Dielines are usually created by the packaging designers. They can also be created with die-cutters or a printer. Dielines are used in many types of packaging, not just boxes. From simple folders with pockets to complex packaging, dielines make it possible to cut and fold to create the final product. Dielines are made up of five types of lines:
•Dotted perforation lines
•Cut lines
•Fold lines
•Bleed
•Glue
•Cut lines
•Fold lines
•Bleed
•Glue
When your packaging design goes to be printed, these dielines guide the machine toward making the proper cuts and perforations so that the package can be folded. Since these two things are separate “chunks” of information that the printer receives, the perforation lines and the cutting lines will appear on different layers and in different colors. This allows the printer to know what to trim and what must be folded separately during the die-cutting process. In addition, safety lines and bleed lines are included to ensure that all artwork does not exceed or “bleed” beyond the cut or fold line. These specific processes don’t happen at one time — rather, the printer takes care of the perforation process in one stage, and the cutting in another.
