I am looking for high-quality black ink specifically designed for product labeling. It's essential that the ink provides excellent adhesion to various surfaces and maintains clarity over time, as the labels need to withstand different environmental conditions. Additionally, I'm interested in ink that dries quickly to streamline our labeling process. Could you provide information on your available formulas, including details about color stability, compatibility with different materials, and any eco-friendly options? Also, please include your minimum order quantities and pricing structure. Understanding your lead times would help us plan our production schedules effectively. Looking forward to your prompt response!
