NO CARBON REQUIRED
If you're of a certain age or older, you might remember that the "cc" on the bottom of a letter meant carbon copy. Although carbon paper is still in use on some forms, it's use has declined since the advent of carbonless paper, and the near obsolescence of typewriters(not quite dead!). Carbon paper is very simple; it's placed, carbonized side down, between two sheets. Putting pressure on the paper with a pen makes the carbon come off onto the second sheet.
Carbonless copy paper also works in a fairly simple way. It consists of sheets of paper that are coated on the bottom and/or the top with micro-encapsulated dye or ink and/or a reactive clay. The back of the first sheet is coated with micro-encapsulated dye. The top of the middle sheet is coated with a clay that quickly reacts with the dye to form a permanent mark. The back of the middle sheet is also coated with the dye. The lowermost sheet is coated on the top surface with the clay with no coating applied to the back side. When the sheets are written on, the pressure from the point of the writing instrument causes the micro-capsules to break and spill their dye. Since the capsules are so small, the print obtained is very accurate.
