Upon export to a Photoshop RGB file or an internal conversion in AI, my CMYK black takes on an RGB value of 35/31/32. I've tried many combinations of color settings, none seem to help the issue. I'm using the CS4 Bridge North American General Purpose 2 (synced) profile. My 'appearance of black' settings are display as rich black, output accurately. Most of my files will end up as spot color separations, so color profiling is not a major concern (should it be?). The raster files are also separated as spot colors for t-shirt printing 99% of the time- although I do some CMYK work on occasion. This issue seemed to arise with the CS versions of Illustrator (CS2 I think). Although I've created a spot black swatch for new files with 0/0/0 RGB values, many of my old files were created using 100% CMYK Black, which converts to the 35/31/32 RGB as mentioned above. Thanks in advance for any help, this issue eats up a lot of time converting the weak RGB blacks to a solid black. Ethan
