Vent: my coworker said rich black is a myth and now I can't stop thinking about it
We were setting up a 4 color job last Tuesday and she just shrugged and said "just use 100 K, nobody can tell the difference." Now I'm second guessing every dark background I've ever sent to press, has anyone actually gotten called out for flat black vs rich black on a real print run?
Ran into this exact thing about five years ago with a big flat black background on a poster job. Client came back and said the black looked washed out next to the dark blue, and yeah, that was a 100 K flat black that should've been rich. What fixed it for me was just building rich black into my standard setup for large dark areas, something like 60 40 40 100, and keeping 100 K only for small text and thin lines where registration gets messy. Your coworker isn't totally wrong though, on small stuff or cheap stock the difference can be real hard to spot, so it kind of depends on the job. Take this with a grain of salt since every press and paper is different, but I stopped second guessing myself once I made that a habit.
