Carbonless Paper: Working Principle and Applications
Working Principle:
Carbonless paper (also called NCR paper, from No Carbon Required)
enables duplicate writing or printing without using traditional
carbon sheets. It relies on chemically coated layers that react
under pressure to produce copies.
Multi-part Structure: Typically consists of two or more sheets:
CB (Coated Back) Sheet: The top sheet, coated with
micro-encapsulated dye on the back.
CF (Coated Front) Sheet: The bottom sheet, coated with a reactive
clay or polymer that develops color when exposed to the dye.
CFB (Coated Front & Back) Sheet: Middle sheets (if used) have both
coatings to transfer impressions to subsequent layers.
How It Works: When pressure is applied (e.g., writing or printing),
the microcapsules on the CB sheet rupture, releasing dye that
reacts with the CF sheet’s coating, creating a visible mark.
Applications:
Carbonless paper is widely used in scenarios requiring quick, clean
duplication:
Business Forms: Invoices, receipts, purchase orders, and delivery
notes.
Legal & Administrative Documents: Contracts, work orders, and
triplicate forms.
Medical & Laboratory Use: Prescription pads, lab test records.
Retail & Logistics: Shipping manifests, packing slips.
General Office Use: Notepads, memos, and duplicate checks.
Its advantages include no smudging, no need for carbon sheets, and
efficient multi-copy record-keeping. However, digital alternatives
(like electronic forms) have reduced its usage in some sectors.
