    • A thermal printer capable of preventing crease formation in a dye transfer area of a dye donor web that can cause a line artifact to be printed on a dye receiver during a dye transfer from the dye transfer area to the dye receiver, includes a print head having a bead of selectively heated resistive elements that make contact across the dye transfer area of the dye donor web and opposite edge areas of the dye donor web that are alongside the dye transfer area as the dye transfer area and the edge areas are progressively advanced under a longitudinal tension over the bead of resistive elements. Also, a control is adapted to selectively heat those resistive elements that make contact with the dye transfer area to effect a dye transfer from the dye transfer area to a dye receiver, and adapted to variably heat those resistive elements that make contact with the edge areas alongside the dye transfer area to effect a gradual drop in heat substantially from respective boundaries between the dye transfer area and the edge areas to an outer edge of each edge area that is spaced from the dye transfer area. As a result, when the heated transfer area and edge areas are subjected to a longitudinal tension, a relative resistance to being stretched will steadily increase towards each outer edge to maintain strength at each outer edge, but to avoid a sharp transition at the boundaries in order to prevent crease formation that can cause a line artifact.
    • 一种热敏打印机,其能够防止染料供体纤维网的染料转移区域中的折痕形成,所述染色剂供体纤维网在从染料转移区域到染料接收器的染料转移期间可能引起线伪影印刷在染料接收器上,所述打印头具有 选择性加热的电阻元件的珠粒,当染料转移区域和边缘区域在染色体转移区域的边缘区域逐渐进行时,使得在染料供体幅材的染料转移区域和染料供体幅材的相对边缘区域之间接触, 电阻元件珠的纵向张力。 此外,控制器适于选择性地加热与染料转移区域接触的电阻元件,以实现从染料转移区域到染料接收器的染料转移,并且适于可变地加热与边缘区域接触的那些电阻元件 沿着染料转移区域,从而基本上从染料转移区域和边缘区域之间的相应边界逐渐降低到与染料转移区域间隔开的每个边缘区域的外边缘。 结果,当加热的传送区域和边缘区域受到纵向张力时,相对于被拉伸的相对阻力将朝着每个外边缘稳定地增加以保持每个外边缘处的强度,而是避免在边界处的边界处的尖锐的过渡 以防止可能导致线条伪影的折痕形成。

    • A method for determining a mismatch involving the availability of a dye donor supply and a dye receiver supply in a thermal printer when a particular print size and print quantity are selected, comprises: comparing a remaining number of similar-size donor patches available on the dye donor supply with a remaining number of like-size donor patches required for the selected print size and print quantity, and should the former number be less than the latter number providing a warning; and comparing a remaining length of dye receiver available on the dye receiver supply with a remaining length of dye receiver required for the selected print size and print quantity, and should the former length be less than the latter length providing a warning.
    • 当选择特定的印刷尺寸和印刷量时,用于确定涉及染料供体供体和热敏打印机中的染料接收器供应的不匹配的错误的方法包括:比较可用于染料上的相似尺寸供体贴片的剩余数量 捐赠者供应剩余数量的所需打印尺寸和打印数量所需的相同尺寸的捐助者补丁,前一数字应小于后一个数字提供警告; 并且将染料接收器供应器上可用的染料接收器的剩余长度与所选择的打印尺寸和打印量所需的染料接收器的剩余长度进行比较,并且如果前一个长度小于后一个长度,则提供警告。
