What is the process called Piezography for Black and White Photography?
It is a commercial printing process for black and white photography invented by Jon Cone in the year 2000. The Cone Piezography Inks are special greyscale-only inks, made specifically for black and white photography printing. Instead of using black ink and color inks, the Cone inks use a series of black inks of varying intensity that allow for an extremely long tonal range and very subtle renderings of tone. The inks are carbon based, so they are some of the longest lasting inks available.
