How much do you know about printing for packaging boxes? Do you know how the colorful colors on the packaging paper boxes were printed? Let me explain some basic printing knowledge to you, I believe that will give you some helps！

Generally speaking, the most commonly used is offset printing. It's used for custom packaging boxes suchasmagnetic box,foldable gift box,corrugated mailer box and so on.

Offset printing — also known as lithography — is another familiar printing process. It involves a machine that uses the placement of ink onto an actual thin, flexible, printing plate that is held in place by a plate cylinder.Lithography is also called offset printing because the ink is never directly conveyed onto the paper.

Once the plate is inked, the prepared image is transferred to the rubber cylinder that holds the rubber blanket. The final step involves pushing it through the impression cylinder which contains a paper sheet. There are many other smaller cylinders within the lithography machine that are required for it to work properly.
