Abstract
A method and apparatus for printing a multi-color ink pattern on a substrate surface which comprises arranging a series of patterned surfaces with each patterned surface having a pattern that is unique to one of the colors and that corresponds to the pattern of that color in the multi-color pattern, supplying to each patterned surface a radiation-curable ink formulation, having an appropriate colorant to form an ink pattern thereon, transferring individually the color pattern from each patterned surface to a collector roll, increasing the cohesiveness of the ink sufficiently to permit complete transfer of the pattern, forming a composite of the color patterns on a collector roll, and transferring the composite pattern in its entirety to the substrate surface.
