Thanks @joponnes for the Tag & Congrats to @pfm for this great summary.
I really enjoyed how you have shown the Foil Debossement Pattern ! Great Idea !
This is a really good visual guide to understand Parallel & Print Run, if any of you want to follow the white rabbit and learn about the deepest level which are the stock “Stock/PrintRun/Parallel/” I have reverse enginneered the Commodity Code and posted a great summary here 
Good luck to those of you which will be brave enough to make the leap.
Have an awesome day.
