Maxie , What base white are you running? The epic quick has been a game changer here as far as the hand with our large retail clients. Also, With all the supernice printable inks available why are you struggling with m3. Again not known for its soft hand, prinability. That ink is a long bodied product.
160 Base- sharp 70/90/70 to clear the screen.. I would consider the epic quick
230-305 all over print colors- even using the M3
