Want to increase your Bubble Jet IQ ? Come on over >>  Multiple-Value Expression Technology for Photo-Quality Images Conventional ink-jet printing systems are based on the principle of two values for each ink color: eject no ink or eject ink. This method falls to adequately produce natural, smooth color gradations. Photograph images, however, require reproduction that captures subtle color tone changes, such as in pictures of the sky. With Canon's "multiple-value expression technology," size, density, printing pattern and other factors controlling each ink droplet are optimized to allow a wide variety of densities to be selected for each pixel. The effect is equivalent to having multiple ink densities for each color. In the BJC-8200, we used a combination of regular inks and 1/6th-density photo inks. We also incorporated MicroFlne Droplet Technology, which produces ultrafine 4-pl ink droplets. As a result, we achieved a maximum of 33 color gradations per pixel, enabling us to faithfully render prints ranging from extremely light tones to medium-weight and heavy, high-density colors. This achievement, which cleared one of the major obstacles to photo-image output from inkjet printers, expresses such color subtleties as the sheen of a person's skin, the transparency of glass and water, and the luster of a metal surface in natural color gradations.  |
