Please change the default behavior when converting a file from RGB color space to CMYK color space to make RGB black convert to 100% black. Currently and for years, Illustrator converts it to a rich black, with high values in each ink. It's very common to have to take artwork created in RGB and covert it to CMYK for print, and the default conversion for black is never usable. Please make it practical and have 0,0,0, RGB black convert to Cyan 0, Magenta 0, Yellow 0, Black 100.
