I’m slowly diving into un-replied posts that were buried by our previous forum software a few years back.
If a paper is offset coated it will actually not dry well because it is meant for high compression halftoned ink. Inkjet prints put a lot more ink on than offset. Often these papers say they work for “digital printing” but this just means either digital offset or laser and not inkjet. I think you need a paper like HP ColorLok or similar.
