A method for preparing a lithographic printing plate by means of ink jet printing. The target sequence is a splice variant of PDE5 called a PDE5a1, a component of which is presented as SEQ ID No 1. The timing controller outputs driving image data based on current frame image data supplied from an external device and the previous frame image data. Payload data are mapped onto the payload portion including plural data symbols carrying payload data of at least two mapping input data streams, the payload portion being segmented into data segments each covering a bandwidth portion of the channel bandwidth.
