Apparently you can tell (apart from the obvious inkjet with a knackered print head) because the earlier run with decent quality print had art underneath a starpost on the left, but the subsequent run(s) had the now trademark "we can't be ****d to fix pooling or chipping, since people keep buying this **** anyway, so we'll have have an unsightly black ring under posts instead, so when it does chip it's not so obvious or they won't cry so much" school of thought.
