Abstract
Recording media press systems and methods of operating such press systems. Press system embodiments include a first foil holder coupled to a first die, the first foil holder including a plurality of first tabs extending radially inward from the first die to clamp first portions of an outer perimeter of a first embossing foil against a surface of the first die and a second foil holder coupled to a second die, the second foil holder including a plurality of second tabs extending radially inward from the second die to clamp second portions of an outer perimeter of a second embossing foil against a surface of the second die. In an embodiment, the first and second outer perimeter portions are complementary arc segments to interdigitate the plurality of first tabs with the plurality of second tabs when the press is closed.
