Objectification sounds like a pretty odd translation to me. It's worth noting that the antonym to papanca is nippapanca, which is understood to be synonymous with nibbana. Therefore, whatever papanca is, it is not done by arahants, hence the definition I gave earlier, stipulating delusion as an inherent component.
The Buddha came up with some cracking similes though, presumably derived from his imagination, requiring some degree of conceptual objectification... yet, it was imagination that was embued with and characterised by nippapanca rather than papanca.
