Abstract:
A method of forming a chemical delivery device with an active chemical includes generating halftoned image data using a stochastic halftone screen and with reference to a concentration parameter for the active chemical. The method also includes ejecting a chemical carrier including the active chemical into a portion of a plurality of cavities formed in the chemical delivery device based on the halftoned image data to produce the chemical delivery device with a concentration of the active chemical corresponding to the concentration parameter.
