In our never ending quest to update and upgrade workflows, we’ve created a brand-new Digital Negative system we are calling PiezoDN. This new system dramatically streamlines the workflow for digital negatives and also uses standard K7/P2 ink sets. There is no longer a need for the special 2.5 and 4.5 shades. If you are just getting into Piezography Digital Negatives we highly suggest you check out the new system
