Abstract:
1. A method for manufacturing an ink cartridge comprising the steps of: connecting at least one film to a frame, wherein the at least one film and the frame define an ink chamber therein, and the ink cartridge comprises the at least one film and the frame; positioning a patterned member adjacent to the at least one film, wherein the patterned member comprises a first pattern, and the first pattern comprises a first portion and a second portion which is raised with respect to the first portion; and forming a second pattern corresponding to the first pattern on the at least one film by generating a pressure differential between a pressure inside the ink chamber and a pressure outside the ink chamber, wherein the pressure differential draws the at least one film into contact with at least a portion of the first pattern, and wherein the step of forming the second pattern comprises the substep of reducing the pressure outside the ink chamber.
