Abstract
The invention provides an improved ink jet cartridge for an ink jet printer and a method for making the improved ink jet cartridge. The ink jet cartridge includes a substantially inflexible frame having at least one pressure port, the frame having at least one peripheral edge. At least one malleable web is provided having a first side and a second side the first side being attached to the peripheral edge of the frame defining a substantially closed cavity. The malleable web is conformed to the cavity by applying a subatmospheric pressure to the cavity before, after or while heating the malleable web in order to substantially conform the web to the cavity thereby creating a variable volume cavity having a substantially predictable pressure/volume relationship. A biasing element is disposed adjacent the first or second side of the malleable web for biasing the web relative to the cavity. Because the malleable web is conformed to the cavity with heat and differential pressure, ink flow in and out of the ink cartridge is more predictable and the pressure in the ink cartridge is easier to maintained at a desired level thereby improving print quality.
