Abstract
A method includes moving a multi-color ribbon over a target object. The multi-color ribbon has a lower layer and an upper layer of inks or pigments. The method also includes applying heat and pressure onto the multi-color ribbon to transfer the overlying layers of the inks or pigments to the target object, and removing at least a portion of the lower layer of the ink or pigment that was transferred to the target object to reveal at least a portion of the upper layer of the ink or pigment that were transferred to the target object.
Claims22
A multi-color, hot stamp printing method comprising:
- moving a multi-color ribbon over a target object in a single pass over the target object, the ribbon having different non-overlapping areas with each of the areas containing an ink or pigment of a different color than the other ones of the areas, each of the areas extending end-to-end along a length of the ribbon;
- and
- striking two or more of the different areas in the ribbon with a die while the ribbon is moved over the target object in the single pass,
- wherein the die strikes the two or more of the different areas to simultaneously transfer differently colored inks or pigments in the two or more of the different areas to the target object at the same time.
A hot stamp printing method comprising:
- moving a multi-color ribbon over a target object, the ribbon having an elongated carrier that continuously extends from a first end to an opposite end, the ribbon having different non-overlapping areas that each extend from the first end of the ribbon to the opposite end of the ribbon, the areas in the ribbon having differently colored inks or pigments on the elongated carrier;
- and
- striking two or more of the areas in the ribbon with a die from a hot stamp printing system during a single pass of the ribbon over the target object to simultaneously transfer two or more of the differently colored inks or pigments to the target object at the same time.
