Thanks for the link, I know the acv method or the Point List one, 
they are similar, just a question of habit. I'm sure Walker got 
something out of it. But he had something to start with. On glossy 
media Jon shared a graph, and this did do either. So I have to make 
it differently. The easiest I presume would be to start by a 1440 res 
vs 2880, it's more forgiving. I'll do that when all else has failed.

I thought about that. But I don't see practically how you do that, I 
mean the temporary assignment.

As I said you can swap a combination of ink for another one to output 
the same density, the darker in the ramp the more you lose some 
smoothness to allow GO in. However, I start wondering whether GO here 
is not simply meant to be a proper overcoating vs an additional 
channel at the printing stage.
