Carbonless form paper is ideal for maintaining a carbon copy of a form, commonly associated with a business transaction. This copy can be provided as a receipt to a customer or for record keeping purposes.
Carbonless forms are often referred to as NCR (No Carbon Required) and are available in 2-part forms, 3-part forms, 4-part forms or 5-part carbonless paper.
Many businesses often use these forms for creating a carbon copy of an invoice, invoice books, receipt book or other business forms.
