HP Latex Printing Technologies Proven HP Latex Printing Technologies are revolutionizing the way the world prints. Introduced in 2008 as a result of over 10 years of research and development investment, thousands of HP Latex Ink systems are now employed worldwide and have printed more than 35 million square meters.

Introduction

HP Latex Printing Technologies produce high-quality images on a broad range of coated and uncoated media including PVC banner, self-adhesive vinyl, PET films, paper, wallcoverings, and textiles.1 This gives print service operators the versatility to cover applications including retail and outdoor advertising, event and exhibition graphics, vehicle graphics, and interior decoration. The water-based formulation of HP Latex Inks meets high environmental standards that improve the work environment and meet customers’ environmental objectives for indoor displays and wallcoverings.

The HP Latex 3000 Printer features a writing system with more than 70,000 nozzles and advances based on HP 881 Latex Inks, HP Latex Optimizer, and HP 881 Latex Printheads to deliver industrial-scale efficiencies ideal for large print service operations. HP Latex Optimizer delivers consistent image quality and supports high-efficiency curing of HP Latex Inks at lower temperatures and with less energy than previous HP Latex Printing Technologies. Dynamic swath alignment suppresses banding even at the highest levels of productivity.

This technical white paper provides an in-depth look at the new technologies in the HP Latex 3000 Printer.

HP 881 Latex Inks

HP 881 Latex Inks are formulated to optimize and maintain the high performance and print quality of HP 881 Latex Printheads, and they work with HP 881 Latex Optimizer to provide high print quality at high productivity.

HP 881 Latex Inks have a water-based formulation with an innovative “latex” polymer that produces a durable, flexible film protecting the image. Prints are completely dried and cured in the printer and are ready to use. A 6-color system of pigment inks—cyan, magenta, yellow, black, light cyan, and light magenta—produces a wide color gamut.

HP Latex Inks are supplied in recyclable 5-liter containers2 for low intervention rates that support industrial productivity. Ink cartridges can be hot-swapped while the printer is running and are mechanically and electronically keyed to prevent ink mixing by installing the wrong cartridge.

HP Latex Ink cartridges feature built-in electronic intelligence that communicates ink color, remaining ink quantity, and other information to the printer. For example, the printer reads a “use by” date from each cartridge to that indicates the ink is fresh and meets requirements for system reliability and performance. Intelligent supplies support smart inventory management and reduce waste: if a partially-used cartridge is reinstalled, the remaining ink level is read by the printer and displayed to the operator. Intelligent supplies improve printer up-time because the operator has the information to determine if the ink remaining is sufficient to complete the scheduled job(s).

HP 881 Latex Inks contain both liquid and solid components.

Liquid components The ink vehicle is the colorless, liquid component of the inks. It provides reliable, consistent drop ejection by the HP Thermal Inkjet process and carries the ink’s solid components to the surface of the print. Once on the surface, the ink vehicle controls how the ink and media interact. The ink vehicle is evaporated by heaters in the HP Latex 3000 Printer to produce a dry and ready-to-use print.

The physical and chemical properties of the ink vehicle are critical both for drop ejection performance and control of ink-media interactions. These properties are obtained by formulating the ink vehicle with a combination of water, humectants and wetting agents, and liquid additives.

1 Performance may vary depending on media—for more information, see hp.com/go/mediasolutionslocator or consult your media supplier for compatibility

details. For best results, use textiles that do not stretch. The optional ink collector is required for porous textiles on the HP Latex 3000 Printer. 2 Approximately 70% of the weight of the used ink cartridge is a recyclable cardboard container.

Writing system

The writing system of the HP Latex 3000 Printer employs major innovations in printheads, drying and curing, and media advance to achieve high print quality at industrial productivity.

HP 881 Latex Printheads HP 881 Latex Printheads, shown in Figure 8, are a new generation of a printhead design proven to deliver reliable performance with high image quality in HP Latex Printers. HP 881 Latex Printheads have a bi-color configuration with two (2) columns of 5,280 nozzles per color. With 1,200 nozzles per inch, they produce a 4.25-inch (108-mm) print swath. Drop volumes are 12 picoliters for all HP 881 Latex Inks.

HP 881 Latex Printheads incorporate changes to the drop generator design that allow cooler operation. This improves productivity and reduces drop weight variation for better color consistency.17

HP 881Latex Printheads are recyclable through the HP Planet Partners program.18

14 Trademark license code FSC-C017543. 15 HP Latex Inks are GREENGUARD Children & Schools CertifiedSM. See greenguard.org. 16 Unprinted HP Heavy Textile Banner and HP Light Textile Display Banner are Oeko‑Tex® certified according to Oeko‑Tex® Standard 100, which is a globally

uniform testing and certification system for textile raw materials, intermediate, and end products at all stages of production. Tested for emissions of volatile organic compounds and chemical residues such as pesticides, allergy‑inducing dyestuffs, or tin‑organic compounds.

17 The color variation inside a printed job has been measured to be within this limit: maximum color difference (95% of colors) <= 2 dE 2000. Reflective measurements on a 943 color target under CIE standard illuminant D50, and according to the standard CIEDE 2000 as per CIE Draft Standard DS 014-6/E:2012. 5% of colors may experience variations above 2 dE 2000. Backlit substrates measured in transmission mode may yield different results.
