A SAN management agent computes a validator corresponding to a full data set from which a relative data set is derived. The print pattern is obtained by being printed by using an optional printing ink or inks of blue, yellow, red black and white inks or an ink or inks prepared by blending the printing inks. Additional embodiments include a fore compartment and an aft compartment sealed by a septum. The inkjet printing process may include the step of printing a plurality of layers, wherein a first layer includes at least one electronic ink deposited directly onto the substrate, and wherein each subsequent layer includes at least one electronic ink deposited on top of at least a portion of a previous layer when the previous layer has been cured.
