| description | Copy protections are incorporated into print media by embedding a plurality of latent images formed by different line-screen patterns within a visually integrated setting formed by another different line-screen pattern. The different line-screen patterns of the latent images have line frequencies empirically selected so that upon reproduction at least one of the latent images is rendered more readily discernable to the unaided eye. A masking design formed by another line-screen pattern overlies both the latent images and the visually integrated setting. |
