These are the new P-400 cartridge labels for SureColor products we are not even yet discussing let alone hinting at.
Alas, Piezography is not yet officially available on the SureColor P-400. If you want to try it out, you are welcome to. Simply use the existing R2000 curves from the Community Edition. They will work very well with Matte paper but you may see micro-lines with some images and may very well see micro-lines wth some images on Gloss paper. That is why we have not released Piezography for P400, P600, and EU/China P808.
We are in the process of building a new printer driver that will really take advantage of the new SureColors. Our driver enables 5760x2880dpi resolution (Epson only offers 5760x1440 and QTR only does 2880x1440), has better dot control, better dither, full bleed printing, and much more. These new P400 carts are coming out first just because people may want to print (unofficially) on matte paper with Piezography ink and Quadtone RIP. Otherwise, we would keep them to ourselves while we develop the new products for the P-400. We actually have our new driver running on our R&D lab printers. Lots of exciting things to come!
