A micro-contact printing apparatus includes a roller (100, 200, 300) with a gas filled volume (220, 320) that deforms to provide a more uniform and better-controlled surface pressure for a deformable stamp roller surface (240, 340). In one approach, a gas-filled volume (220) is provided in a deformable gas-tight material (225) within a cylindrical support (210). Mechanical supports (230, 234, 241, 246, 251) such as pins couple the stamp roller surface (240) to the deformable gas-tight material (225). Or, the gas filled volume (320) may be provided between a gas-tight cylindrical support (310) and a stamp roller surface (340). Mechanical supports (330, 332) such as folded blades, couple the stamp roller surface (340) to the cylindrical support (310) while preventing lateral movement of the stamp roller surface relative to the cylindrical support. Active control (130) of the pressure in the gas filled volume may also be provided.
