Digital BW, The Print

Hi Charles,

I have the very same setup as you do. I'm using a Mac with the 
1280 and nomorecarts, VM inks.

When printing with Paul's MW curve, I also had the identical 
stepwedge issue with the gray "inversion". The problem was 
less noticed with the neutral and cool curve.

After many test wedge prints and adjustments to the RGB curve 
channel, I lessened the flatness somewhat. Never to the level I 
wanted but close.

Now, I've just tried Tyler's new curves (on a Mac) and side by 
side prints (old curves and Tyler's plat or crv 09) show that the 
flat spot is gone. They look better and print beautifully. And I'm 
using them on a Mac.

Anyway, not a real solution for you here, I guess but it is 
interesting that two identical setups produce the very same 
wedge look.
