This high-quality 190 g/m commercial proofing medium was jointly developed by EPSON and DuPont. DuPont is the manufacturer of Cromalin , the de facto industry standard for analogue proofing paper. It bears the Cromalin , DesignerProofwater mark and is the ideal medium for the last phase of digital proofing (before the film), in which high quality and exact colour fastness are of prime importance. The various coating types (matt, publication, and glossy) reflect the diversity of the alternative media available for the last printing process.
