In the old days before NCR printing was even envisioned, scribes were hired to duplicate important documents. If anyone wanted a copy of a document it would take months to get the work done. The human nature is never too patient to keep waiting for months and years so they started to research on some easy way and thus the carbon paper was invented. This magical paper was inserted between two pages and the page below the carbon paper would become the exact copy of the original paper. The carbon paper solved many problems but still it was a lot of hard work and messy. The carbon paper would leave its mark on anything that came in contact with its carbonized surface so there were chances of smudging the copy while also smudging the hands.
The corporate sector was not satisfied with the carbon paper and they demanded a cleaner and a better way to duplicate their papers. Something was needed with which could serve the same purpose, but eliminate the hassles and the mess. The great moment came in the 1950’s when scientists made a breakthrough and emerged with a new product called the http://www.printcosmo.com/Monthly-Promotions/2-Part-Carbonless-Forms.html . These papers acted the same as when a carbon paper was kept between two pages. The upper page would leave its marks on the lower page but without any carbon paper in between and without any mess or smudges.
These papers became a great success instantly and it was called the NCR paper using the acronym No Carbon Required for marketing purposes. NCR was easy to remember and it also defined its use without any problems. As these papers became available in prints too the process was fairly named http://www.printcosmo.com/Carbonless-Forms/NCR-Printing.html . The NCR paper can have any number of sheets underneath to get the copy on. Usually companies opt for two pages while some large companies even go to the extent of three pages for the set. A normal 3 pages NCR paper is made up of the following papers.
- The top sheet which is known as the CB. It is coated backwards with ink.
- Middle sheet which is known as CBF. It is coated back and front so it receives the impressions on its face and also transfers it to the sheet below it.
- The last sheet which is known as CF. It is simply coated on the front while the back is plain paper. It does not transmit the impressions on the paper below.
When we take the 2 part carbonless forms simply remove the middle sheet or the CBF sheet. It just consists of the CB and the CF pages. The top sheet contains the pressure sensitive coating on the backside so that it starts to create an impression on the sheet below. The second sheet in the 2 part form is the CF sheet which is coated on the face so that it easily receives the writing which comes from the pressure of the sheet above it. This simple yet useful invention has now made it very easy to duplicate pages without wasting any time or create a mess.
