That is the whole point of using PDF/X-3: It allows the content to be mixed and leaves the CMYK-conversion to the RIP/printer. >From the Wikipedia article on PDF/X: "For example, in PDF/X-1a all fonts need to be embedded and all images need to be CMYK or spot colors. PDF/X-3 accepts calibrated RGB and CIELAB colors, while retaining most of the other restrictions of PDF/X-1a." If your printer requests a "CMYK only PDF/X-3" you should ask him why (and explain to him that it seems contradictory). It seems more as if what he wants is PDF/X-1a. /Peter
