    • A method and apparatus for filling a void in a printed image which has been printed by a thermal transfer printing process employs of a heat-sensitive pigmented material on a foil. A piece of the foil is provided with a dot of the pigmented material having the same color as that bordering the void to be filled and approximately the same size as the void. The foil is positioned on the printed image, with the dot facing and superposed over the void. Heat is applied to the back of the foil, opposite to the dot, while at least the heated portion of the foil is pressed against the image to transfer the pigmented material from the foil to the void in the image. Instead of a dot, the pigmented material can take the form of an image and be transferred from the foil to a receptor material. A heater for simultaneously applying heat and pressure to the foil comprises a handle, a heater element projecting from the handle, and a generally planar registration shield fixed to the handle and resiliently carried in spaced relation to the heater element, such that the heater element may be brought into contact with the shield by pressing the handle toward the shield.
    • 用于在通过热转印印刷方法印刷的印刷图像中填充空隙的方法和装置在箔上采用热敏着色材料。 一块箔片上设有一个着色材料的点,它具有与要填充的空隙相邻的颜色,与空隙大致相同的尺寸。 箔片位于打印的图像上,点的面朝上并叠加在空隙上。 将热量施加到箔的背面,与点相反,而至少箔的加热部分被压靠在图像上,以将着色材料从箔转移到图像中的空隙。 代替点,着色材料可以采取图像的形式并且从箔转移到受体材料。 用于同时向箔片施加热量和压力的加热器包括手柄,从手柄突出的加热器元件以及固定到手柄上的大致平面的对准屏蔽件,并与加热器元件间隔开地弹性地携带,使得加热元件可以 通过将手柄按压到屏蔽上而与屏蔽体接触。

    • In a sprocket-driven plotter, a pair of drive sprockets are spaced apart from each other and keyed to a common sprocket shaft, and a drive motor is drivingly connected to the shaft to rotatably drive the sprockets, and in turn move the sheets engaged by the sprockets relative to a tool carriage for plotting by drawing lines, cutting or performing a variety of other operations on the sheets. A sheet support defines an arcuate support surface fixedly secured to the apparatus, and extending in its elongated direction between the sprockets for conformably contacting the laterally-extending section of each sheet engaged by the sprockets. The arcuate support surface defines a plurality of relatively raised or outermost surface areas, and each raised surface area is defined by an arcuate surface segment extending in the axial direction of the support for contacting and supporting the sheets. Corresponding recessed surface areas are formed between the raised surface areas for reducing friction between the sheets and support.

    • A method and associated apparatus for use in an automated sign generator to produce enhanced special effect graphics and single layer multi-color signs on a vinyl sheet material uses a paint pen carried by the tool head of the generator which in coordinated movement with the vinyl sheet traces the shape of the sign. In one embodiment, the sheet material is cut along a line falling within the painted stripe defining the graphic. The cut graphic having the desired visual special effect is removed from the sheet material along the cut line. The apparatus further includes a guide wheel assembly located between a material deflector and a feed roller for riding along the marginal portions of the sheet material causing it to move along a broken plane path to prevent buckling as it moves relative to the tool head and to prevent smudging of the painted graphic. A cam clip assembly is located behind the feed roller and intermediate the feed roller and a cam shaft and rides along the marginal portions of the sheet material to cause the material to move along a broken plane path to prevent its buckling and avoid smearing of a painted graphic on the surface. A paint pen which is interchangeable with a cutting tool is carried by the tool head and includes a number of interchangeable paint nibs.
