Abstract: First, second and third ink ejectors eject ink of three primary colors in superposition onto a sheet of paper being moved relative thereto in response to first, second and third electrical color signals respectively. Circuit means are provided to sense initiation and termination of the signals. Upon simultaneous initiation of one of the signals and termination of another of the signals, the circuit means delays ink ejection from the ejector corresponding to the signal which was initiated for a predetermined length of time. This prevents color mixing at the boundary of the colors which would produce an erroneous color.

Abstract: A method is described wherein quantifiable data which have arbitrary dynamic ranges and which vary as a function of other parameters are represented in color. A set of subranges, without restriction in number, representing data properties are associated with a color set in such a way that the colors are perceived to be maximally differentiable by interpreters, whether human, electronic, or other, by specifically incorporating information concerning the normal or anomalous characteristics of the interpreter's color perception when determing the color set. The method further provides for the realization of color displays by directly associating the colors with densities, transmittances, or illumination levels for negatives, positives, or colored light emitting devices, whether the realization requires primary additive or primary subtractive hues.

Abstract: Disclosed is an apparatus for producing color hardcopy pictorial data recordings.A two-dimensional data frame is displayed on a black-and-white CRT screen and is ultimately recorded on a moving photographic film as a color line, which line is parallel to the horizontal dimension of the CRT screen. The vertical position and intensity of any illuminated phosphor dot in a given horizontal position on the screen determine, respectively, the hue and the intensity of the resolution element in the color line having the same relative horizontal position. The light from the CRT screen is collimated, spectrally dispersed and imaged onto an image plane containing the slit. The elements of the apparatus, including the slit, are relativey positioned so that a particular vertical position on the CRT screen will cause light of a particular color to be imaged onto the slit.
