K values and Luminance values

Hi all.

I am calibrating my digital negatives using PDN for kallitype printing.

I have used the software to arrive at a curve that is very close to linear.

However i notice that the negatives are now less dense, especially compared to my negatives for platinum, The highlights seemed blown out before I linearized, now they seem too dark despite the curve suggesting everything is good.

So my question is, what luminance values as density on paper should match which K value in photoshop?

Like what would the ideal luminance value on the page be for 90% k in photoshop for example.

Just trying to get my head around it so I know what the goal is.

Ideally the image in photoshop should have similar tones when printed in different processes right?

Cheers

Are you only looking at the negatives? Because Platinum is a different process and requires different Highlight densities it’s logical that the neg would be less dense for Kallitype. The printed measurement on the screenshot look just fine.
