    • According to the present invention a method is disclosed for making a negative-working, heat-sensitive printing plate precursor capable of switching from a hydrophilic state into a hydrophobic state upon exposure to heat and/or infrared light, comprising the steps of (i) providing a support having a surface comprising titanium, (ii) modifying said surface by producing an oxide of titanium following the steps of (1) anodizing said support and (2) annealing said anodized support under reduced pressure.
      According to the present invention there is further disclosed a method for making a negative-working, heat-sensitive printing plate precursor capable of switching from a hydrophilic state into a hydrophobic state upon exposure to heat and/or infrared light, comprising the steps of (i) providing a support having a surface comprising titanium, (ii) modifying said surface by producing an oxide of titanium following the steps of (1) etching said support and (2) anodizing said etched support.

    • A dot matrix printing method is provided for printing an image on a printing medium with reduced banding, by moving, with respect to the printing medium, a printing head in a fast scan direction during a plurality of printing passes. The method comprises the step of writing the image during the plurality of printing passes by mutually interstitial printing steps and/or interlacing steps, wherein the writing step comprises moving the printing medium with a transport distance step in a slow scan direction perpendicular to the fast scan direction between the printing passes of the at least two sub-images. The sum of all transport distance steps after writing one swath of each sub-image is exactly one head length, and the transport distance steps are performed in at least two different step lengths.
    • 提供了一种点阵打印方法,用于通过在多次打印通过期间以快速扫描方向相对于打印介质移动打印头,在具有减小的条带的打印介质上打印图像。 该方法包括通过相互间隙打印步骤和/或交织步骤在多个打印过程中写入图像的步骤,其中写入步骤包括以垂直于快速扫描的慢扫描方向的传送距离步长移动打印介质 所述至少两个子图像的打印遍之间的方向。 写入每个子图像的一个条之后的所有传送距离步长的总和恰好是一个头部长度,并且以至少两个不同的步长执行传送距离步长。
