Profinishing ink pinlines

Hey all, Does anyone ever not gloss after pinlining with ink or resin? The local factory in town uses what they call ‘profinish’ as a last coat after sanding, rather than glossing. When pinlining, they first spray the pinline with an acrylic spray, then profinsh (by simply rubbing on) after it dries. I have yet to see the results of this and was wondering if anyone has any advice.
