[QUOTE=Anthony;12871]I need to continue to test it but my first impression is that the difference between the same print on K7 and P2 is really subtle and tiny (but it exists). Slightly “visible” (and “harder” for the P2), in the clear gray. It’s more a “feeling”, when you see the two prints together, than “visible”. Of course it’s only my personal opinion.[/QUOTE]
I’m always interested to hear of other users’ comparisons of K7 and P2. When JeffG and I were switching to P2 we did a number of such comparisons and we simply couldn’t see the difference. You’d expect the difference or adding of removing shade 7 to be in the highlights, and so we looked particularly at high-key images, although given that the entire structure of a P2 curve is different, perhaps differences might not solely be on the highlights. In any event, as far as we could see, the prints were identical.
Do you happen to know whether your curves are linear or not? Our comparisons were using curves that had been relinearised and were both deal linear. If that’s not the case then you’d expect some difference between the K7 & P2 prints simply from differences in linearity. Especially because each K7 curve is supposed to apply for a particular paper across all five inksets, whereas a separate P2 curve was created for each of the inksets. If you’re using unrelinearised stock curves then you’d expect differences from this, and in my experience the P2 curves are generally more linear.
