The blue-grey thermal paper Blue4est from Koehler completely does without with the use of chemical developers. Instead, a purely physical reaction is used. During printing, the functional layer becomes transparent under the influence of heat and the underlying black layer becomes visible. As a result, the receipts are environmentally friendly and approved for direct contact with food - ideal for retail and hospitality. They are also durable up to 35 years and may be easily disposed of in waste paper.
