Abstract

There is shown and described a process for making multi-hue thermal transfer ribbon where the color stripes are parallel to the axis of ribbon wind. The multi-color ribbon is produced by a thermal transfer method using solid color ribbons.

Multi-hue Ribbon Manufacturing Process

There is shown and described a process for making multi-hue thermal transfer ribbon where the color stripes are parallel to the axis of ribbon wind. The multi-color ribbon is produced by a thermal transfer method using solid color ribbons.

The figure is a schematic illustration of the process. The substrate 2 on which the multi-hue ribbon will be formed travels from supply 4 through a series of ink transfer stations 6 to takeup 7. Within any given transfer station 6 the unslit substrate passes through a drive roller pair to a chill station 8. Sensor 10 is provided to indicate to the system the appropriate time to bring the colored donor ribbon 12 from supply 14 into contact with the substrate 2. Donor ribbon 12 is heated by means of roller 18 to a temperature at which the color ink is softened and nearly liquified. The chilled substrate is brought into contact by the downward motion of a drive roller for a period determined as a function of the height of that color ink zone needed on substrate 2. During this contact period, the resin-based ink cools and solidifies on the chilled substrate 2, removing all ink from the colored donor ribbon 12.

It should be noted that, in use, multiple transfer points may be provided at a single station. Alternatively, an extended flat heating surface may be used with a plurality of contact points for the substrate 2 as it emerges from a chilled zone above the heated surface.
