NCR BOOK (No Carbon Books)
What is an NCR book? NCR (no carbon required) or carbon less books have eliminated the need for carbon paper between sheets to create multiple copies of the same page. The back of the top sheet of paper is chemically treated to transfer the pen pressure from the first page to the subsequent pages. The bottom side of carbon less NCR paper is coated with micro-encapsulated dye that breaks when pressed. The top of the second sheet is coated with clay that reacts with the dye to form a permanent mark. When the top sheet is written on, the pressure causes the micro-capsules to break and release the dye.
We also offer the above in pad form. The difference between books and pads are that in the case of pads, instead of having them stapled and then bound with spine tape and perforated, they are just glued into sets at the top and then glued into pads of 50 or 100, with a board backing and a chip board writing shield.
