do piezo ink sets have a higher dmax then Epson advanced black and white?

ex. special edition k7 ink set?


#2

What dMax are you getting with ABW and on what paper?
dMax is paper dependent.

ABW will make dMax quite lighter than RGB value 0 pixels. It can not differentiate between the lowest shadow detail values and produces dMax easily.

Piezography only prints dMax at RGB value 0 so that it can print the tonal separation between all 256 values. RGB value 1 is actually lighter than 0 with K7.

You can not easily find your dMax in LR because it is a proxie you are looking at and the actual processing often differs from the histogram - so move the image out of proxie state in LR to Photoshop and then find out if you really have dMax pixels or not.

Complex answer to easy question…


#3

complex for sure.

so on photo rag paper from the site it says piezo can print at dmax of 1.65, what does Epson advanced b&w come in at on photo rag?


#4

Epson comes in lower…

Epson ABW hits about 1.55 - 1.58 on Photo Rag
QTR driven ABW (with the 3 K’s) hits about 1.64 - 1.65
