  • Method and apparatus for producing four colors by solid application of only two coloring media
    Patent number: 7237862
    Abstract: Processes for producing specified solid colored patterns and devices for the production of such patterns can be used to evoke the appearance of a color other than the colors that would be produced by simple solid application of the colorants used. Thus, for example, a printing process used for package printing, can print a four-color package using a two-color press and inks of only two colors, without the use of a halftone process.
