A method for generating data for a jetting program, includes the steps of: a) obtaining substrate data for a substrate, which is to be provided with deposits and components; and b) for each component which is to be placed on the substrate: —fetching component data for the component from said substrate data; and—selecting a matching predefined deposit pattern, comprising at least one deposit, which matches a desired deposit pattern for said component data, wherein the deposit pattern comprises, for the/each deposit, deposit data comprising deposit extension and deposit position; or—if no matching predefined deposit pattern exists, defining a deposit pattern, comprising at least one deposit, for the component data, comprising the step of defining, for the/each deposit, deposit data, which step comprises determining deposit extension and deposit position.
