Same as Kaydreamer, but I also will spellcheck in Photoshop if a word stops looking like a word (which...when you've stared at a page for hours...sometimes words stop making sense XD).
I also will check words with an online dictionary sometimes...and other times my awesome readers will say "hey, I don't think you meant that."Legit, on Comic Fury I have a wonderful reader who caught that I'd said "wonton" instead of "wanton." And while I love wontons, that is not what I meant to say XD XD And "yolk" instead of "yoke." I dunno what my deal with food is...
**Before I go to print, I also do a thorough edit, have my partner edit it, and then I edit what he edits. But that doesn't help if you're the only person available to do that. The point is, before I invest money in printing, I have at least a second pair of eyes I trust read it (and even then, stuff can get missed -_-)
