Digital printing is a printing technology that directly outputs digital files onto media such as paper, plastic, and fabric through printing equipment controlled by a computer. It breaks through the limitations of the cumbersome processes of traditional printing, such as plate making and imposition. Through digital signal processing and technologies like inkjet and electrostatic imaging, it achieves a fast and flexible printing process. In today's era of rapid information dissemination and growing personalized demands, digital printing technology has been widely applied and developed.
