    • In one aspect of the invention there is disclosed a multicolor thermal imaging system wherein different heating elements on a thermal print head can print on different color-forming layers of a multicolor thermal imaging member in a single pass. The line-printing time is divided into portions, each of which is divided into a plurality of subintervals. All of the pulses within the portions have the same energy. In one embodiment, every pulse has the same amplitude and duration. Different colors are selected for printing during the different portions by varying the fraction of subintervals that contain pulses. This technique allows multiple colors to be printed using a thermal print head with a single strobe signal line. Pulsing patterns may be chosen to reduce the coincidence of pulses provided to multiple print head elements, thereby reducing the peak power requirements of the print head.
    • 在本发明的一个方面,公开了一种多色热成像系统,其中热打印头上的不同加热元件可以在单次通过中在多色热成像构件的不同成色层上印刷。 行打印时间被分为部分,每个部分被分成多个子区间。 部分内的所有脉冲具有相同的能量。 在一个实施例中,每个脉冲具有相同的幅度和持续时间。 通过改变包含脉冲的子区间的分数来选择在不同部分期间进行打印的不同颜色。 该技术允许使用具有单个选通信号线的热打印头来打印多种颜色。 可以选择脉冲图案以减少提供给多个打印头元件的脉冲的一致性,从而降低打印头的峰值功率要求。

    • In one aspect of the invention there is disclosed a multicolor thermal imaging system wherein different heating elements on a thermal print head can print on different color-forming layers of a multicolor thermal imaging member in a single pass.
