HP Indigo 7000
Philip Chadwick, PrintWeek, 27 March 2009
HP’s latest press, the Indigo 7000, takes one step closer to narrowing the technology gap between digital and litho, discovers Philip Chadwick.
While there is still a place for both digital and litho print technologies, the gap between the two is closing. The level of quality offered by digital presses has come on in leaps and bounds over recent years. At Drupa 2008, the digital presses on display were more robust and more industrial – in simple terms, more like litho. That’s certainly the view of HP; it believes that its latest challenger to the commercial market, the HP Indigo 7000, is well placed to take digital to the next level in terms of quality and viability.
“We are close to a tipping point, where digital print is going to truly explode,” explains Robert Stabler, head of HP’s Indigo digital business for the UK and Ireland. “I think there are a lot of reasons to be bullish about the growth of digital. People are starting to think the unthinkable.”
The 7000 is one of HP’s flagship digital presses and is the next step up from the 5500 machine. While it doesn’t venture into any uncharted waters, it can serve a wide range of different applications from direct mail and photobooks, through to greetings cards and calendars. It sits nicely in the general commercial print market, which is why HP selected Precision Print to put the 7000 through its paces before it went to market. The Barking-based company is a long-standing HP customer and already had a 5000 in place.
Environmental benefits
“On the 7000 we found that the run length can be broadened and we are able to move more work from litho,” explains Gary Peeling, Precision Print managing director. “It means that we can make great strides in waste reduction – we use less material and that helps underpin our clients’ environmental programmes.”
The manufacturer is keen to flag up the environmental benefits of the 7000. HP says that the press offers an oil recycling system, lower electricity consumption, the ability to print on recycled paper and that its consumables last longer, resulting in reduced waste. Then there is what the digital market believes to be the environmental trump card: the ability to print the precise quantity required.
“People go for shorter run lengths because of the economics, adds Peeling. Digital printing allows them to have what they need, when they need it. It also allows us to use a different solution when dealing with the environment.”
Colour considerations
With the reduction of waste at the heart of this machine, even the design of the ink cans has been taken into consideration. The cans for the 7000 are much bigger than those for the 5500, which means that they don’t have to be changed as often, and can also be replaced on the fly.
With colour in the corporate world so important, according to HP, the inks for the 7000 provide a far wider colour gamut with four-, six- or seven-colour Pantone emulation, including Pantone Goe and off-press mixing of spot colours, which can be achieved with HP Indigo’s Ink Mixing System. As a result, the 7000 can match up to 97% of Pantone colours.
Other areas in which Precision says the 7000 scores highly include the speed of the machine and the workflow. The 7000 has been upped to a speed of 120ppm in four-colour mode and 240ppm in mono or two-colour mode.
On the front-end, HP has developed a scalable SmartStream print server offering a remote user interface, better variable-data printing attributes and an expandable RIP capacity. “It means you can control multiple presses from one digital front end,” adds HP’s Stabler.
By separating the RIP from the press, HP has developed a scalable workflow that can handle huge volumes of variable data. Customers can choose from three print servers from the SmartStream family to drive the press via the PrintLink protocol, which separates the pre-press tasks from the printing. According to HP, this allows press operators to concentrate on printing operations, thus maximising pressroom productivity. The three SmartStream products best suited for the 7000 are Production Pro, Production Plus powered by Creo, and Ultra. Also incorporated into the 7000 is the HP Indigo Print Care toolset, which offers on-press and off-press diagnostics and troubleshooting tools.
The 7000 can handle media weight of 80-350gsm for coated paper, while for uncoated it can handle 60-350gsm. Media thickness ranges from 70-400 microns. There are three 1,800 sheet capacity trays and there is an option for an extra 700 sheet tray. Media size is pitched at 330.2x482mm, while image size is at 317x464mm.
The ‘wow’ factor
It all adds up to a heavier-duty machine compared with the 5500. While the company isn’t making any claims that it’s the beginning of the end of litho, there is a feeling within HP that with the 7000, it can certainly bridge the gap a little better.
“The B1 market is still best suited to longer runs but there is now a middle ground where you can go one way or the other – the market has polarised,” says Stabler. “Run lengths are coming down and it is more efficient to opt for digital than a small litho press. This press goes up to SRA3 paper size and prints to a litho quality – ideal for customers working on high-quality applications.”
In addition, the 7000 is expected to exploit markets that are well suited to digital. Highly personalised direct mail has long been the mainstay of the digital market, but there are others sectors in which the technology seems to be finding favour, with the aforementioned photobooks, personalised calendars and greetings cards all benefiting from the combination of advanced variable-data and web-to-print systems.
“Applications like that still have a ‘wow’ factor,” adds Stabler. “It has grown over the last three years. People are now more aware that they can create their own photobooks or cards – my expectation is that the market will grow at an accelerated rate.”
On top of that, the 7000 may find additional applications in the on-demand books and magazine markets. The latter, in particular, might be considered uncharted territory for digital, but Stabler believes that there is a market with magazines of run lengths of 7,000 or less.
“If you look at specific applications, it makes sense to go digital,” adds Stabler. “The technology is very reliable, the economics have improved and the quality is very good. Also, this is a segment that is not commoditised.”
It’s a clear sign that digital print technology is approaching maturity with litho manufacturers scrutinising the latest developments with interest.
The 7000 is not the only heavy duty, industrial digital press in HP’s arsenal. However, it does give the manufacturer more confidence when going up against not only the giants of the digital sector but the previously untouchable litho market. That tipping point could be just around the corner.
