iphone Photo PiezoDN Output

Dear All

Did anyone has the experience using iPhone 6 plus photo to output PiezoDN negative???

What would be the maximum size that you guys think the negative is acceptable??? And did anyone has some useful method that can help us to output bigger negativeS?? I would appreciate if someone can share your experience.

Many thanks


Early in the development of PiezoDN we printed an iphone photo at 6x6 inches. It was surprisingly good! It could easily go larger.
