Commonly Used Printing Terms

Have you ever had a conversation with your print vendor and been left completely confused by the end? You are probably not alone. Us here in the printing industry tend to talk in printer lingo. Since we live, eat, and breathe printing, it comes as second nature to us and rolls off the tongue.

To compensate for all those times we should have explained things in layman’s terms, below you will find a list of common printer terminology.  After reading this, you will be able to speak the language of printers!
