The default CMYK black has the values 0,0,0,100 with the 100 being black K color, this is actually not a black but a dark grey (and this is why you use a rich black when printing). So when Illustrator tries to render the gradient it turns grey before fading to red. Now our matched black is a red black since we cranked up the Magenta and Yellow values, thus it renders smoothly from red to black. To not get confused about what black you're using make sure Illustrator is set to display all blacks accurately in the preferences.

| Aug 16, 2014 at 4:03 | comment | added | Scott | Like I posted. "skirting" :) An ink limit of 300 or 310-320 is absolutely possible. It varies based on print provider. In my experience 290 is more common and 300 is pushing the maximum. But again, that's just the print providers I work with. | |
