With both Photo and Matte Black ink cartridges installed simultaneously, the Epson Stylus Pro 900 series printers automatically utilize the optimal black ink mode, delivering maximum black density for the chosen media. Taking advantage of the Epson MicroPiezo TFP auto-sharing black ink channel ensures a fast and efficient switch. And to further reduce switching errors, the user can choose to confirm the switching process from the front control panel.

The standard Photo Black ink mode can be used for any media type with professional results. However, for certain Epson media types such as Velvet Fine Art, Enhanced Matte, and UltraSmooth Fine Art, using the optional Matte Black ink mode instead, will dramatically increase your black optical density for even better print quality.
