Paper Lesson

February 13, 2012 / Updated: February 13, 2012 / Lena Shore

Over the weekend I was cleaning out my office and found this great little cheat sheet I created years ago for understanding paper types as explained by one of my printing mentors, Jon Anderson.

Paper weight

The weight of a paper is determined by how much a ream (500 sheets) weighs in the basis size. The basis size is the size it is produced at the mill.
