Provided is a method for embedding information on a substrate comprising:
converting information to machine readable code, wherein the code comprises a set of intended printed markings, wherein each intended printed marking of the set has a predetermined height on a substrate and represents a predetermined value, wherein intended printed markings having a same predetermined height represent a same data value, and wherein intended printed markings representing different data values have different heights; and
printing the machine readable code on the substrate by depositing an ultra-violet curable phase change ink comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant and curing the deposited ink, such that each of the intended printed markings is printed to have the predetermined height.
提供了一种在基板上嵌入信息的方法,包括
将信息转换为机器可读代码,其中代码包括一组预定印刷标记,其中该组预定印刷标记中的每个标记在基板上具有预定高度并代表预定值,其中具有相同预定高度的预定印刷标记代表相同数据值,而代表不同数据值的预定印刷标记具有不同高度;以及
通过沉积紫外线可固化相变油墨在基板上打印机器可读代码,该相变油墨包括可选
着色剂和相变油墨载体,后者包括可辐射固化的单体或预聚物;光
引发剂;活性蜡;和胶凝剂,并固化沉积的油墨,从而使每个预定打印标记具有预定高度。
