Epson T642100 UltraChrome HDR Photo Black Printer Ink

When it comes to professional-grade printing, the Epson Stylus Pro 7900 (24-inch) and Stylus Pro 9900 (44-inch) stand out as Epson's premier ten-color printers, powered by the innovative Epson UltraChrome HDR (High Dynamic Range) ink technology. This advanced ink set, featuring a unique blend of orange and green, significantly broadens the color spectrum, enhancing digital printing capabilities for both package and remote proofing market segments.Epson's UltraChrome HDR ink is a high-density resin-coated pigment ink formulation that includes a three-level black ink technology - photo black, light black, and light light black. In addition, it incorporates cyan, light cyan, vivid magenta, vivid light magenta, yellow, orange, and green. An on-board matte black is also included, which can be automatically switched with photo black.This latest iteration of UltraChrome HDR ink delivers a multitude of benefits. Expect reduced graininess in skin tone areas, smoother tonal gradation from shadows to highlights, and excellent short-term color stability. It also offers outstanding long-term lightfastness, highly accurate color control with neutral black and white, and high gloss levels on water-resistant prints.Economical benefits are also a key feature of this product. The introduction of two high-capacity ink cartridges (350 and 700ml) contributes to a lower cost per milliliter of ink. These high-capacity cartridges also reduce the frequency of cartridge replacements, promoting greater unattended printing.The Stylus Pro 7900 and Stylus Pro 9900 are equipped with Epson's MicroPiezo TFP (Thin Film Piezo) print head, featuring 360 nozzles per inch for each of the ten active ink cartridges. This, combined with Epson's Ink Repelling Coating for the print head and Automatic Ink Detection (AID) system, helps to minimize downtime by preemptively detecting and addressing nozzle clogging, thereby eliminating paper waste during the cleaning process.Epson's AID technology employs a sensor near the print head that monitors the electrical charges on the ink droplets as they are fired. A lower than expected electrical charge indicates insufficient ink was fired, triggering the print head cleaning process automatically.Compared to current 8-color 24-inch and 44-inch printers, the print speed of the Stylus Pro 7900 and Stylus Pro 9900 is significantly increased. For instance, the Stylus Pro 7900 can complete an A1 (720x720dpi) sellable quality print on Epson's Premium Glossy Photo Paper in an impressive 5 minutes. This makes these printers an ideal choice for those seeking efficiency and quality in their printing tasks.
