Abstract:
A method of producing a vignette using a single color of ink and preventing barring or banding during a rotary printing operation, the method comprising:moving a substrate in a linear direction with respect to a rotary printing member having an outer surface with a series of elongated printing dots to collectively produce an image on the substrate, said dots having a length extending at least substantially in said linear direction and a width extending perpendicular to said length, wherein said width is less than about 50% of said length and said printing dots on said printing member collectively cover an increasingly larger percentage of the outer surface of the printing member per unit area of said image in a direction parallel to said linear direction, applying a printing medium to the elongated printing dots on said rotary printing member, and transferring the printing medium from said rotary printing member to said substrate to produce said vignette.
