Abstract

This article relates generally to processes and apparatus for fabricating multi-color inked ribbons and more particularly to the formation of ink impermeable barriers which prevent the colored inks from bleeding into one another by means of ultrasonic heating. The above figure shows a nylon printing ribbon 1 as it passes over a metallic comb 2 and beneath an ultrasonic horn 3. As ribbon 1 passes over teeth 4 of comb 2, horn 3 applies ultrasonic energy to ribbon 1 causing the nylon fibers thereof to fuse where ribbon 1 tangentially touches teeth 4 forming a plurality of fused stripes 5. The latter act as barriers to prevent the bleeding of different colored inks into one another when subsequently deposited onto ribbon 1 in the regions between stripes 5.
