What are the challenges of achieving vibrant colors on matte-finished polypropylene?
Achieving vibrant colors on matte-finished polypropylene presents several challenges due to the material's unique surface properties. The matte texture reduces light reflection, which can dull color appearance and limit saturation. Ink adhesion is another issue, as polypropylene's low surface energy often requires pretreatment or specialized inks for proper bonding. Additionally, the porous nature of matte finishes can absorb ink unevenly, leading to inconsistent color distribution. Printers must carefully select inks, adjust application techniques, and sometimes use additives to enhance vibrancy while maintaining the desired matte effect. These factors make color consistency and brilliance harder to achieve compared to glossy surfaces.
