NCR Paper Manufacturer Reveals: How Does Carbonless Paper Achieve Clear Copying?

Carbonless copy paper is widely used in daily life. Many people wonder why it can duplicate content automatically.
For buyers, printing houses, office supply distributors and clients searching for carbonless paper manufacturers, understanding its working principle helps them pick suitable commercial paper.
This article elaborates on its technical principle, structure and key factors affecting product quality.
First, what is carbonless copy paper?
It is a special paper that realizes multi-copy effect via chemical coating. Unlike traditional carbon paper, it needs no extra carbon sheet. Copies are formed through internal chemical reaction of the paper itself.
It is cleaner, eco-friendly, efficient and easy to store. Widely applied in invoices, logistics waybills, bank documents, medical forms, receipts and commercial contracts.
Why can carbonless paper make automatic copies? The core lies in microcapsule color developing technology. Countless invisible microcapsules are coated on paper surface.
Colorless dye is sealed inside these tiny capsules. When pressure is applied, capsules break open. The released dye reacts with coating on the paper below and forms clear writing and copies.
Now let’s learn its structure. Professional carbonless paper manufacturers mainly produce three basic paper types.
CB paper, also known as top sheet. It has normal front side and microcapsule coating on the back. Used as the first sheet. Capsules on the back break under writing pressure.
CFB paper, the middle sheet. Color developer coated on front side and microcapsules on the back. Placed in the middle position to keep copying downwards. Suitable for 2-part, 3-part, 4-part and 5-part forms.
CF paper, the bottom sheet. Color developer on front side and plain back surface. Serves as the last sheet to finalize color display.

Product quality varies greatly among different manufacturers, mainly due to four reasons.
Different microcapsule quality
High-quality microcapsules feature even particle size, strong compression resistance and long storage life.
Poor-quality capsules lead to faint blurred words and ink leakage.
Different coating technology
Professional manufacturers are equipped with advanced coating production lines.
Superior coating brings even color performance, smooth paper surface, smooth printing and no powder falling off.
Different base paper quality
Fine base paper improves paper toughness, printing effect, storage time and copying sensitivity.
Different color developer
Premium developer owns stable performance, anti-fading property, dark color tone and good resistance to high temperature and humidity. It works perfectly for hot markets such as Middle East and Africa.
Carbonless paper is made into different colors for easy classification. Common colors are white, pink, yellow, blue and green. White is the most common color for the first sheet.
