As I discussed in this article elsewhere on this website, comic book lettering is increasingly being done by computer and not by hand. DC Comics is presently setting up an in-house department that may wind up lettering all their books there and via Photoshop.
The debate on whether computer lettering is better than or even as good as hand lettering is becoming largely moot. For good or ill — and I think it's a little of both — computer lettering has won. Discussing a return to hand lettering is about as practical as arguing that the motion picture industry should ditch sound and go back to making silent pictures. There will be hand lettering in comics in the future (we're going to keep doing Groo that way), just as there are moments in movies when no one talks. But neither will ever be the norm again.
The leaders in the computer lettering field are Richard Starkings and the guys over at Comicraft. You can go to their Balloon Tales website and find out all sorts of valuable information on how it's done and how to do it, plus they have a major "how to" book coming out next month. Then you can go to this website and purchase some of their delightful fonts. You can also obtain some fine fonts (some of them, free!) and tutelage over at Nate Piekos' Blambot Studios.
As I said, I have mixed feelings about the move away from hand-lettering. I think everyone in comics does, and they'd be only more mixed if there were more great practitioners of the art around. But I think we have to face the fact that computer lettering is no longer a new way of doing it. It's the way.
