(57) A silicone membrane collector is disclosed which is formed of room temperature vulcanizing
rubber. The silicone membrane receives or collects, by intimate contact, a thermoplastic
pressure-sensitive ink formulation in the form of one or more portions of a design.
The design thus collected may be deposited onto another surface by intimate mechanical
contact of the membrane therewith. The membrane may be between 0.2" (6.08 mm) and
0.02" (0.508 mm) thick, and may be formulated to have a tensile strength of at least
50 psi (3.45 bars), an elongation of at least 150% and a surface tack of between 20
and 1200 g.
