Overprinting will cause solderballs. You can print with a 1 mil reduction (or even 1:1) with the 0402 pad as that will maximize solder between the contact area.

Subject: [TN] 0603 on 0402 pads
Has anyone placed 0603 passives on 0402 pads? There isn't much overlap,
and I'd expect placement would be critical. Does one need to overprint the
paste?
