This was discussed in the Phonogram listserve recently. Apparently, RTI experienced an INTERMITTANT problem with a chemical reaction coming from some of the record sleeves that leaves white marks on the LANDS, not in the GROOVES. After finally figuring out what was causing the problem (apparently a frustrating search because it was so intermittant), they've switched to a 4mil poly sleeve that they believe will cure the problem.
FWIW, I have dozens of RTI pressed LPs and have yet to see this on any of my LPs, which is probably just an indication of how intermittant this is. (I do note that your LPs may or not be pressed by RTI.)
