👉 Hallmarking is a process used in the manufacturing industry where a company uses its own unique, distinctive, or trademarked logo, colors, and designs on products to distinguish them from those of competitors. This can include packaging materials, labels, advertisements, and other marketing materials that are printed with the hallmark mark. Hallmarks have been used for centuries as a way to differentiate products and companies, and they continue to be an important part of many industries today.
