Running Ver 13 here, along with SignStation but this a distinctly Cockpit bug. I just finished a ganged postcard job, all imposed and ready to plate when I noticed one of the cards has an element on the front that was left as a Pantone, supposed to run 4/2 so I went back to the InDesign, convert the offending element to 4c. When I re-RIP it, Prinect converts the
whole job to 4c, including the backs which were K & another PMS.
This happens intermittently, and the only solution is to destroy the job & redo it completely.
