence of the light effect to be obtained. With this tool, grapical elements can be adapted to obtain the desired effect prior to surface engraving.
The above video compares the design simulation (left) to the actual engraved surface (right, 30mm diam. stainless steel coin).
