Hi Biff, many thanks. Completely get that, and all the print workflow is well bedded in over a few years now, including turning off the soft proof layer before printing. I know that one's caught many people out! Thing is, it worked perfectly the day before Big Sur upgrade, and now not. It seems not to be registering the custom profiles at all when it comes to instructing the printer. I can get an approximation using sRBG or Adobe, but clearly that does not match the paper characteristics in the way that a custom calibrated paper profile does. Anyway, I think I'll just stick with PS for now - hopefully affinity read this and will look into it, with an update at some point
