Last week newsletter said:
"Piezography customers have switched from K7 and K6 inks to Piezography Pro inks. As a result, the demand for our original K7 and K6 inks has dwindled to the point that we will discontinue formulating them sometimein 2023."
There will be only Pro(K4) ink no K6/K7 in the future.
But there is a good news. Former "Piezography Monochrome" neutral carbon ink project is still alive.
"Our back burner project is writing a Piezography printer driver for the chipless Epson ET-8550 six ink 13" wide eco-tank printer and developing a pure carbon (our new neutral carbon) ink set"
And it's a K6 ink set!
"We have already developed in-house the new 6 ink pure carbon Piezography ink set based off our nano-carbon which makes up our UltraHD Matte Black ink."
Maybe that is the solution for who loves K6/K7 print quality after Jon Cone stopped selling current K7 inks.
