The mailer box is sturdy and stylish, and it is an ideal packaging solution for Ecommerce delivery box.There are two main printing methods used on the mailer boxes: Offset printing and silk printing.
Offset Printing
Offset printing is an indirect printing method; it prints the graphic to paper first and then glues the printed paper on the corrugated cardboard. The offset printing machine has excellent printing performance. It can print up to 7 Pantone colors at a time.
There are also two printing types of the offset printing
- Pantone Printing
- CMYK printing
Pantone Matching System (PMS)
The color of Pantone printing is very uniform, and the printing stability is very good. If the mailbox is designed as a large area of monochrome or two-color, Pantone printing is the best choice to ensure that the colors of different printing batches are uniform and that multiple colors will not interfere with each other.
CMYK Printing
The printing of CMYK is different from that of Pantone. CMYK creates designs from many dots. This printing method can well solve the printing of patterns with complex backgrounds and gradient effects.
