Xerox premium carbonless paper (also known as NCR, no carbon required paper) is perfect to create professional look multi-part forms such as invoices, receipts, delivery notes. Easy to customise with bar codes, sequential numbering or logos - extremely cost-effective. The main benefit of using carbonless paper is that NCR sheets can replicate markings (e.g. a single signature) on multiple copies of a form simultaneously. Being pre-collated, it means that these Xerox carbonless sets have already been put together in the right sequence: a coated back sheet (called CB), containing micro-encapsulated ink at the top, and a chemical clay coated front sheet (CF) at the bottom. When a pressure is applied on the CB sheet, the capsules rupture, and the dye reacts with the clay on the CF below to create a permanent mark: the writing on the first sheet is replicated identical across. Intermediate sheets of carbonless paper with alternated coating ink/clay (called CFB) can also be utilised to extend the original marking on more than two forms. This range of Xerox Premium digital carbonless pre-collated paper, optimised for digital printing, is available in different sets/colours, sizes, thicknesses and collation types (reverse or straight).Xerox premium carbonless paper is available in A4 2, 3 and 4 part collated sets with an array of colour sequences to enhance the look of and the functionality of your multi part forms.
