ECI says the 2013 revision of ISO 12647-2 changed ink aims and tone-value curves for optically brightened papers; FOGRA51/52 come with PSO Coated/Uncoated v3 profiles and require M1 (UV-including D50) measurement for metered proof and print control; FOGRA49/50 cover matt/glossy lamination derived from FOGRA39-era test prints, varnish shifts are smaller and have no standard data set, and FOGRA60 covers metal printing.
