Abstract: Disclosed herein is an electronic digital control system for printing a pattern onto the surface of a moving substrate in accordance with digitally-defined pattern data using a plurality of individually controllable colorant-dispensing applicators arranged in a series of arrays positioned along the path of said moving substrate, with each array containing a colorant representing a separate process color. The digital control system converts the pattern data, expressed in terms of a color assignment for each individual pattern element comprising the desired pattern, into a series of logical firing instructions for each applicator as required to reproduce the assigned color on the substrate using one or more process colors.

Abstract: Method and apparatus for automatically loading at least one look-up table in a textile dyeing system with firing time data. The machine operator enters a list of entries including a base entry, machine color loading entries and a stock entry into the system. A firing time table of firing times is generated for each of a plurality of color bars with respect to a given base, from the base entry. A machine color table of color data is generated for each of the plurality of color bars from the machine color loading entires and a pattern color table of pixel codes and their associated colors with respect to a given pattern is generated from the stock entry. The system correlates the firing times, color data and pixel codes to obtain a modified firing time for each pixel code for each color bar and loads the look-up table with the modified firing time data.

Abstract: A plurality of jet gun bars are spaced apart along the path of travel of a textile material and responsive to pattern data to form patterns on the material. Each gun bar stores and supplies different color dyestuff to color the material. A computer, on each periodic request, supplies pattern data to a predetermined number of gun bars, thereby providing dyestuff to different pattern lines for each request. During a change from printing one pattern to printing another different pattern, for each such request the computer provides data for the other pattern to a first predetermined number of gun bars and data for the one pattern to a second predetermined number of gun bars subsequent to the first number, thereby simultaneously completing the printing of the one pattern and starting the printing of the other pattern.
