A composition is provided consisting of an aqueous solution comprising at least one natural polysaccharide or a derivative thereof and at least one polymeric polyamino compound, the composition being capable of forming a film when applied onto a substrate. The inner boundary is defined at least in part by a hub structure that has an upstream end and a downstream end. The stencil printing machine further includes a discrimination device for discriminating a type of the stencil sheet roll in accordance with the measured position of the target or in accordance with the obtained color information of the target. The status section of a cell comprises a control unit coupled to a status input, to a status output and to a clock input, and generates an output clock signal, which controls charge controlling elements coupled to the status input and the status output and controls the data section. In this manner hash collisions are avoided and the size of the memory is not a function of the degree of multi-way set-associativity used.
