Graphic technology – Process control for the production of half-tone colour separations, proof and production prints, Part 1: Parameters and measurement methods
AS ISO 12647.1:2023 identically adopts ISO 12647 1:2013, which defines and explains the minimum set of primary process control parameters required to uniquely specify the visual characteristics and related technical properties of process-specific production prints and process-independent simulations of fully characterized printing conditions
