FAQ
Both are β-phase copper phthalocyanine with virtually identical hue angle and performance. PB 15:4 is a non-flocculating (NF) grade surface-treated to resist crystal growth and flocculation in high-polarity solvent systems. PB 15:3 is preferred for solvent-free UV systems and mineral oil-based offset inks; PB 15:4 is typically chosen for solvent-based and waterborne flexo/gravure inks.
