HP Pre Drupa Briefing - HP to introduce Latex ink technology

In a major announcement made today, along with many other major announcements at their pre-Drupa event held in Tel Aviv, Israel, HP unveiled their new Latex Ink Technology which will be demonstrated at Drupa 08 and should be commercially available at the end of the year on new Thermal Inkjet Printers which will also be announced at Drupa in May.

The new technology cannot be retrofitted to older machines, nor can older machines utilise the new ink.

We were assured that the Latex inks will sell for a similar price as the existing solvent inks.

Here’s what HP said about their new product……

Designed with the environment in mind, HP Latex Printing Technologies offer users a compelling new printing alternative for a wide variety of outdoor and indoor applications. Together, HP Latex Inks and HP Thermal Inkjet Technology provide durable (they claimed up to 3 years outdoor without lamination), odourless prints(1); sharp, vivid image quality; application versatility; and high productivity – all of which enable users to increase their print capacity and grow their businesses while reducing the total impact of printing on the environment.

Broad outdoor and indoor application versatility
HP Latex Inks deliver long-lasting, durable prints that withstand the elements while also providing sharp, vivid image quality that stands up to close inspection. The inks produce great results across a wide range of media – including most low-cost, uncoated solvent-compatible media – and eye-catching, consistent results with Original HP large-format media designed together with HP Latex Inks.

HP Latex Printing Technologies can produce a broad range of outdoor and indoor applications, from point-of-purchase displays, transit signage, wall murals and exhibition graphics to billboards, vehicle wraps and exterior event signage. This outdoor and indoor application versatility gives users more possibilities to meet customer needs. Outdoor prints produced with HP Latex Inks achieve display permanence up to three years unlaminated and are scratch, smudge and water resistant on a range of media.(2)

Print with the environment in mind
Water-based HP Latex Inks provide many of the benefits of solvent-ink technology without imposing the typical environmental, health and safety considerations. Odourless prints(1) produced with HP Latex Inks emit extremely low levels of VOCs (volatile organic compounds). There is no special ventilation required to meet occupational exposure limits and there are no requirements for air discharge permitting,(3) facilitating an improved printing environment. In compliance with a number of industry-leading certifications, including Nordic Swan, HP Latex Inks do not produce ozone emissions during printing and contain no HAPs (hazardous air pollutants).(4)

High-speed, quality printing – reach new levels of productivity
HP Wide Scan Printing Technology makes it possible to develop new printing systems that can achieve breakthrough print speeds(5) – outdoor quality prints at approximately 70 square metres/hour and indoor-quality prints at approximately 35 square metres/hour.(6) And there’s no manual daily maintenance required.(7)

HP Wide Scan Printing Technology is scalable, high-speed technology. The combination of multiple 4.25-inch (108 mm) printheads and precision media advance control using the HP Optical Media Advance Sensor delivers new levels of productivity.

The sensor is a proprietary technology that provides precise and accurate motion control of media advance between print swaths. Improved accuracy minimises or eliminates banding for high-speed, quality printing.

Key features and benefits: 

  • Outdoor prints produced with HP Latex Inks achieve display permanence up to 3 years unlaminated and up to 5 years laminated and are scratch, smudge and water resistant on a range of media – performance comparable to solvent-ink technology.(2)
  • Indoor prints produced with HP Latex Inks achieve display permanence – in-window up to 5 years unlaminated and up to 10 years laminated on a range of media.(8)
  • HP Latex Inks together with HP Wide Scan Printheads produce a wide colour gamut – comparable to solvent-ink technology – for sharp, vivid image quality whilst making it possible to produce high-quality output at fast print speeds, supporting an ink drop size as small as 12 picoliters.
  • HP Latex Inks produce odourless prints,(1) providing the best of both worlds. Prints are durable enough for demanding applications such as outdoor display but they lack the noticeable odour that can limit indoor applications – a characteristic more typical of prints produced with solvent-ink technology.
  • A proprietary new HP media surface-treatment technology – designed together with HP Latex Inks – produces a wide colour gamut that makes it possible to achieve both durability and sharp, vivid image quality on materials that don’t typically print well with solvent inks, such as woven High Density Polyethylene (HDPE) and Tyvek.
  • HP Latex Inks achieve the optimum in high-quality, consistent performance on HP large-format media – designed together to work better together with HP Latex Inks. The variety of HP media includes both outdoor and indoor applications and ranges from low-cost, uncoated media to a variety of specialty options. HP large-format media also includes a range of recyclable substrates.(9)
  • Non-hazardous HP Latex Inks are not classified as a hazardous material per transportation requirements, there are no hazard warning labels, and they are not considered hazardous waste.(10) These inks are non-flammable and non-combustible.
  • Designed to reduce the impact of printing on the environment – an innovative new ink cartridge design uses a recyclable cardboard container and reduces materials use.
  • HP Wide Scan Printing Technology is scalable, high-speed technology enabled by an arrangement of several HP Wide Scan Printheads together with HP’s proprietary Optical Media Advance Sensor. This combination delivers outdoor-quality prints at approximately 800 square feet/hour, indoor-quality prints at approximately 400 square feet/hour.(6)
  • HP Wide Scan Printheads support a firing frequency of up to 24 KHz. Each HP Wide Scan Printhead contains two colours of ink and 1,200 nozzles per inch or 10,560 nozzles per printhead for the precise, accurate placement of ink on the page at high-productivity print speeds.
  • Unlike printing systems using solvent-based inks, HP printing systems using water-based HP Latex Inks and HP Wide Scan Printheads do not require daily manual maintenance of the printheads.(7) Individual printheads are user replaceable, eliminating the down-time and expense of a service call. HP Latex Inks are formulated to maintain nozzle health to optimize printhead performance, ensuring the reliable operation critical for keeping workflows running smoothly.
  • HP Latex Inks are completely cured inside the printer to form a durable film on the print medium. Prints come out of the printer ready to use, finish and prepare for shipment.
  • HP designs quality and reliability into every innovation. Original HP Latex Inks, HP Wide Scan Printing Technology and Original HP large-format media are designed, engineered and tested together as a system to ensure the reliable operation critical for keeping workflows running smoothly.

(1) Printers using HP Latex Inks use internal heaters to dry and cure the latex polymer film. Some substrates may have inherent odor.
(2) HP image permanence and scratch, smudge and water resistance estimates by HP Image Permanence Lab. Display permanence tested according to SAE J1960 using HP Latex and solvent inks on a range of media, including HP media; in a vertical display orientation in simulated nominal outdoor display conditions for select high and low climates, including exposure to direct sunlight and water; performance may vary as environmental conditions change. Scratch, smudge and water resistance tested using HP Latex and solvent inks on a wide range of HP media. Laminated display permanence using Neschen Solvoprint Performance Clear 80 laminate. Results may vary based on specific media performance.
(3) Special ventilation is not required to meet U.S. OSHA requirements on occupational exposure to VOCs from HP Latex Inks. Ventilation equipment installation is at the discretion of the customer – no specific HP recommendation is intended. Typically no air discharge permitting required with inks that emit extremely low levels of VOCs. Customers should consult state and local requirements and regulations.
