How does an HP Indigo press work?
HP Indigo uses a blanket to transfer ink to media. The blanket is heated, melting and blending the ElectroInk particles into a smooth film. This produces an image that is completely defined on the blanket, transferred to the substrate by direct contact.
When did HP buy Indigo?
2000
HP Acquisition In 2000, Hewlett-Packard made a $100m investment in Indigo, buying 14.8 million of Indigo’s common shares, which represented 13.4 percent of the company’s outstanding shares.
What is Indigo machine?
HP Indigo Digital Press ElectroInk and the HP Indigo process deliver crisp linework, attractive images and smooth vignettes with a very thin ink layer that gives uniform gloss between ink and substrate.
How many colors can the Indigo digital Press print?
two-color
Printing speed: 240 two-color or monochrome 8.5 x 11 (A4) PPM.
What is liquid electrophotography?
Liquid electrophotography (LEP) is a “thermal offset” process created by Indigo to use a liquid toner. An electrostatically charged Photo Imaging Plate (PIP) mounted on the imaging cylinder is scanned by laser diodes controlled by the RIP (raster image processing) software.
What is HP Electroink?
Electroink is a liquid ink used exclusively with Rex 3’s HP Indigo 7900, the latest in digital printing technology. Unlike traditional commercial digital printing dry-toner, HP’s Electroink is a liquid ink that combines the advantages of traditional electronic printing with the unique properties of liquid ink.
How does digital printing work?
Digital printing differs from traditional, analog printing methods–such as offset printing–because digital printing machines do not require printing plates. Instead of using metal plates to transfer an image, digital printing presses print the image directly onto the media substrate.
What are the 3 types of electrophotography?
Others include ion deposition (ionography), electrostatic, magnetographic (magnetography), and electrographic (electrography). Electrophotography involves the removal of negative charges by the use of light from the surface of a photosensitive cylinder, which is then covered with the toner.
