There is another aspect to this.

If the note is there as Ted suggests, it may be because the designer doesn't
have access, or the funds, to have CAM software that clips the silk off
solderable pads.

The design software I use doesn't flag that as an error (more's the pity).
It has to go through CAM data to find that.

Subject: Re: [TN] Silkscreen on pads


        If the customer had silk on the pads in the art work and a
manufacturing note stating, "There shall be no silk screen on exposed
copper", then bare board supplier needs to take responsibility for the
problem. The bare board supplier should have contacted the customer and said
there is a problem, the art work doesn't match the fabrication notes. That's
why fabrication notes need to follow the art work to help flag the
inconsistencies or errors that tend to slip through the cracks. Lets say the
board was produced some place else and the old board supplier caught it
fixed it and didn't say a word, never happens right? The customer would have
never known that there was a problem, how do you fix a problem you don't
know exists?
