So how would you do a gradient that DIDN'T blend the colors?
If you want to go from solid red to some tint of red, and from that to some tint of black and from that to solid black, add two new stops in the middle of the gradient with the tint values. Set them so they are right next to or on top of each other.
Thank you Peter for getting back to me. Yes, I understand that a gradient has to have a blend.
It's hard to explain, but my sample I sent appears to have grey or brown blends rather than true black. (looks washed out)
I know that if I was to do the same red-black gradient in PhotoShop the result would look very different.
Am I 'out-to-lunch' here?
I don't believe you are the first to bring up the difference between Photoshop and ID. Are thes spot colors, CMYK, or RGB? What's your transparency blend space set for?
In addition to making your black with magenta and yellow, the Appearance of Black Preference and your doc's CMYK profile & Color Settings will affect the blend's preview.
If the preference is set to Display Blacks Accurately, your preview will show what happens on an offset press when you make different black mixes. So, here 0|100|100|100 shows a redish brown black (left) but 65|50|50|100 (right) is a neutral rich black—center is something in between 40|85|40|100:
If your preference is Display All Blacks as Rich Black black mixes are not soft proofed accurately:
