HP DesignJet T790 (24 inches) Large Format Printer

MORE INFORMATION

More information on HP DesignJet proprietary technologies

For over thirty years, HP has been transforming the way design professionals in Architecture, Engineering, Construction, Geospatial and Graphics markets operate. In the late 1970’s, HP developed the first pen plotter and HP-GL graphics language, now the industry standard. In the early 1990’s, HP invented inkjet technology and applied it to DesignJet printers, making large format printing in black-and-white easy, fast and affordable. HP continued to innovate, and introduced colour, faster printing speeds, and the ability to print high resolution images and complex files in large format in the same decade. In the new millennium, faster printing speeds and sunlight-resistant UV inks were introduced, allowing Print Service Providers and Graphics Designers to create applications for both indoor and outdoor use. Photographers began to adopt HP large format printing to replace silver halide, demonstrating HP’s ability to deliver superior image quality with prints lasting up to 200 years. In 2010, with the rise of mobility and globalisation, HP launched its first generation of ePrinters with web-connectivity features and the first multifunction large format ePrinters with copying, scanning and printing in a single device. HP have shipped over 3 million DesignJet printers around the world and are the leader in the market with the widest range of large format printers for design professionals, whether single or multi-user environments.

HP DesignJet T Series Printers feature HP thermal inkjet technology and use a number of advanced HP proprietary technologies to achieve incredible accuracy, sharpness and superior colour fidelity. HP DesignJet T790 Printer Series features HP Scalable Printing (SPT), HP 72 printheads and HP Vivera inks, and ColorPRO Technology.

HP Scalable Printing Technology (SPT) allows HP Designjet T Series and Z Series printers to deliver higher quality at higher speeds with more ink colours. HP SPT is the result of HP’s investment of $1.4B and four years of research and development. SPT printheads were first introduced in 2005, and incorporate fluidic design and electronic control features required to meet the demands of commercial and industrial inkjet printing. HP thermal inkjet printheads are produced on a silicon wafer using SPT integrated circuit manufacturing processes customized for HP inkjet applications. SPT offers higher density circuitry that can place more electronic functionality on the printhead than was possible in previous generations of HP thermal inkjet printheads. Each SPT-based printhead incorporates electronic circuits that process input and output signals, manage power, control the drop generators and measure the printhead temperature. Ink channels, drop generator chambers and nozzles for the printheads are built tighter across the surface of the silicon wafer and the manufacturing techniques for SPT produce complete, integrated printhead structures with features that are defined and aligned together with sub-micron precision.

The HP DesignJet T790 Printer Series uses new HP 72 printheads which feature automatic self-maintenance and nozzle substitution routines to provide flawless image quality, lower running costs andmore efficient ink usage during installation and cleaning routines. The three HP 72 printheads are part of a module that integrates the HP Thermal Inkjet printheads with ink delivery systems for the six inks. HP 72 ink cartridges are mounted on the printhead carriage and scan with it across the paper. HP 72 printheads features 1056 nozzles. The ink drop size ranges from 6 picoliters (cyan, grey, magenta and photo black) to 9 picoliters (matte black, yellow). To ensure dependable and consistent image quality every time, the drop-ejection performance of every nozzle is periodically and automatically tested with an Optical Drop Detector.

The HP DesignJet T790 Printer Series features HP Vivera inks with the HP 6-ink writing system, designed and engineered together to provide high quality, high reliability, optimised efficiency and a wide colour gamut. HP Vivera colour inks are aqueous dye-based, (cyan, grey, magenta, photo black, and yellow) for the best range of colour across a range of printing materials to produce colours optimised for technical graphics and CAD applications. Precision colour-to-colour alignment in the HP72 printhead and dye-based HP72 Vivera colour inks deliver sharp colour lines and text, a wide colour gamut with smooth colour transitions. The HP Three-Black Ink set: photo black, matte black and light grey is included with the 6-ink writing system. The two black inks, photo (pK) for photo media with glossy and satin finish and matte (mK) for matte media such as fine art paper combined with the light grey ink, significantly reduce image grain and metamerism (greys appear green under fluorescent lighting) and provide accurate reproduction of neutral grey tones from white to black. The HP Three-Black Ink set prints true neutral greys and rich, dark blacks whether using matte or glossy papers, without wasting time and money swapping ink cartridges. HP Vivera pigment-based black ink delivers sharp black lines and text with maximum black optical density. HP 72 inks are fast-drying and smudge-resistant and produce superior lines and text and smooth colour transitions in images, renderings and illustrations. HP 72 ink cartridges are mechanically-keyed and colour-coded to ensure they are inserted into the proper ink slot. Ink cartridges are easily removed by a simple push-to unlock/pull-to-remove motion and installed by pushing them into their slot until the lock.

ColorPRO Technology is a licensing programme for a wider range of media products, technologies and applications. ColorPRO Technology was originally designed for uncoated papers containing proprietary surface-treatment chemistry resulting in bolder blacks, brighter colours and sharper lines when printed with aqueous–pigment based inks, ColorPro now includes coated papers, textiles, and films for large format printing applications. Papers and media with ColorPRO Technology perform to a strict set of specifications to meet industry–leading performance standards The specific technology behind media with ColorPRO Technology varies from product to product, however all products with ColorPRO Technology utilise advanced technologies which have been designed together with Original HP inks and HP printers to optimise printing system performance.

HP DesignJet printers are part of the HP Eco Solutions programme, aimed at energy usage, carbon footprint, recycling and environmental considerations. HP Designjet printers meet strict energy efficiency guidelines without sacrificing performance or your productivity. HP DesignJet printers are ENERGY STAR® compliant to help you keep your energy costs down. ENERGY STAR is a joint program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy. HP also aims to make it easy for you to reduce the carbon footprint of your printing.

HP DesignJet printers are designed for recyclability. HP Planet Partners programme is for recycling your HP DesignJet ink cartridges. All HP print cartridges returned go through a multiphase recycling process where they are reduced to raw materials. These materials can then be used to make new metal and plastic parts and products. No HP print cartridges returned and recycled through HP Planet Partners are sent to landfill. Most HP DesignJet printheads can also be returned through the HP Planet Partners programme. When it’s time to upgrade or dispose of your HP DesignJet printer, HP offers several environmentally sound options for renewing or disposing of your unwanted hardware. HP Trade-in, HP Buy-back, and HP Planet Partners recycling programmes are all viable options. Design Supply will be able to help you decide which option is best for you.
