To be fair, those guys have been around forever. So it’s probably just the latter (they advise CMYK but reluctantly do the pre-press job themselves.)
They do provide a proof as part of the project, but the price is prohibitive for the volume I’m doing (~30 calendars at 14$CAD/copy is around 500$ with tax!). So I ended up buying my own paper and will print with a friend who has connections inside a school with good printers… This brought me into a whole other universe of actually finding good cover paper, but that’s a whole other thread in itself.
