Multicomponent superabsorbent gel particles are disclosed. Certain embodiments of the system and method utilize image processing techniques to determine the various exposure settings and to form the optional composite image. The voids are formed to extend through less than the entire thickness of the layer where they are being formed. Advantageously, a microfluidic device may thereby be instructed to perform an intended reaction or analysis by invoking micro-droplet control function that perform intuitive tasks like measuring, mixing, heating, and so forth. A corrected road map of the vessel system is interpolated from the exposures at the end of inspiration and the end of expiration and the exposure of the intervention device is superimposed on the corrected road map. The rotary shaft of the shutter is positioned to return the shutter to an initial position by being rotated in an opposite direction by its own weight after the paper has passed through the nip of the roller.
