Thanks for yor answer. This is very true.

You set: 50C 50M 50Y 0K

Printer puts eg. too much cyan ink on page, that gets you: 60C 50M 50Y
---> your "grey" is tinted blue!

But by todays standards & quality checks not a problem anymore. And
most commercial printers print 4 colors in one run; the online
printers and newspaper printers have strict color management.
