Four-Part Series: HP Latex 700 W & 800 W. Why Does the “W” Matter?

Previously in this series, Timothy Mitchell discussed how the 800 series differs from the 700 and how the ink and printheads differ compared to previous generations of HP Latex printers. Now, he takes a closer look at the new white ink in the Latex 700 W and 800 W printers.

White ink technology differs from CMYK because it is made from crushed titanium rather than color pigments. If not properly maintained, the white ink can clog. The new HP printers have a system that keeps the white ink continuously circulating. “White ink cannot sit idle so what we have is constant circulation,” says Mitchell. “The whole process [microcirculation] is designed to get white on demand and have no waste or very little waste. The white printheads stay in their rotational chamber until you’re ready to print again.”

It’s not just the microcirculation that makes the HP white ink so popular; it’s also the versatility and vibrance of the output. According to Mitchell, there’s nothing as simple or bright on the market right now. “The white ink is incredibly easy to use; the brilliance is so outrageous. They are flexible and elastic,” he says.

There are several options for printing with white ink. In the video above, Mitchell details over- and under-flood coats, spot color, and 3- and 5-layer printing. He also discusses how to lay down different amounts of white ink depending on what type of graphics you are printing. One of his favorite products for W series printers is HP Matte Polymeric Overlaminate. “HP has the Matte Polymeric Overlaminate as well as the Gloss. You can use them as a laminate, or you can print on them,” says Mitchell. “They both work beautifully and are an absolute ‘go to’ for me on this printer.”

Four-Part Series: Differences Between HP Latex 700 and 800 Series

Recently, we asked Timothy Mitchell to take a closer look at the new HP Latex 700 and 800 Series printers. In this four-part series, he will walk you through the differences between the two series, the innovative ink and printhead system, the new white ink, and he will walk you through the general printer information for all four printers.

Here is a quick overview of the technology behind the new printers. According to Mitchell, this generation is not about making modifications and changing the name. These printers are continuing to build on HP’s success with latex technology. “Almost every part of the printer has been adjusted, improved, updated, and innovated. It’s a new latex introduction,” says Mitchell. “But it still retains the hallmarks of latex: water-based ink, environmentally friendly, and safe for the user.”

Ink Cartridges:

The 800/800 W have 3-liter boxes and a reservoir tank, while the 700/700 W have 1-liter boxes with no reserve. Why does this matter? You get a lower cost per liter and a longer run time. “If you run out of ink in the box, it [the printer] will automatically switch over to the reserve tank,” says Mitchell. “It’s virtually impossible for you to run out of ink while unattended.”

The 1-liter inks in the 700/700 W series is an upgrade over the 775 mL of previous generations, but without the reservoir tank, it is possible to run out of ink if you are doing extended or unattended runs.


While both series are faster than previous models, the 800/800 W is about 15% faster than its counterpart. So why are these printers faster than other generations? According to Mitchell, it’s due to the lower curing temperature. “Instead of printing at 230° F or 240° F, I’m going to be printing at 200° F or less, with more speed,” he says. “So, the prints are coming through quicker and at a lower temperature. More speed and more impact with less thermal deformation.”

Status Beacon:

One very noticeable difference between these two series is the flashing status beacon, a green/yellow/red light on the 800/800 W. Much like a traffic light, this multi-colored light will let you know if the printer is idle (solid green), working (flashing green), needs attention (flashing yellow), or completely stopped and something is wrong (flashing red). The beacon is an excellent way for production managers to run several printers and quickly identify any troubles with the fleet.

These are just a few of the differences. Be sure to click on the video above to learn more about the Latex 800 and 800 W from the 700 and 700 W and check out the HP printers in The LexJet Experience. Check back over the next few days to catch the rest of our four-part series.
