Everything you need to know About HP Latex Inks
Find out how our versatile HP Latex Inks can help you deliver sustainable, high-quality print solutions to customers.
Print professionals need a better way
Customers and businesses are demanding more from their prints than ever before, and it falls on print businesses to keep up with these evolving expectations. They need a better solution: one that’s durable, provides versatile media options, and is fast to print.
HP LATEX: DESIGNED TO MEET TODAY’S NEEDS
At HP, we’ve refined our Latex technology over the last decade to match your business’ challenges. After drawing on our deep experience in the industry, we’ve created HP Latex Inks to meet the demands print businesses face today: delivering a saleable output quickly. This doesn’t just mean fast printer speeds on standard substrates, it also means having the versatility to deliver on increasingly diverse print requests from customers.
Environmental concerns and using a wider range of printable materials are high on the agenda for print buyers. As a print provider, making informed decisions about your printer investments is growing in importance, right down to the versatility and performance of your printer inks.
The science behind HP Latex Inks
What makes HP Latex inks different?
HP Latex Inks consist of up to 65% water and are designed to avoid the hazards associated with eco-solvent and UV inks.
They contain zero Hazardous Air Pollutants (HAPs),1 are non-flammable and non-combustible.2 They don’t require any special ventilation,3 don’t release ozone, and avoid the problematic reactive monomer chemistry.4
The liquid ink vehicle is mostly made up of water, a wetting agent, and a humectant (a substance that prevents moisture from escaping the mixture).
This vehicle is needed for printhead reliability, and a similar compound is found in all sorts of printers—from the ones in your home to industrial presses. It carries the pigment particles (pink) and latex polymer (dark blue) through the printheads and onto the substrate, where theythen form your desired image.
THE UNIQUE TWO-STEP PROCESS
HP Latex technology uses a process called Aqueous Dispersion Polymerization (ADP) to produce high-quality, long-lasting prints. ADP printing is split into two distinct phases: application and drying.
It’s these phases that give Latex prints their unique properties and make them highly durable.
SO, WHAT’S THE RESULT?
Once the latex layer is activated, the pigments and substrate leave a durable image on the print media surface. Prints are ready to use, even laminate, the instant they leave the printer’s output tray.
The process helps speed up your workflow as it requires minimal cleaning. This is thanks to the ink formula’s unique properties, as well as the way it interacts with our proprietary monitoring hardware. This intelligent ink application system means you can cut down on maintenance times—giving you the upper hand when it comes to delivering multiple quick turnaround jobs.
How HP Latex Inks perform in the real world
How can HP Latex inks improve versatility across real world applications?
Our inks have been designed to perform both indoors and outdoors and withstand physical and chemical damage. But don’t just take our word for it: HP Latex Inks have been independently certified by industry-leading labs to deliver outstanding health, safety, and environmental performance. Here’s how you can meet your goals and deliver better products for your customers.
Deliver confidence in your sustainability credentials
The businesses you work with—and importantly, the end users they deliver to—are focusing on their environmental impact more than ever before. Many are now rolling out ambitious sustainability roadmaps, and they’re thinking more carefully about where their printed media comes from.
The latest generation of HP Latex Inks are UL ECOLOGO certified 5, which means they meet a range of stringent environmental performance standards and human health criteria, and are also UL GREENGUARD Gold certified.
In addition, HP Latex Inks are fully compatible with a range of FSC-certified papers and PVC-free solutions,6 which offer alternatives to the use of problematic plastics in print.
Our HP Latex 700 and 800 Printer series inks are ENERGY STAR accredited for their energy efficiency. Their chemical composition is certified by the Zero Discharge of Hazardous
Chemicals Foundation (ZDHC) and meet the standards of its Manufacturing Restricted Substances List (ZDHC MRSL), ensuring safe disposal of both ink cartridges and
The Electronic Product Environmental Assessment Tool (EPEAT) is a procurement certification that helps purchasers choose products that align with their environmental goals.
All printers in the HP Latex range are EPEAT-registered (where supported), so our customers can compare printer performance against widely-recognized sustainability criteria.

Health and safety is a growing concern
ADDRESSING THE RISKS
The latest water-based HP Latex Inks are designed to avoid the hazards associated with solvent, eco-solvent, and UV inks, and their low emitting prints give them a major advantage over traditional solutions. Their odorless10 prints make them ideal for practical applications in sensitive areas—including education and healthcare facilities.
HP Latex Inks meet indoor air quality standards for low chemical emissions during print usage. They are UL GREENGUARD Gold certified5 low emitting as ‘Unrestricted’ for a fully decorated room 33.4 m2 (360 ft2) in an office environment and 94.6m2 (1,018 ft2) in a classroom environment.
Prints produced using HP Latex Inks on HP PVC-free wallpaper meet AgBB criteria for health-related evaluations of VOC emissions of indoor building products. They are also rated
A+ (very low emission) according to the “Émissions dans l’air intérieur” statement on the level of volatile substances in indoor air.
Customers need durable solutions
Durability is the ability to withstand wear and tear from different sources of degradation when prints are exposed to various environmental conditions. There are three key components that make a product durable: light-fade resistance, scratch and abrasion resistance, and water and chemical resistance.
Light-fade resistance, sometimes referred to as print permanence, is a measure of how well a print resists fading with exposure to light and other environmental factors such as ozone. The color of an ink comes from its dyes or pigments, and over time these particles will be broken down by UV rays in sunlight, resulting in colors that fade.
In the table below, we’ve highlighted the expected life of prints produced with our HP Latex 700 and 800 Printer series inks, so you can visualize how these would stand up in a typical business, retail, or education setting.
SCRATCH AND ABRASION RESISTANCE
Scratch and abrasion resistance refers to a print’s resistance to damage from different objects with which it comes into contact.
Scratch damage refers specifically to damage from sharp or pointed objects—fingernails, for example. This is a very important consideration for high-value prints that will be
viewed at short distances since a single scratch can occur in an instant and permanently damage a print. Additionally, once they’ve been damaged, the print could be prone to further peeling and degradation.
At HP, we perform all our scratch and abrasion testing with a taber tester, calibrated to industry-standard levels.
Abrasion (also called dry rub) refers to damage caused by repeated rubbing in the same location. This is an important consideration for mid-to-long-term graphics that will be handled frequently.
WATER AND CHEMICAL RESISTANCE
Water and chemical resistance refers to the ability of a graphic to resist water, cleaning products, and other chemicals. For example, graphics in some indoor locations may be cleaned with water and other detergents, and vehicle graphics undergo frequent washing or sporadic fuel spills. To test performance in this area, HP performs wet rub testing
with water, as well as a common cleaning product—Windex® window cleaner.
In the table below, you can see how HP Latex Inks resist scratch, abrasion, water, and chemical cleaner damage. Once again, we performed these tests on materials that had been printed on with HP Latex 700 and 800 series inks. The following results are an average of all the materials tested, and reflect the most common behaviors, so you can understand how they perform in a typical real-world environment.
SO, TO RECAP:
• HP Latex Ink’s unique chemical composition delivers durable images that are ready to laminate immediately.
• The ADP process reduces cleaning time and streamlines your workflow.
• HP Latex Inks provide the environmental credentials to give your customers confidence in your eco-conscious products.
