This selection of creative premium papers certified HP Indigo have been specially optimised for printing on liquid toner digital presses. HP Indigo digital presses use liquid electrophotography based on ElectroInk® in combination with a hot blanket. The ElectroInk® is heated and blended into a smooth film - this produces an image that is completely definite: after the ink is transferred to the hot blanket and the carrier liquid has evaporated, the resultant melted ink film is moved to the media by direct contact and with virtually no changes. The HP Indigo certification establishes a 3-star ratings system based on the following criteria: adhesion of the ink to the paper, runnability and compatibility with the blanket. HP Indigo certification guarantees high-quality printing and outstanding image rendering results. These digital specific papers are ideal for presentations, announcements, invitations, brochures, dividers, over-covers, press kits - the most rigid sheets are also suitable for packaging applications such as folding boxes or paper bags. The HP Indigo certified papers come in different sizes, formats, grammages, finish, thicknesses and shades. FSC® environmentally friendly, ECF certified. Compliant with ISO 14001, ISO 9706 and ISO 9002.
