A method of processing print jobs on a printing substrate processing machine by using a computer, includes creating a data model for the computer with parameters for an unusable print/set-up time prediction on the basis of global print jobs and printing machine data, training the data model on the basis of global and/or local print jobs and printing machine data by using the computer, and defining ease-of-use criteria by an operator. The trained data model for the computer is used to predict the number of unusable prints during set up and set-up time of the printing substrate processing machine. The order of the processing of the print jobs is optimized on the basis of the predicted number of unusable prints during set-up and the predicted set-up time by using the computer.

The invention concerns a spray nozzle for a powder duster for dusting freshly printed products with a connection for a tube for supplying a powder-air mixture, a distribution chamber and at least two nozzle channels which branch off from the distribution chamber like a fan, wherein the opening angle of the outer nozzle channels limiting the fan subtends an angular range of 5&#xb0; to 20&#xb0;, in particular an angular range of 8&#xb0; to 15&#xb0;, and preferably 12&#xb0;. The invention also concerns a spray bar with spray nozzles of this type, a powder duster comprising spray nozzles of this type, and a method for dusting freshly printed products.
