There are several printing methods for cardboard boxes, including:
- Flexographic Printing: This is the most commonly used printing method for corrugated cardboard boxes. It uses flexible printing plates made of rubber or polymer, which are wrapped around a printing cylinder. The ink is transferred from the plates to the cardboard surface, creating a printed image.
- Lithographic Printing: This printing method is best suited for high-quality printing on smooth cardboard surfaces. It involves the use of printing plates made of aluminum, which are chemically treated to create the image. The plates are then mounted on a cylinder, and the ink is transferred from the plates to the cardboard surface.
- Digital Printing: This method involves printing directly onto the cardboard surface using a digital printer. It is ideal for short runs and custom designs, as it allows for easy customization and quick turnaround times.
- Screen Printing: This method involves the use of a mesh screen with a stencil of the desired image. The ink is forced through the screen and onto the cardboard surface, creating the printed image. Screen printing is best suited for large, bold designs.
- Gravure Printing: This method is best suited for high-volume printing of simple designs. It involves engraving the design onto a cylinder, which is then used to transfer ink to the cardboard surface.
