Tinplate printing process: 1. Raw material preparation (tinplate original plate, coating material), 2. Surface treatment (cleaning, chemical treatment), 3. Coating treatment (primer, printing, topcoat), 4. Post-processing process (baking, cooling), 5. Cutting and forming, 6. Packaging and delivery.

Use ink with excellent anti-corrosion performance during the printing process to improve the corrosion resistance of tinplate printed products. Anti-corrosion ink has good chemical corrosion resistance and weather resistance, and can provide long-lasting protection.

At present, tinplate printing mainly uses the following four technologies: offset printing, gravure printing, flexographic printing and screen printing. Each technology has its unique characteristics and advantages and is suitable for different application scenarios.

Tinplate printing usually adopts processes such as offset printing, gravure printing and screen printing. Offset printing is widely used due to its high efficiency and high quality. The cost of monochrome offset printing is approximately between US$0.1 and US$0.3 per square meter.

Improving the production efficiency of tinplate printing requires starting from many aspects such as equipment upgrading, process optimization, personnel training and technological innovation.
