A couple of issues going on here. First, the Black ink is on the 90 degree angle on the iGen. Test it out, print a 50% black in a thin font around 8 - 10 point. Your vertical lines in the T, I, N, etc will be gone in most of the characters. Lastly, grey can separate into C,M,Y with little to no K value. The Cyan angle prints the most of the type character so it looks more Cyan.
