Ink adhesion performance is the core guarantee for durable printing quality of color packaging paper, advertising printing paper and book paper. Insufficient ink adhesion easily causes common printing defects such as ink peeling, ink rubbing off, pattern fading and partial ink shedding in daily use and post-processing. The root causes include unbalanced paper surface tension, insufficient surface micro-roughness, residual sizing agent barrier layer and inactive surface fiber molecules. Most paper surfaces are too smooth or excessively sized, forming a dense isolation layer that prevents ink molecules from penetrating and bonding firmly. Traditional printing performance optimization only adjusts surface sizing dosage, which cannot form effective ink anchoring points and often leads to reduced water resistance while improving ink adhesion. This long-standing technical contradiction affects the dual improvement of paper waterproof performance and printing durability. Shandong Ludao Energy Technology Co., Ltd. launches professional ink adhesion balancing solutions. By moderately activating paper surface molecular activity and building micro anchor structures for ink bonding, we strengthen the combination fastness between ink and paper substrate. The solution does not damage paper water resistance and surface flatness, effectively avoids ink peeling and rubbing defects, improves printing pattern durability and wear resistance, and upgrades the comprehensive quality of color printed paper products.
