An image applied to the paper that is visible when viewed at an angle. Artificial watermarks are applied after the paper manufacturing process. They can be applied by the paper manufacturer or by the printer. An artificial watermark can be seen from one side only. It is generally applied to the back side but can be applied to the front side also. The watermark is achieved by printing the image in opaque white ink, transparent ink or by using varnish. Also referred to as a simulated watermark.
