I have a pdf supplied by customer to which I have added two logos. Pdf was supplied as spot colour but we now need to print in CMYK. Have added logos in Illustrator. . . then dropped file into Indesign to send to press. (Do this all the time!) The spot colour is coming down as the 'wrong' CMYK split and the black is also coming down as CMYK instead of black. I have reopened the file and changed the 'spot' to the 'right mix' and the black to black & resaved. But it keeps changing back to the wrong mix and CMYK black. I must be doing something obvious wrong. . .but I can't see it.
