New Print Head BC-1350 is a newly developed 1-inch print head that enables 4 picoliter droplet printing with pigment-based ink. With a 4pl ink droplet, the graininess of the image is significantly reduced, producing a sharper and more vivid image. The new print head enables the printers to attain 1200 x 1200 dpi standard resolution. The enhanced resolution is 2400 x 1200 dpi that provides much sharper image than the predecessors. Both the W6400 and the W8400 employ a 1.07 wide high-density print head with 1,280 nozzles per color for a total of 7,680 nozzles.
