After installing the inks on the 9900 I have proceeded to linearize Han Photo Rag. I remapped the original curve found on the piezography curves for K7 and 9900, so that I could bypass the LC, LM and Or channels. I took great care to do so. I checked by printing a calibration 10 ink image, seeing that indeed each shade is in its good place.
What happened puzzled me a bit. I have printed the 256 patches target, measured with the I1pro v2 in M0 mode (single pass). The results are extremely jagged, with many many (many) false values. See results attached.
Interestingly, on the target printed I see no banding, no strange artifacts, and indeed the patches look nice… I guess this kind of wavy behaviour is eventually not easy to spot without measurements, anyway…
On the screen attached, I have kept the smoothing and boost values at 0%, so that you can see it in all its “glory”. The waves remain quite a bit even at 85%. This is even more than I usually got when calibrating Digital Negatives…
I guess something here is wrong. Any idea about what could be the culprit here? Is it normal?
I also see that the channel curves appear very jagged too! However, I started using a curve taken from the Piezography folder (HanPhotoRag K7 9900) and the only thing I did was remapping the channels, as can be seen on the other image attached.
Thanks in advance for your help with this.
