I received the HD ink and have started testing with the HD PK Master curve. My i1 is old and the readings may not be accurate but I think they are consistent and should indicate relative values. The HD PK Masters curve works very well with the HD ink on Jon Cone type 5. It brings Dmax to around L*4.4 from L*5.8 (and maintains a barely perceivable threshold at level 2. The Museo silver rag however is too dense for this curve, its Dmax is 2.5 and the first barely visible line is around level 16.
I am assuming that the piezo pro software will allow me to pull back the black ink, (or shade 2&3) to lower the threshold. Is this right?
Could I also hear your thoughts on applying a traditional (colour managed) fix to this problem? If I were to apply a black point target adjustment to the file, effectively reassigning the data to maintain DMax at L*2.5 and bring the threshold to level 2 or 3, what would I be compromising when compared to a proper piezo pro curve relinearization?
