E-reader manufacturer iRex have announced [pdf link] that they intend to have a color, writable ebook reader on the market by 2011. The device, which is currently unnamed, will use a system of subtractive color mixing which, according to iRex, results in three times the brightness of existing additive color electrophoretic displays.
Details on the subtractive e-ink technology are scant, but it is compared to physical printing whereby colors act as filters to absorb portions of white light striking them and reflect back the desired hue. The additive system, meanwhile, mixes together backlit or illuminated colors to create hues, often requiring filters that can reduce overall quality.
iRex believe that their subtractive e-ink displays will offer print-quality visuals to magazines and other full-color publications, and push them ahead of the crowd. Meanwhile color e-paper producers have reportedly delayed their launches to 2010, in the face of technical issues.

iRex Technologies Developing a High Quality, Full Color Digital
Eindhoven, 2 June 2009 ‐ The world’s leading provider of e‐reading solutions, Netherlands‐based iRex Technologies (www.irextechnologies.com), announced new progress on development of a next generation of color, writable ultra‐thin digital readers expected to launch mid 2011. This news reaffirms and substantiates iRex’s position as a leading innovator in the digital reading market following their 2008 launch of the iRex DR1000. Leading the way for others, the DR1000 was the first commercially available ‘writable’ digital reader with a 10.2 inch screen.
Speaking at the Society for Information Display (SID) conference in San Antonio, TX (USA), iRex’s leading display expert Alex Henzen, confirmed the company’s commitment to push the boundaries of electrophoretic display technology in order to meet consumer demand for competitively priced, high quality digital readers.
“The ultimate goal of an electronic paper display is to mimic the appearance of pigment on paper. This means more than just bright color, the reflection also has to be diffuse,“ explained Henzen. “iRex’s subtractive color mixing technology will allow us to produce a wide range of colors in high resolution to deliver magazine‐quality color to our e‐reader customers.
The current color solution for electrophoretic displays – those displays universally found in e‐readers ‐ employ additive color mixing techniques and filters that compromise the reading quality of the display. The new iRex solution will be based on subtractive color mixing similar to physical printing which will offer three times the brightness of current color prototypes.
“iRex is in constant dialogue with its customers and partners. As a result, iRex was the first to recognize the demand for a writable large screen reader allowing full page PDF files and e‐newspapers to retain their original look, feel and layout. The next step is color,” comments Willem Endhoven, VP of marketing and business development at iRex Technologies. “It is our mission to innovate with our partners and support them in delivering their content in the best possible way to their target audience. A high quality color solution will open the gates for color rich periodicals to publish their content on the electronic paper platform.”
