The printing of tinplate sheets can involve several techniques, including offset printing, screen printing, and digital printing. Offset printing is widely favored for its ability to produce high-quality images with intricate details, making it ideal for branding and promotional purposes. Screen printing, while more traditional, allows for vibrant colors and is often used for larger runs of consistent designs. Digital printing, on the other hand, is increasingly popular due to its flexibility and efficiency, allowing for short runs and quick turnaround times without sacrificing quality.
