The Epson Stylus Pro 7900 (24 inch) and Stylus Pro 9900 (44 inch) are Epson's first ten colour printers equipped with a revolutionary new pigment ink technology - Epson UltraChrome HDR (High Dynamic Range) ink. This ink set incorporates orange and green to considerably expand the colour gamut and increase digital printing opportunities within the package and remote proofing market segments.
Epson's UltraChrome HDR ink is a high density resin coated pigment ink formulation with three level black ink technology photo black, light black and light light black - plus cyan, light cyan, vivid magenta, vivid light magenta, yellow, orange, and green. Matte black is also included on-board and can be auto-switched with photo black.
This generation of UltraChrome HDR ink delivers reduced graininess in skin tone areas, smoother tonal gradation from shadows to highlights, excellent short term colour stability and outstanding long term lightfastness, highly accurate colour control with neutral black and white, and high gloss levels on water resistant prints.
Reduced costs are realised through the introduction of two high capacity ink cartridges (350 and 700ml) which contribute to a lower cost per millilitre of ink. These new high capacity ink cartridges also reduce the need to frequently replace cartridges which promotes greater unattended printing.
The Stylus Pro 7900 and Stylus Pro 9900 have Epson's MicroPiezo TFP (Thin Film Piezo) print head with 360 nozzles per inch for each of the ten active ink cartridges. Epson's Ink Repelling Coating for the print head and Automatic Ink Detection (AID) system combine to eliminate down time by minimising and detecting nozzle clogging beforehand, and to eliminate paper waste used during the cleaning process.
Epson's AID technology uses a sensor near the print head that counts the electrical charges on the ink droplets as they are fired. A lower than expected electrical charge means insufficient ink was fired, so the print head cleaning process starts automatically.
In comparison with current 8 colour 24 inch and 44 inch printers, print speed is dramatically increased, with the Stylus Pro 7900 completing an A1 (720x720dpi) sellable quality print on Epson's Premium Glossy Photo Paper in an amazing 5 minutes.
