The KH COPY paper allows you to create several copies in one go. It can be used wherever there is a need to fill in forms in a quick and conclusive manner, even in the absence of common office equipment. Common applications include government institutions, insurance companies, banks, postal and delivery services, freight forwarders, carriers, etc.
The carbonless copy effect is based on a combination of a microencapsulated colorless dye (color former) applied to the back side of the top sheet (called Coated Back or CB) with a color-developing coating on the front side of the bottom sheet (Coated Front or CF). Under pressure imposed by handwriting, typing or impact printing, the microcapsules rupture and the dye reacts with the color developer, resulting in the image formation on the bottom sheet. Intermediate sheets have to be coated on both sides – with a CF layer on the front and a CB layer on the back (Coated Front and Back, CFB).
SC (Self Contained) paper is coated on the front side with a suspension containing both the dye capsules and the color developer. It can be used as a bottom sheet in combination with standard (non-NCR) paper as the top sheet, as well as for ribbonless impact printing. If more copies are required, the paper can be coated with an SC layer on the front and a CB layer on the back (Self Contained/Coated Back, SC/CB).
NCR coating can be applied to a variety of base papers as required, including, above all, security papers - see Carbonless Security Papers
