  • Method and apparatus for controlling the size of dots produced by jetting phase change ink
    Patent number: 4745420
    Abstract: A method of ejecting droplets of phase change or hot melt ink jet ink upon a target such as paper includes a step of applying pressure to the droplets after they have cooled upon the paper in order to increase their coverage and, thus, minimize the volume of ink required to produce a high quality print with a high degree of resolution. Including a means for applying pressure to the cooled droplets, a suitable apparatus increases the area of the target covered by a particular droplet after spreading by at least five percent and preferably by twenty percent.
