Folders are printed and unglued fold-over card stock packaging. Imagine taking a big piece of card stock and folding it in half and putting a record inside — that’s a “folder”.
Inserts are printed slip-ins for packaging. They’re like printed sheets that sit in a poly bag and act like cover artwork for your record.
12 inch folders are printed on 15 point glossy stock and you have the option of printing 1/0 (one colour/one side), 1/1 (one colour/both sides), 4/0 (full colour/one side), or 4/4 (full colour/both sides). 7 inch folders are printed on 10 point stock and can be printed the same way.
