On the principle and application of gold sweeping technology

Gold sweeping technology is widely used in the packaging of cigarettes, wine, pharmaceuticals, cosmetics, and premium food products, as well as in the printing of greeting cards, invitations, and calendars. This technique significantly enhances the visual appeal and perceived value of the products. In the 1990s, China began to develop this technology, with advanced regions like Guangdong introducing gold sweeping machines primarily for cigarette and medicine packaging. As packaging standards continue to evolve, gold sweeping technology is expected to see even greater growth. One of the effective methods for enhancing the appearance of product packaging is achieving an imitation gold effect. Common techniques include gold ink printing, matte printing, bronzing, and gold sweeping. Each method has its own unique features. In this article, we will focus on gold sweeping technology. What is Gold Sweeping Technology? Gold sweeping involves applying special metal powder to specific areas of printed materials or packaging using a specialized process to create a metallic sheen. This technique produces realistic metal textures with high gloss, fine details, and accurate overprint. It's particularly popular for its ability to enhance the visual impact of luxury items. Applications of Gold Sweeping Technology Gold sweeping is extensively used in the packaging of high-end products such as cigarettes, wines, medicines, cosmetics, and premium foods. It's also commonly found in the production of greeting cards, invitations, and calendars. In the 1990s, China started adopting this technology, especially in regions known for their advanced packaging and printing industries. With increasing demand for more sophisticated packaging, gold sweeping is set to grow further. How Does the Gold Sweeping Process Work? The gold sweeping process is relatively straightforward. Printed sheets are placed on a single or double-color offset press, where a layer of adhesive is applied to the areas that require gold. The sheets are then fed into the gold sweeping machine, where gold powder is evenly distributed and adhered to the surface. After polishing and knocking, the final result is achieved. Modern gold sweeping machines, such as those produced by Jazz in Germany, consist of several key components: a paper feeding system, coating unit, polishing mechanism, cleaning system, and paper collection unit. These machines can handle various paper types and sizes, with speeds reaching up to 8,000 sheets per hour. They are often connected to offset presses, allowing for efficient online gold sweeping operations when combined with UV drying systems. Advantages and Disadvantages of Gold Sweeping Compared to other gold-imitation techniques like Indian gold or matte printing, gold sweeping offers a more realistic metallic texture and better gloss. It’s also cost-effective and versatile, suitable for both small and large areas. Additionally, gold sweeping provides a unique anti-counterfeiting feature due to its distinct visual effect. However, it has some limitations. For instance, it may not achieve the same level of gloss as bronzing in certain cases, and it requires strict environmental control—temperature between 22–25°C and humidity at 50–55%. Common issues include dusting and sticking, often caused by improper moisture levels or insufficient adhesive application. Conclusion Although gold sweeping technology has some drawbacks, its advantages in terms of anti-counterfeiting, visual appeal, and cost-effectiveness make it a valuable tool in the packaging industry. While currently used by only a few manufacturers in China, the continuous improvement of gold powder technology and the integration with other methods like bronzing and screen printing are likely to expand its applications. In the future, gold sweeping is expected to play a significant role in the packaging of luxury goods such as tobacco, wine, and high-end pharmaceuticals.
