    Some RGB files produce no Black Separation


      We are a commercial printer. I've seen pages on many jobs recently where RGB images are converting to CMYK using SWOP profile, but no black sep information is present. The image separates into 3 colors only. When exporting from ID, we suggest leaving color unchanged, since our RIP has always done a great job of converting RGB to CMYK. Has anything changed in CS5 that would cause this?
