this is a good option, and i've been using it for a long time as well. there are times when it isn't quite enough white ink for me, but i think it's because i'm too picky. the customers like it just fine. i just made an additional production environment for "Black and Dark hi-res" and "Black and Red hi-res" that has the white underbase at 1440x720 and left the cmyk at 1440x720. then i saved it as a new environment so that i can easily choose between the two.
i agree that this should be utilized by all!
