Please watch this short video which demonstrates the difference between 4/0 and 4/4 printing of a presentation folder.
If you prefer to read, well then here is the simplest way to explain 4/0 vs 4/4:
4/0 means printing one side of a sheet of paper in *4 color process.
4/4 means printing on both sides of a sheet of paper in *4 color process.
We hope this clears up what 4/0 and 4/4 means when it comes to printing.
