Abstract: A milling system for milling an edible input material into an edible product configuration meeting a product specification includes a plurality of mills arranged in parallel and connected by recycle loops. A measurement system is provided for measuring attributes of the mills and attributes of the edible input material upstream and downstream of the mills. A continuously self-learning control system is provided for performing operations based on a continuously self-learning algorithm. The operations include processing measurement data of the measurement system to control the mills while maximizing particle sizes in the system, and receiving an operator selection identifying the edible input material to be milled and the edible product configuration to be produced by the milling system. The control system initializes and operates the mills based on an initial control model of the milling system associated with the selection, and continuously updates the control model and mill settings.

Abstract: A method of determining multi-level printing parameters for a printing device includes identifying printing parameters for each of multiple colorant levels; providing at least one density measurement at a known coverage for each colorant level; providing an aim curve relating input tone value to printed density value; and identifying multiple test parameter sets. The method further includes, for each of the test parameter sets at each of multiple input tone values, determining a printed density value based on the parameters of the test parameter set and the density measurements, and determining an error value from differences between the determined printed density values and the aim curve. The method also includes selecting one of the test parameter sets using the determined error values; and communicating the selected one of the plurality of test parameter sets for receipt by the printing device for printing documents. Systems and software can employ the method.
