EPSON Yellow ink cartridge - 700ml for 7900 / 9900

Epson UltraChrome HDR™ Ink
In building on the advances introduced with the the Epson UltraChrome K3 ink with vivid magenta, Epson has engineered the UltraChrome HDR (High Dynamic Range) pigment ink technology. While still retaining its key features, such as three-level black ink for superb grey balance, and smooth tonal gradations from shadow to highlight, UltraChrome HDR comprises several new important innovations that contribute to dramatically enhanced print and colour quality.
One of the most significant advantages of the UltraChrome HDR ink is the inclusion of Orange and Green inks, which bring about dramatic expansion in the colour gamut, especially in the bright /vivid green to yellow, and yellow to red ranges. In particular , with the new orange ink, the Epson HDR ink techniology delivers a major recuction in image grain that is typically evidenced ink skin tone reproductions.

• Unique High Dynamic Range (HDR) pigments for an extremely wide color gamut
• Ten-color printing system including all-new orange and green inks
• Designed to work with Epson AccuPhoto HDR screening technology
• Professional print permanence ratings
• Outstanding short-term color stability for mission critical proofing applications
• Improved Microcrystal Encapsulation™ Technology for reduced gloss differential
• Improved black density up to 2.6 with an L value ~3.0

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.
