Lets say you have taken some photos, clean processed them in camera raw, made them into masterpieces in photoshop and are using them in a printed brochure. You have the clean processed raw file, master srgb .psd file. You convert them to the CMYK profile provided by the printer, then which file format do you save them to place them in Indesign for the brochure? I have read many printers websites and they want CMYK tif files. Advice appreciated.
