When you are looking at the preview and you see a typo, fix it right away and then go back and proofread the preview again. You do this again and again until it’s all fixed.
Trying to remember all the typos you want to fix so you can save time by fixing them in one trip is what causes them to appear carved in stone forever.
Exactly what I do. And I still miss one now and then.
