–"Level Color" printing–
“Level Color” printing developed to substantially reduce the use of ink without compromising legibility
- Japan/Ricoh Co., Ltd.
Ricoh’s GELJET printer employs GELJET technology for high-quality, high-speed and high-color printing on plain paper, a requirement at offices. In 2004, the company independently developed “Level Color” printing technology to reduce the use of ink for images (photos, illustrations, graphs, etc.) without changing the amount of ink used for text, thereby making it possible to output color prints using an amount of ink equivalent to that used for monochrome printing. Subsequently, the technology was further advanced to make color printing more economical while maintaining the legibility of text and images. Specifically, utilizing the fact that the sensitivity of the human eye to colors varies depending on the color, the amount of ink for colors whose legibility does not depend on the color strength is reduced. This advanced “Level Color” printing technology was first applied to the IPSiO GX e3300 released in May 2009 and then also applied to the subsequently released IPSiO GX e2600, IPSiO GX e5500, and IPSiO GX e7700.
These models are also equipped with a newly developed ink feeding system, which has greatly improved ink cartridge use efficiency. Ricoh will continue to develop product technologies and help customers reduce their environmental impacts.
