Piezography K7 and K6 has the longest dynamic range of any digital or traditional process. We realize that this is a huge claim. However, film has a shorter dynamic range than the human eye. Photographic paper has a shorter dynamic range than film. The results of both can be plotted as an "S" curve in which the highlight and shadows are subject to compression. Piezography K7/K6 inks when used with Piezography K7/K6 curve profiles renders a linearization from dMax to dMin without prejudice to the highlights and shadows. It has many more stops available to the traditional film-based photographer than does darkroom printing paper. For the digital photographer, Piezography can render a dynamic range close to that of human perception. Several digital cameras have been developed that can provide clean digital information which matches the advanced properties of Piezography. However, even ordinary digital cameras can be used to produce prints of unusually long tone. In place of digital cameras, film scanners can be used to digitize traditional negatives and transparencies to produce Piezographs™ which overcome the limitations of wet process papers.

How does it compare to Epson's K3 Advanced Black and White (ABW) system? e like to think that ABW stands for "almost black & white". The ability to render differences in tone between 256 shades of gray is still made superior by dividing the 256 shades into a greater number of shades of ink. Piezography has a much more significant quality edge in both perceived resolution as well as greatly increased shadow and highlight detail. Only Piezography uses three times as many inks as Epson to divide detail in the shadows and highlights, and three times as many inks to divide the detail in the mid-tones. While Epson ABW is "good enough" for many casual photographers, those who take photographs that truly deserve the best printmaking, truly deserve Piezography. But because Piezography is so easy to use, even the casual photographer can print at a higher standard than by using Epson K3 ABW.
