One file, six plates

Open the export and you find six separations. Four process inks, converted with the output intent the printer named rather than with a guess. One spot ink, set to overprint, because that is what a brand colour is on a press. One cut contour, on a plate of its own, so the cutter knows where to cut without a phone call.

None of that is visible on screen, and all of it is the difference between a file that goes straight on press and a file that comes back.

Consumer design software hands you an export and wishes you luck. The gap gets filled by a prepress operator fixing your artwork, and you pay for that either in money or in a week. Closing it is unglamorous work and it is the whole reason the product is worth using.
