Die-lines can be sent to us in quite a few different file types including: .ard, .dxf, .dwg, .eps, .pdf, and .ai. If you have a different file type not listed, there is a good chance we will still be able to work with it. When sending .pdf’s make sure the die-lines are vector elements and not rasterized. It is also good practice to include a few dimensions in the file, this will help us to insure the export / import process did accidently scale the die-lines.
