Abstract
This study aims to compare the printability, optical, and mechanical properties of two types of coated papers: Magno Satin (MS) and Art Carton (AC). The analysis was conducted by evaluating physical, optical, and mechanical characteristics, including grammage, thickness, bulk, brightness, opacity, tensile properties, tearing strength, and printability using offset ink. Printability tests involved measuring optical density, CIE L*a*b* values, hue error, and grayness, with varying ink film thicknesses from 0.8 to 9.6 microns. The results indicate that MS provides higher brightness and optical density, making it ideal for vibrant, high-quality printing. MS also exhibits higher stiffness and tensile strength, making it suitable for applications requiring rigidity and stability, such as brochures and promotional materials. In contrast, AC has greater tear strength, tensile energy absorption, and elongation, which make it advantageous for packaging applications due to its robustness and flexibility. The optimal ink film thickness for both papers was determined to be around 8.0 microns, beyond which the benefits in terms of optical density become minimal, and over-inking issues such as increased hue error and grayness may arise, affecting print quality. These findings highlight that while MS excels in providing superior color vibrancy and detail, AC is better suited for applications requiring durability and high tear resistance. Thus, selecting the appropriate paper type based on the specific requirements of the printed product is crucial for optimizing both print quality and material efficiency.
