And what did you end up finding out. Is it okay for the silk screen to overlap the soldering pads, or holes for that matter?
I am currently putting the finishing touches to a project which I am very soon going to design the prototype PCB’s for. But I know from past projects, that some of the footprints I need, have parts of the silk screen running over solder pads and holes, since that doesn’t matter at the manufacturers I normally have used. So if it isn’t allowed in designs for manufacturing at SeeedStudio I might as well redesign the footprints before making or sending the PCB design, instead of getting it turned down.
So my question is: Is it okay for an silk screen line to cross a soldering pad or a hole? 
Best regards and thanks in advance for your answer
