INTRODUCTION
FOCUS brand 60gsm 100% virgin wood pulp carbonless paper sheet
carbonless paper sheet: 70*100, 61*86, 69*89, 65*100
Carbonless paper, also known as NCR paper, Non carbon copy paper, self copy paper, auto copy paper etc, is a kind of paper coated by Microcapsule and/or color Developer. It including CB, CFB & CF.
CB (coated back): The back of the base paper was coated with microcapsule.
CFB (coated front & back): The base paper was coated with color developer on front and microcapsule on back.
CF (coated back): The front of the base paper was coated with color developer on front.
Normally, in a multiple ply NCR documents, the top sheet is CB and bottom sheet is CF, all the other sheets between is CFB.

HOW CARBONLESS PAPER WORKS?
When writing on the top of multiple ply NCR documents, the pressure from the writing instrument causes the microcapsules (on the back of CB & CFB) break, the contains will react with the developer (on the front of CFB & CF) and finally realize auto copy.
