HP Improves Productivity of ElectroInk Manufacturing Process, Reduces Carbon Footprint

Palo Alto, CA, Oct. 16, 2007 - HP today announced that it has improved its manufacturing process for HP 
ElectroInks - the liquid inks used in HP Indigo presses - a change that has yielded significant benefits in 
productivity and energy efficiency.
  
Earlier this year, two HP ElectroInk manufacturing facilities implemented a new particle grinding process that 
reduces the energy consumption by up to 40 percent in the manufacture of the inks. The energy savings comes 
from newly designed custom equipment used in what had been one of the most energy-intensive manufacturing 
steps for HP ElectroInk.

"HP is committed to reducing the carbon footprint of its facilities across the globe," said Alon Bar-Shany, vice 
president and general manger, Indigo division, HP. "Our new HP ElectroInk manufacturing process is an 
excellent example of how HP focuses on smart innovation - investing in research, product development and 
materials in ways to benefit our customers, our company and the environment."

The increase in HP ElectroInk manufacturing capacity supports the continuing, rapid page-growth with HP 
Indigo. According to analyst firm InfoTrends, HP Indigo led the high-volume digital color production market for 
the U.S. and Western Europe(1) regarding unit placements in 2006. The compound annual growth rate for 
page production on HP Indigo presses has exceeded 40 percent for more than three years(2), and ink 
production must scale to meet this trend. 

The two HP ElectroInk plants are based in Rehovot, Israel, and Kiryat Gat, Israel. The HP ElectroInk plant in 
Singapore will also be revamped to adopt the new, energy-efficient manufacturing process.
 
HP ElectroInk is one of the most efficient supplies available in the digital press market. As a liquid ink, it is 
applied in layers that are thinner than what is possible with dry toners. This thin layer not only gives HP Indigo 
presses a level of true offset-quality that is unmatched by other technologies, the volume of ink used is less 
than the amount of dry toner that would be used to create the same image. 

Through an initiative started with the World Wildlife Fund in 2006, HP has pledged to reduce carbon dioxide 
emissions from its operating facilities worldwide. Separately, HP has pledged to reduce its global energy use by 
20 percent by 2010. The new HP ElectroInk manufacturing process supports both of these important HP goals.
