Breakthrough in inkjet color number

The number of colors is one of the most important parameters of jetting. It was originally composed only of three colors of red, yellow, and blue, and three-color intermodulation was used to obtain color effects. Due to the higher cost of printing black-and-white text with a three-color ink cartridge, there has been a subsequent increase in the cost of text printing by the addition of a black ink cartridge.

Most low-end products use this four-color approach. But in this way, there is no substantial improvement in the effect of color, so in order to pursue a more perfect printing effect, the number of colors will be continuously increased to five colors, six colors, seven colors, eight colors, so that with the June of this year HP's photosmart 8758, the color inkjet has increased the number of colors to nine colors.

The machine uses nine types of hp vivera ink, including magenta, light magenta, cyan, light blue, yellow, dark gray, light gray and photo black and blue, and is divided into three ink cartridges, among which the newly added blue Ink increases the blue hue by 25%, making it more vivid when printing any dark blue photo.

From a practical point of view, the current six-color products on the market can fully meet the needs of families, and eight-color products can also meet most of the professional needs. From the brand point of view, the pursuit of color is not the same for each business.

Taking eight colors as an example, hp added a light black color to the original seven-color ink, making the gradation effect more outstanding when printing images; epson uses red, blue, bright color, yellow, magenta, respectively. Eight colors, such as cyan, matte black, and photo black, make it more advantageous for displaying character colors, indoor scenes, and architectural scenes. The canon adds the most common green in the natural world based on the original magenta, yellow, blue, light magenta, light blue, orange, and black colors of the seven-color ink cartridge technology, making it more effective in displaying natural scenes. .

In addition, from the effect point of view, HP's black and white printing is very unique, Epson is more true in the true color reproduction, Canon is printing a bright color effect, a good sense of color.
