What kind of problems will water-based ink printing cardboard boxes encounter
Date: Jul 17 2023 From: Star Color
Water-based ink printing on cardboard boxes may encounter several problems, including:
1.Absorption and Bleeding: Cardboard is porous, which means it can absorb water-based ink quickly. This can lead to ink bleeding, where the ink spreads and blurs on the surface, causing the printed image or text to appear fuzzy or distorted.
2.Smudging and Smearing: Water-based inks take longer to dry compared to solvent-based inks. If the ink doesn't dry completely before handling or stacking the cardboard boxes, it can smudge or smear, damaging the printed design or causing ink transfer to other surfaces.
3.Color Intensity and Vibrancy: Water-based inks may have limitations when it comes to achieving intense and vibrant colors. The porous nature of cardboard can absorb some of the ink, resulting in colors appearing dull or faded.
4.Adhesion Issues: Water-based inks might have difficulty adhering to certain types of cardboard surfaces. If the ink does not adhere properly, it can lead to poor print quality, uneven coverage, or adhesion failure, causing the ink to peel off or rub away easily.
5.Durability and Water Resistance: Compared to solvent-based inks or other printing methods like UV-curable inks, water-based inks are generally less durable and less water-resistant. This means that exposure to moisture or water can cause the ink to run, fade, or lose its integrity over time.
6.Dry Time and Production Speed: Water-based inks typically require longer drying times, which can slow down the printing process and reduce overall production speed. This can be a challenge for high-volume printing operations that require fast turnaround times.
To overcome these problems, proper ink formulation, optimized printing techniques, and appropriate surface treatment of the cardboard boxes can be implemented. Additionally, selecting suitable ink additives, coatings, or sealants can improve adhesion, color vibrancy, and water resistance.
