Ncr Paper

NCR paper or No Carbon Required paper is an effective yet simple method of replicating instantly on what to write. It is commonly used for any kind of multi part form such as bill of ladings, work orders, invoices, inventory sheets, order forms and any other document where more than one copy is required. There is an array of colors available for the copy sheet, such as white, Canary, Gold, pink, green and blue. In most instances white is the top copy and subsequent colors are beneath dependent on the number of duplicated pages required. For example, two copies of document being made, the papers would have a white top sheet and one colored second sheet below, which would be called two-part or duplicate. For three copies, there would be a white top part and two colored parts below, called three-part or triplicate. Four copies would be called four-part or quadruplicate. The back of the first sheet is coated with micro-encapsulated dye (referred to as a Coated Back or CB sheet). The lowermost sheet is coated on the top surface with clay that quickly reacts with the dye to form a permanent mark (Coated Front, CF sheet). Any intermediate sheets are coated with clay on top and dye on the bottom (Coated Front and Back, CFB sheet).

This type of paper is made using new technologies and processes in order to make it have the features that allow it to perform the task of duplicating documents with ease. On the surface above of the one with the reactive clay is applied by pressure it transfers the same information on the surface below it. Because of that principle, it is possible to make a certain number of copies with the same information if you properly stack multiple sheets of NCR paper on top of each other and then writing on the top most sheet of the stack. 
Instead of inserting a special sheet of carbon paper in between the original and the intended copy, NCR Paper has micro-encapsulated dye or ink on the back side of the top sheet, and a clay coating on the front side of the bottom sheet. When pressure is applied (from handwriting or impact printing), the dye capsules burst and react with the clay to form a permanent blot duplicating the markings made to the top sheet. Intermediary sheets, with clay on the front and dye capsules on the back, can be used to create multiple copies; this may be referred to as multi-part stationery.
