Abstract

A method for quality inspection of nozzles of an ink-jet print module. The method comprises: forwarding a paperboard web continuously at a substantially constant speed in a machine direction; printing a decor layer on the paperboard web using the print module; and printing a test pattern comprising a test element on the paperboard web by activating a plurality of the nozzles, which are intended to be inspected. The test pattern has a fixed position in relation to the decor layer, and is indicative of the quality of each nozzle of the plurality of nozzles.
