How many types of carbon paper are there?

Carbonless papers consist of four distinct types of paper, Coated Back or CB , Coated Front and Back or CFB, Coated Front or CF, and self-contained paper or SC .

What is carbon paper made of?

Carbon paper consisted of a sheet of paper that was coated on one side with a layer of carbon black (soot) bound with wax. When placed between an original and a second piece of paper to be copied onto, carbon paper would transfer marks made by the pressure applied by a typewriter or pen.

The microcapsules burst under the pressure of writing so that they release the reaction fluid onto the next sheet.

How is carbon paper made in the US?
