Printing technology HP presented new products at the Predrupa press conference. From the perspective of the graphic arts industry, the Indigo 7000 is probably the most interesting innovation.
Back at Drupa 2004, Hewlett-Packard (HP) set out to become one of the world's largest suppliers of printing systems for the graphic arts world within just a few years. This had to be taken seriously, as HP had previously acquired and integrated the high-end digital printing pioneer Indigo. Today, four years later, HP has come much closer to achieving its goal: Through organic growth, an emphasis on innovation and targeted company acquisitions, the company has strengthened its own position. Due to the figures available, it is difficult for an outsider to break down the individual areas in detail. However, the figures announced by HP are impressive: around 5,000 HP Indigo systems are in use worldwide, producing more and more pages. According to HP, the number of pages printed on Indigos rose by 45 percent in 2007 alone. HP can also boast high growth rates in large-format inkjet, with last year's growth amounting to 25 percent. HP now sees itself as the market leader in various market segments:- High-end digital printing systems
- Large format inkjet systems
- Direct mail addressing
- Digital label printing
- Large format plotter for technical applications
- OEM inkjet printheads
This is all the result of a strategy called "HP Print 2.0". The key elements of the strategy are: the development of the latest generation of digital printing platforms, the simplification of printing via the web and the increasing distribution of digital content.
The classicSince the introduction of high-end digital printing systems, experts and, of course, printers who want to know which technologies they should invest in, have been asking the following questions: Will digital printing replace classic offset printing, and if so, when? Stephen Nigro, Senior Vice President of HP's IPG Graphics and Imaging Business Division, had clear answers at the Predrupa press conference: "Yes, we at HP are convinced that digital printing will replace offset printing. There is no reason to assume that things will develop differently in the printing sector than in photography, for example. However, nobody knows today when this will happen - in ten, fifteen or twenty years?" And that is precisely the problem for the many offset printers. The fact that they are not investing in digital printing on a large scale has nothing to do with obtuseness, but with business realities. And offset printing is still the cheapest printing process. Anyone whose business is to produce print products at the best possible price cannot wait years for the prediction of digital printing to come true. Various manufacturers of digital printing systems have recognized this and are working on systems that will not only open up new markets such as personalization or web-to-print, but will also at least keep pace with A3 offset presses in terms of print quality and productivity. It is precisely this mass business that is also attractive for manufacturers. HP backed this up with figures: in 2007, according to one estimate, 2 percent of all A4 pages produced in the industrial sector were produced on digital printing systems, with the remainder being produced using traditional printing processes. However, the value of printed matter produced using digital printing amounted to 16 percent of the pie. This can only mean one thing for a manufacturer like HP: Why do one thing (personalization, individualization, specialties, web-to-print) and leave the other (production of conventional print products)?
The HP Indigo 7000HP Indigo has been pursuing precisely this philosophy for several years now. If a print shop opts for a digital printing system today, it must also be able to produce not only personalized or individualized print products, but also so-called "08/15 jobs". With the HP Indigo 3500 and the HP Indigo 5500, which was launched on the market just last year, HP has brought systems onto the market that already largely meet these requirements. With the HP Indigo 7000, HP intends to significantly increase the performance of the Indigo series once again. At the press conference, the company spoke of a doubling of pure printing speed compared to the predecessor model, while overall productivity is expected to increase by a third. Interesting: nobody is talking about quality anymore. This is always a sign that a technology is perceived to be suitable enough. In terms of printing technology, the HP Indigo 7000 is based on its predecessor, the HP Indigo 5500, but the so-called print engine has undergone numerous minor and major improvements to achieve a significantly faster printing speed. The specifications of the HP Indigo 7000 at a glance:
- 7200 A4 4/0 per hour
- Image sizes of 317 x 464 mm possible
- Improved serviceability and increased uptime with diagnostics and troubleshooting functions in the machine
- Fast exchange of printing inks to enable changes to the 5th, 6th and 7th color while still in the machine and almost without interruption
- Media format: 330.2 x 482.6 mm
- Grammages from 60 to 350 g/m2 printable
Together with the presentation of the HP Indigo 7000, which is intended for commercial printers (the machine is to be available as early as this year), a new web press, the W7200, is to be launched on the market at a later date (mid-2009). Interesting: In contrast to the currently marketed w3250, where the two printing units are directly coupled to each other, the paper web transfer on the W7000 takes place via a so-called buffer construction.
HP SmartStreamUntil now, HP has lacked a cross-platform digital workflow for the various print systems. This is now set to change with the introduction of HP SmartStream workflows. HP SmartStream is a portfolio with various workflow components that allow customers to support the development of solutions for digital print production. According to the manufacturer, HP SmartStream Workflow was designed as an open environment. This allows the integration of third-party applications. The most important advantages of the solution are
- Large file processing, variable data management, imposition and image management for commercial printers as well as for direct marketing, photo book printing, the label segment and packaging
- Shared data usage and feedback between the workflow components from the preparation of print jobs to their processing.
- A central element of HP SmartStream is HP's partnership with various partners - HP calls these "HP Smart-Stream Partners". In terms of prepress workflows, Agfa Apogee X, PODS Creo-Prinergy, Heidelberg Prinect and Screen Trueflow are currently supported. As already mentioned, HP SmartStream is to become the digital workflow for the entire HP product range (HP Indigo, HP Inkjet Webpress, HP Designjet and Scitex). The only exceptions are the controls for the plotter systems in the technical area and the niche market printing systems (special direct mailing applications and CD/DVD printing systems).
Latex and high-speedIn addition to products that are already close to production readiness, HP also presented new technologies and systems that can only be seen in full configuration at Drupa 2008. Nevertheless, these are exciting technologies that could shake up the respective markets. Fascination number 1 is the HP Latex printing technology. This ink was developed for large-format inkjet printing. Both indoors and outdoors. The highlight: the latex ink is water-based, but thanks to the specially developed latex technology, it is said to have many of the advantages of solvent-based inks. According to HP, printouts produced with latex ink only release volatile organic compounds in very small quantities. This eliminates the need for the ventilation required when using solvent-based inks. Nevertheless, latex inks are said to achieve the best results even on difficult substrates. HP promises its customers that such prints, unlaminated, will have an outdoor durability of around three years. During the Predrupa demonstration, the trade press in attendance were not yet able to inspect an operational printing system with latex ink. However, print samples were handed out to demonstrate the results of the technology. In addition to the latex technology, another announcement captivated the trade press representatives: It is the new HP Inkjet High-Speed Web Press. According to HP, the continuous feed machine will set new standards with a web width of up to 762 mm. In CMYK mode, the machine is said to have a printing speed of 122 meters per second (that's around 2600 4/0-A4s per minute). The machine is designed for applications with around 70 million impressions per month. Thanks to the "Bonding Agent" technology, the system should not be dependent on special print media. HP is not yet able to say exactly when this system will be available on the market, but is currently expecting it to be available in the second half of 2009. Just how serious HP is about this system can be seen from the fact that it is already giving details of the price at an early stage: the new machine is not expected to cost more than 2.5 million US dollars.
