This award from the Paper Technology Foundation (PTS) certifies that our ink cartridges meet the legal requirements for document authenticity for many applications. Brother ink cartridges are particularly well-suited for printing documents that are intended to be archived for an extended period. When used in conjunction with Brother BP-71 printing paper, which is optimally matched to the composition of the ink contained in the cartridge, we even guarantee lightfastness for up to 100 years. All Brother ink multifunction devices have separate ink cartridges for each color, so only the cartridge that has actually been used needs to be replaced. This way, you help protect the environment and save money. Tested and certified according to RAL-UZ 171, devices using Brother ink cartridges are characterized by their energy-efficient and low-emission operation.
