Here is an image of my 168.005 dome dial. circa 67/68 (probably not a million miles away in age from the 168.018 you posted)

Absolutely legit and makes your Cs & Fs look positively conformist 😉
Sometimes I think people expect modern manufacturing standards from vintage watches.
Dial printing in the plastic crystal era was not an exact science.
And certainly companies like Omega never expected their customers to inspect each letter of every word for crispness and thickness consistency. The dials were probably quickly inspected with a low power loupe during production, checking for smears, or blobs of ink, and that’s about it.
