Sorry to post to an old thread, but this info might help.
"Flat Top Dots" aren't anything new or surprising. You basically had flat top dots with analog film and plates, because when the UV exposure happened the film was acting as an oxygen barrier. Flat top dots were something that you had to give up when going to a laser-ablative mask CTP system (LAMS). Newer systems like the Kodak NX and the high-cost options on other systems really are attempting to get you back to what you already had with analog.
The big benefit of flat top dots is they're a LOT more forgiving on press - they don't grow or shrink as the impression strength changes. They're also much better able to hold fine detail because the dots have a stronger shoulder. In "ideal" printing conditions you probably won't see much difference - but who runs in ideal conditions all the time?
I have a ton of other info if you need it. I used to work for Kodak, and now manage the NA market for DigiFlex - so I'm more than glad to share my knowledge and help out (without the high-pressure sales, if you're just looking for info!).
