perf-embossing - Embossing by a method that creates very small and discrete ruptures at precisely controlled locations within the material. This process was invented at Scott Paper Company decades ago and was originally used for ScotTowels(R) (trademark now owned by Kimberly Clark). Both embossing rollers in perf-embossing are usually engraved with the same pattern of discrete, raised, male elements, and the pattern is designed so that these elements pass between each other when the rollers are engaged in a nip. This is also known as interdigitating embossing.
