OKI experts to sermon: What a LED printer! -OKI, LED, printing – silk screen printing industry, especially web
In the printer industry, OKI can be described as the only all-LED technology to create a page printer manufacturers (page description page printer that printer, laser printers also package), so it is in the LED printing technology has the strongest voice. However, the penetration rate of LED printer is not as good as laser printers, many people still know little about LED print technology, in order to dispel doubts, the media director of the Institute before OKI images, LED technology experts Yamamoto) Tang Chun-site mirage? Jealous Feedback?
Site according to Gadfly Yamamoto) Mu Qiang broom? Following the implementation strategy? 006 years ago, LED printer using the digital LED print head, print quality equivalent to laser printers, based on dual-class printing, print resolution from 300dpi, 600dpi up to 1200dpi, print speed of 30ppm from the elevated to more than 8ppm; after 2006, with EFBLED print head (EFB, Epi-FilmBonding), print quality may surpass laser printers, multi-level printing, print resolution of true 1200dpi, print speed gradually forward to 60ppm.
EFBLED the birth of the print head is a key node, it makes LED print head manufacturing cost in the print resolution and has broken through. LED light is a compound semiconductor film is very thin, the material used is GaAs, arsenic are highly toxic, generate light membrane substrate must first be generated after completion of light-emitting film stripped from the substrate, and then stripped of the light membrane close to the IC silicon paste, and then the luminous film strip cut by erosion processes one by one of the LED light, and finally to metal wiring. In the print head using EFB technology manufacturing process, the light membrane and IC chip bonding is the most difficult, OKI has adopted a new technology that uses molecular bonding to the two closely. Stripping process is very complex, of which only 2 microns thin base plate can be reused, with the increased output, which also help reduce production costs.
LED printers than laser printers, the movement is less rotating machines, there is no complicated components of optical lenses, the structure is more streamlined, compact, conducive to miniaturization, higher reliability, LED print head also has in 2000 The first generation of 205cm3, 170g narrow for the current fourth-generation (EFBLED) of 33g, 50g. LED printer technology easier resolution and color depth in the balance between its multi-level image enhancement technology, each LED light source can change the length of time connected to the formation of multi-level dot matrix LED brightness levels of different halftone unit, currently produces 64 gray levels; and laser printing is still a dual-level control to 100% and 0% brightness to provide dot matrix, dot matrix polymer to generate a semi-tone unit, which must be between resolution and color depth choose each other. In EFB technology, further reducing the metal wiring, print resolution upgrade will not make the print head costs, and laser printing to enhance the resolution of the print component will bring significant cost pressures. With the increase of printing speed, laser print resolution will be reduced, while the LED print resolution is not affected. In addition, LED print point diameter has been reduced to 25 microns, the resolution can be more easily up to 2400dpi, the future of Blu-ray is also up to 4800dpi, and the point of laser printing has the smallest diameter of 55 microns, such as not using Blu-ray resolution more difficult to further improve, or will the optical components, electrical and other design and costs of the unrelenting challenge.
