Has anyone observed print fading occurring on aluminum beverage cans once in the marketplace? Is this typically caused by UV light exposure from fluorescent bulbs in warehouse and/or cold box storage? Is this caused by inadequate UV protective overcoat application during the can printing process?

    Yes, inadequate UV protection, and/or high sunlight or very bright UV exposure can hasten the dulling of colors. Inadequate UV curing after printing can also cause problems. UV resistant inks can help. Florescent pigments tend to have a short life, regardless of how strong the UV protection is. – 13ruce Jan 28 at 16:57
