ISO 12647 (International Organization for Standardization), a foundational standard in color management and print quality, emphasizes key quality control parameters in offset printing. These parameters include the required L*a*b* values for printing inks in their solid state, Dot Gain Curves for various paper types, and acceptable tolerances for Color Density. The standard aims to create an objective reference for matching the printed color to the design data (Proof), ensuring reproducibility throughout a print run and consistency across different printing presses.
