An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration on a predetermined surface of a metallic container body. The decoration may be registered with decorations previously applied to the container body. In one embodiment, the apparatus includes a screen print unit with a cylindrical body. The cylindrical body rotationally applies a predetermined type or color of ink or other coating, such as a varnish, to the cylindrical body. In one embodiment, the apparatus applies a varnish to a selected portion of the cylindrical body without applying the varnish to all of the cylindrical body. Additionally, the apparatus may also include a foiling unit that applies a label to the cylindrical body.

A multi-step process involves formulation and treatment of silicone to break the surface tension transforming silicone texture from traditional rubbery-feeling to smooth satin finish. A low viscosity, translucent silicone rubber compound is separated and cured at room temperature. Part A (Base) is modified to include silicone thinner. Part B (Catalyst) is modified to include retarder. Both Parts A and B are weighed to equal parts. Part A is further modified by including color pigment and colorized mica powder. Parts A and B are mixed at a 1:1 ratio. This formulated silicone is poured into a syringe and applied to hand-painted silk fabric to create scarf border and decorative design. Silicone is allowed to set. Silicone is then treated by: (1) applying 170 heat for period of time, contingent on air temperature and humidity; and (2) dusting and lightly brushing the silicone with a 50/50 mixture of mica and rice powder.
