1. Design: The first step in product packaging printing is design, which includes considerations such as the packaging's shape, size, color, pattern, and text. Designers need to develop the optimal packaging design based on the product's characteristics and market demand.
2. Platemaking: Platemaking is the process of converting the designer's designs, such as patterns and text, into a printing plate. Platemaking can be performed manually or by computer. Manual platemaking requires experienced technicians, while computer platemaking can be performed using computer software.
3. Printing: Printing is the process of applying the prepared patterns and text onto the packaging material. Printing methods include letterpress, gravure, offset, and flexographic printing. Different printing methods are suitable for different packaging materials and printing requirements.
4. Post-processing: After printing, post-processing is required, including lamination, hot stamping, embossing, and die-cutting. These processes enhance the packaging's texture and aesthetics, while also improving its waterproof, moisture-proof, and anti-oxidation properties.
5. Inspection: After printing, inspection is required to ensure that the printing quality meets requirements. Inspection includes appearance inspection, size inspection, color difference inspection and other aspects.
