HP Indigo Division is a division of HP's Graphic Arts business. It was founded in 1977 as the Israeli company Indigo Digital Press and bought by Hewlett-Packard.The name Indigo comes from a company formed by Benny Landa in 1977. Landa, known as the father of digital offset color printing. It develops, manufactures and markets digital printing solutions, including printing presses, proprietary consumables and workflow. Founded in 1977, it was an independent company until it was acquired by HP in 2001.
Customers of HP Indigo solutions include commercial printers, photo specialty printers, and label and packaging converters to print applications such as marketing collateral, photo albums, direct mail, labels, folding cartons, flexible packaging, books, manuals, and specialty jobs.The ability of digital presses to print without plates enables the use of variable data such as text or images, such as in personalized direct marketing applications, or in photo albums, which are usually printed in copies of one. Digital presses also make short-run and just-in-time printing cost-effective. In this way, digital presses have changed the economic models for print in a wide variety of market segments, cutting down on supply chain costs and simplifying the creation of campaigns that reach consumers in more creative, personalized ways.
There are several families of HP Indigo presses, whivch can be broadly grouped by the type of paper-handling mechanism they work with: Sheetfed (or cut-sheet) or Webfed (or roll-fed).
Sheetfed presses print on sheets, have a feeder system consisting of drawers and/or a pallet of paper, and print on both sides of the paper (duplex print/perfecter), printed sheets are collected in a stacker mainly for paper printing. Examples of sheetfed presses include the HP Indigo 7900, the HP Indigo 10000 and the new HP Indigo 12000.
Webfed presses print on rolls, often referred to as a web the feeder system (unwinder) feeds the paper through continuously in most cases, print on one side of the substrate (simplex) printed rolls can be collected on a rewinder or cut into sheets (sheeter). Examples of Webfed presses are the HP Indigo WS6800 narrow format press for labels and flexible packaging, the Indigo 20000 digital press, and the Indigo W7250 for books, photo and other commercial applications.
The launch of the HP Indigo 10000 digital press in 2012 marked the first time the company embarked on a platform that supports a paper size beyond A3. With the B2/29.5" paper format, they aim to increase the productivity and application range of traditional print service providers.
Each Indigo press has up to 7 color stations, which can use cyan, magenta, yellow, black and a variety of special and spot color inks, such as white, silver, UV red and transparent.
HP provides the option for users to mix their own ink colors to match Pantone references. This is common with non-digital offset litho presses, and is one of the features that distinguishes the HP Indigo process. "Off-press" colors are mixed from 11 color (from the 15 original) Pantone spectrum at an offline, ink mixing station. Users can also order special pre-mixed colors from HP Indigo, for example fluorescent pink. HP Indigo presses are available in configurations supporting four, five, six or seven colors.
