Inks & Coatings
In this series, learners will explore how the physical and chemical properties of inks and coatings—such as viscosity, adhesion, drying behavior, and VOC content—directly influence print quality, durability, and regulatory compliance. They will also learn how color systems like CMYK, Pantone, and RGB affect accuracy and consistency in packaging, and how coatings can alter color perception. The lesson introduces the major ink and coating types used in the industry, including water-based, UV, solvent-based, gloss, matte, and specialty finishes, emphasizing how each impacts appearance and performance. By understanding these fundamentals, learners will be better equipped to select appropriate materials and ensure high-quality, consistent results in paperboard packaging.
