Carbonless(NCR) paper
Carbonless copy paper (CCP), also called non-carbon copy paper or NCR paper (which stands for ""no carbon required"", a backronym derived from its creator National Cash Register), is a type of coated paper designed to transfer information written on the top sheet to the sheets beneath. It was developed by chemists Lowell Schleicher and Barry Green, as an alternative to carbon paper and is sometimes misidentified as such.
Carbonless copying provides an alternative to the use of carbon copying. Carbonless copy 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 writing or impact printing), the dye capsules rupture and react with the clay to duplicate 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 multipart stationery.

How Does Carbonless Copy Paper Work?


As we noted, NCR paper is typically a pair of papers that contain different materials from each other. Highly sensitive microcapsules of chemicals that produce color are embedded on the bottom side of the top sheet of paper. The microcapsules release their contents 

upon the application of force onto the areas containing them. This alone is not enough to produce an additional copy — you cannot 

reproduce writing if you use just any piece of paper under this sheet. The chemical within the CB can produce color, but it cannot 

release it without the help of another substance. That is where the bottom sheet of carbonless copy paper comes in. Its top side 

has a layer — called the CF, which naturally stands for ""coated front"" — containing a reactive sort of clay. When the chemical 

from the CB is released onto the clay, the latter releases a substance of its own that can bring out the color in the former. 

The result of the ensuing chemical reaction is the perfect reproduction of writing from the top sheet to the bottom one. 

All of this happens without the use of carbon black, or any carbon — hence the name.

Thermal Paper FAQ- Everything You Need To Know

Find clear answers to the questions about thermal paper rolls, printing, and applications. From lifespan to printer compatibility, we help you understand ost Common every detail of the thermal paper industry.

A：

It relies on a "microcapsule chemical reaction" — the back has microcapsules with colorless dyes (color-forming layer), and the front has acidic color developers (color-receiving layer). Pressure breaks microcapsules, and dyes react with developers to show visible colors, no extra carbon paper needed.​

A：

No, just use by purpose:​
Rolls/sheets: Stack "color-forming layer paper" and "color-receiving layer paper" for printer pressure-triggered copying.​
NCR pads/forms: Pre-stacked at factory (e.g., 2-ply: color-forming top, color-receiving bottom); write or use dot-matrix printers directly.​

A：

3 main reasons:​
① Insufficient pressure (light writing/printer pressure → incomplete microcapsule rupture).​
② Uneven coating (poor-quality paper → uneven dye/developer distribution).​
③ Improper storage (high temp >35℃/humidity >80% → deactivated microcapsules/developers).​

A：

Under normal conditions (15-30℃, 40%-60% humidity), text stays stable for 3-5 years. High temp/humidity/strong light may cause fading; store important docs in sealed cabinets.

A：

No, match printer type:​
① Compatible with dot-matrix (sufficient pressure for NCR pads/sheets) and roll printers (for carbonless rolls).​
② Inkjet/laser printers only print single sheets, no copying (insufficient pressure).​

A：

Mainly for distinguishing ply purposes (e.g., white for customers, pink for retention). Same coating formula for all colors (no effect on copying); custom colors (e.g., light green for medical use) available.​

A：

Ordinary BPA-free carbonless paper is "recyclable waste". Medical-scene waste (with medical contamination) follows medical waste rules. Prioritize paper meeting EU REACH/US FDA standards for better
