On a 1304 I use 540x720, 6 pass, fine and wave 2 for intermediate vinyl with very good results. We do a large amount of 40"x40" window posters monthly at this setting.
Speed vs quality is just about right for these jobs. The graphics are mixed vector, gradients, bitmaps and text eps files.
I use 720x720 4 pass for banners on matte 13oz on the same printer. Gets full 50" x 10' banners out quickly with no visible banding.
Trying to get similar profiles set up for a 1624 but have not hit the same sweet spot just yet.
