Epson StylusPro WT7900 Datasheet

Epson EFIDesigner


In 1993, Epson entered the inkjet printing market with the innovative Epson Stylus 800, and introduced its market changing printhead with Epson Micro Piezo technology, making a permanent technological advancement which remains at the forefront today. In 1994, Epson introduced the Stylus Pro, the world’s first 720 dpi colour inkjet printer. In 1998, the Epson Stylus Pro 800 was selected by NASA for the STS-95 mission and Epson introduced the first colour inkjet printer with built-in USB connectivity. Epson continues to develop breakthroughs in technology and applications as print, projection and display needs evolve, building on more than 60 years of innovation of Seiko Epson, which began as a watchmaker.

Epson Stylus Pro 7900/9900 printers incorporate a number of Epson proprietary technologies including Micro Piezo, PrecisionCore, Variable Sized Droplet Technology (VSDT), Exotic Thin Film Piezo (TFP), Low Vibration Meniscus Control, UltraChrome Inks and Look-Up Table (LUT).

Epson introduced the award-winning proprietary piezo-electric technology, called Micro Piezo in 1993, and Micro Piezo has made Epson inkjet printers renowned for their high quality output, reliability, and low running costs. Today, Epson is the only company that uses the piezo-electric printhead throughout its inkjet printing device range, from the smallest personal photo printer to the largest industrial system. Epson Micro Piezo technology fires ink droplets onto a surface by applying an electric charge to piezo-electric elements, which bend when an electrical charge is passed through them. Using piezo-electric technology, the amount of ink pulled into and expelled out of the nozzles can be very accurately controlled by varying the electrical charge given to the piezo-electric elements. This enables the printhead to eject ink droplets in a range of precisely controlled sizes. Ink droplets are propelled instead of heating the ink, which results in a wider range of printing applications and media compatibility, including paper, and industrial applications, fabric printing, indoor filter fabrication and applying patterns to electronic circuit boards. Epson Micro Piezo technology minimises impact on the environment because it uses ink very efficiently and places ink droplets accurately, to prevent wasted paper. The printheads last the lifetime of the printer.

Epson PrecisionCore printhead technology delivers Epson’s renowned industry-leading output quality at high speed. Inch for inch, the high-resolution Epson print chips are one of the fastest inkjet printing technologies in the world. PrecisionCore piezo elements each fire nearly 50,000 times per second. PrecisionCore has up to triple the nozzle density of conventional Epson piezo printheads. The nozzles are roughly 20 microns in diameter and deliver small, round, repeatable dots about 40 microns across. This dot precision creates sharp text and fine lines. PrecisionCore uses the power of the piezo crystal to increase reliability. The piezo element generates a voltage that can detect in milliseconds, whether its firing normally and self diagnose its health. The automatic nozzle check system uses advanced ink droplet detection to eliminate misprinting caused by nozzle clogging. Ink drops with an electrical charge are read by a sensor which takes less than 15 seconds, requires no media and consumes only a miniscule amount of ink. PrecisionCore’s micro-mechanical firing elements avoid material limitations faced by heat-based systems. More colourful and durable ink formulations with higher concentrations of colorants and binders can be used compared to heat-based systems, allowing for printing on a much wider range of substrates. PrecisionCore Scalable Technology is designed for products ranging from industrial systems such as large-scale label presses to desktop printers. Its modularity allows PrecisionCore print chips to be arrayed in both moving serial and fixed line printhead configurations.

Epson Variable Sized Droplet Technology (VSDT) refers to the capability of Epson’s Micro Piezo printhead technology to eject ink droplets of different sizes by varying the electrical charge give to the piezo-electric elements. Epson’s printers can achieve up to five variable sized ink droplets as small as 1.5 picoliters. Such superior precision results in sharp, rich, and virtually grain-free text and images, key qualities strongly associated through the years with Epson’s renowned photo-quality prints. The low temperature of operation makes Epson Micro Piezo printheads compatible with a wide range of inks, including dye and pigment types, solvent inks, and ultraviolet cure inks. Epson Micro Piezo printheads run much cooler than thermal inkjet ones and can provide reliable operation for the life span of the printer. Epson ink cartridges do not require a printhead attached, making the ink cartridges more affordable, and environmentally friendly. Epson Micro Piezo printheads use less power than thermal inkjet printheads because the piezo-electric method of ink ejection is far more efficient.

The Epson Exotic Thin Film Piezo (TFP) printhead and Low Vibration Meniscus Control technologies are the latest advancements in the Stylus Pro 7890, 7900, 9890 and 9900 printers and deliver a superior level of ink placement accuracy and extraordinary photographic quality. The Epson TFP is the highest resolution 1-inch wide high performance inkjet printhead with 360 nozzles per channel. It is capable of using up to 10 separate ink channels simultaneously. Epson Low Vibration Meniscus Control technology delivers highly accurate dot shape and high precision impact point control for extreme dot placement accuracy by precisely controlling the curvature of every ink droplet within each nozzle before releasing it onto the media. There is an ink repelling coating which dramatically reduces nozzle clogging. Variable size droplets, as small as 3.5 picoliters, decreases the print times and optimises the photographic quality.

The award-winning Epson UltraChrome Ink developed for the latest generation of inkjet professional printers is a significant advancement in print technology. Epson has developed several variations of UltraChrome Ink, for different needs and applications. Epson UltraChrome Ink sets are pigment inks with high pigment density and resin coating for more stability and even surface and gloss, and high stability on a wide variety of media including fine art, speciality and plain paper. Epson UltraChrome Inks have superb short term stability and reduced metamerism; ensuring grey tones are consistent regardless of the viewing light source. Epson UltraChrome Inks can be used on a wide variety of media while maintaining outstanding light fastness and made for professional display and sales applications. Epson UltraChrome Inks deliver two times the density of conventional pigment inks, a larger colour gamut, deeper blacks, and superb water resistance. Epson UltraChrome inks are available in High Dynamic Range (HDR), Hi-Gloss, Hi-Gloss 2, K3, K3 with Vivid Magenta and GS. Epson UltraChrome HDR is the ultimate professional photography and graphics arts ink.

Epson UltraChrome HDR features three-level black ink technology. The three tones of black deliver dramatic photographic prints in black-and-white and colour with the widest colour gamut available. Standard photo or matte black is automatically selected depending on the media to optimise density of ink on different medias, resulting in the highest quality in both black-and-white and colour. Light black and light light black, deliver significantly advanced grey balance, impressive mid-tones and highlights for smoother tonal ranges and a high contrast ratio. The combination of black inks means prints are free from bronzing with a uniform surface appearance across both light and dark areas.

Epson Look-up Table (LUT) Technology optimises colour quality and assures maximum colour fidelity across the spectrum. With the expanded colour gamut of the Epson UltraChrome HDR ink, achieving precise colour accuracy requires a significantly more complex conversion programme. Epson New LUT Technology maximises use of the colour gamut and improving ink utilisation by seamlessly integrating high-fidelity ink primaries. Developed through fundamental research conducted jointly with the Munsell Colour Science Laboratory at the Rochester Institute of Technology, Epson New LUT Technology reduces colour fidelity, reduces graininess in skin tones, improves colour inconstancy, and ensures smooth gradations between colours. To print a given colour on an inkjet printer, colour information (either CMYK or RGB) must be converted so that the printer knows which ink colours to blend, and in what amount. To perform the extremely complex calculations required for image data to ink conversion, a massive reference table of colour data called a LUT is used. Image quality is to a large extent determined by the choice of which ink colours to blend, and how much of each should be used. Epson New LUT Technology automatically selects the optimum combination to accurately express the desired colour with the 10-colour Stylus Pro 7900/9900 printer.
