Hi Everybody,
I have three questions.
1. I can't find a definition of "pure" black on the internet. See color tab in print dialog.Is it (0, 0, 0, 100) or (92, 79, 62, 98) (rich black).
2. What does the check box do. I have not seen any difference when converting sRGB to CMYK if the box is checked off or not.
3. Just to save the cost of colored ink, is there a way to get a photo to print sRGB black as (0, 0, 0, 100) on a consumer level printer. I can live without rich black.

Phil your RGB images that print to CMYK devices will be converted to the device media profile with that profiles predetermined TIC limit, they may assume a source RGB space or honor the embedded RGB profile. In short no rich black.
The photographic reproductions will have one of two processes applied. They will assume a specific (generally sRGB) RGB source space and then convert to the device space. In general with photographic device it's another RGB color space. Or they will honor your embedded RGB ICC profile and convert to the device RGB profile, again no rich black as it does not exist in the RGB world.
In practice rich black is never used for photographic reproduction. However a designer my decide that they need to artistically enhance an image.
