Abstract
The present invention relates to methods for imprinting solid particles onto materials that enhance the performance characteristics, such as the odor adsorption capacity, of the material. The present invention uses a xerographic imprinting method to apply a toner formulation to the material. The toner formulation typically includes solid particles (e.g., activated carbon), binding agents, and additives. Using this method, a specific pattern can be imprinted onto the material. The present invention can also use a Gravure method to imprint performance enhancing solid particles onto a material. This method advantageously provides precise control over the volume of mixture (e.g., solid particles and binding agent) impressed onto the material. In addition, this method can imprint specific patterns of mixture onto the material.
