So I finally got around to linearizing an existing p800 paper curve by 1) taking an existing p800 paper curve, 2) removing the linearization part, 3) printing a test ramp through QTR with the linearization-less resulting paper profile, 4) measuring it with my densiometer, 5) feeding that to the linearize app, 6) putting the result into the paper profile, 7) reprinting the ramp to verify the results. Unfortunately, when I am remeasuring the linearized profile ramp am seeing that it is not all that linear---the curve is decently linear from step 1 to step 15, but then it starts curving upwards.
So: Is this typical? It seems like I would want to linearize my linearization again.... What does one do in this situation?
Here is the resulting densities, if anyone cares. 0.06-.07 differences in the low densities, .2+ differences in the high densities.
