Photo engraving formliners turn the façade into a canvas! On a computer, the original photos are converted into a file for the CNC-cutter. Based on the milling file, the positive cast is produced. Depending on the resolution of the motif, the photo engraved formliner creates a fine to rough surface pattern on the façade. That way an impression is created that the image is cut into the concrete. Travelling sunlight creates various effects: perpendicular rays of light make the image disappear. The reliefs cast shadows in lateral rays of light that let the photo clearly appear in the concrete.
