If you're producing GelatoCreate's orders, you'll notice that the plates are organized in a way to facilitate the production line in your facility. After printing and cutting, plates should be consolidated according to the indicated stack order. Here is a guide on understanding cover sheet colors:
Beige: single items in package
Green: multiple items in package > ordered by box # with details on back of cover sheets for easier grouping
Orange: products to be bound
Red: reprints > prioritize for fulfillment
