[Technical field]
[0001] The invention relates to the technical field of printing equipment, in particular to a printing device for producing food packaging boxes. [Background technology]
[0002] Printing is a technology that uses processes such as plate making, inking, and pressurization to transfer ink from original manuscripts such as text, pictures, and photos to the surface of materials such as paper, fabric, and leather, and to replicate the contents of the original manuscripts in batches. In a simple sense, printing is a process that uses printing plates or other means to transfer the graphic information on the original manuscript to the printing material. In order for consumers to understand the food without opening the packaging, the product name, photos, and trademarks must be printed on the food packaging.
