what is the difference between a page and a panel when talking about folders and booklets?
When referring to inserts, folders and booklets, one panel equals two pages. A ‘single panel insert’ has one page on one side and one on the flip side. A ‘4 page folder’ has two pages on the outside of the folder and two pages on the inside. A ‘booklet’ has multiple pages. The format of pages is often understood by the comparison to the pages of a book when opened with page 2 on the left and page 3 on the right, for example.
