Corrugated Mailer Box Printing

Cardboard mailer boxes are usually either flexographic or offset printed. Screen printing is also widely used for simply printing text, lines and patterns. Flexographic printing focuses on strong mailboxes and is used for mailboxes when there are no specific printing requirements. Offset printing is usually applied when a high quality printed image is required on the surface of the box.
