The invention concerns a device and a method for creating a saliency map of an image. A preamble section including signaling information and a data section including at least one data stream are generated. The apparatus also includes a barrier member surrounding a space between the projection system and, in use, the substrate, to define in part with the final element a reservoir for liquid. Then, the cross-linked polymeric composite undergoes a simple-sheared process and turns into a polymeric composite with a strain more than 1%.
