Visual indicia or patterns are produced as each of the successive increments extending across a continuously advancing web of paper or fabric is imprinted with a series of visual dots from a sheet or ribbon containing a visual medium by at least one closely packed series of elements that are selected instantly by electronic logic, energized simultaneously by electrical pulses, and recycled rapidly by a common electrical and thermal bus. Specified parameters have been found to combine rapid advancement of the web and close packing of the visual dots.
