Creating a form or document where you need the user to make a duplicate transfer of information onto an underlying second sheet? Carbonless or NCR (No Carbon Required) paper is used for forms or documents where you want to create a copy or imprint of the top sheet information onto one or more secondary sheets - in the same manner as old fashioned carbon paper. The key difference with carbonless paper is that it uses a technology that allows this process to happen without the need for unsightly carbon paper. The Carbonless range has options for various thicknesses.
