reel transportation and web control: major OHS concerns when setting up the reel transportation system causes of reel to wandering causes of the web to break at the unwind unit print faults resulting from the reel being run out of centre possible faults in the unwind section that could cause a web break sheet transportation and transfer at the feeder: major OHS concerns when setting up the sheet transportation system result of worn suckers at the feeder suction head type of two-sheet detection on the machine amount of movement the sheet should have when being registered by the side lay causes of mis-register of the sheet feeder visible signs of the sheet being registered in the feeder gripper malfunction of sheet control and transfer sheet transfer mechanisms require adjusting causes of the feeder stack to becoming uneven result of the feeder stack not being loaded level reel delivery for rewinding and sheeting OHS risks associated with rewinding and sheeting safety feature is in the delivery system if the web jams up reasons for sheet cut-off wander effect of poorly adjusted nip rollers when rewinding and sheeting sheet delivery: effect machine speed has on sheet delivery advantage of spraying moving sheets with anti set-off powder in the delivery items in the delivery that could cause marking of the printed image remedial steps necessary to eliminate marking of the printed image faults that could result from incorrectly set grippers in the transfer section of a machine devices that need to be adjusted to maintain sheet control in the delivery printing unit: result if the plate lifts at the grip edge during a print run build-up of ink on the impression cylinder affecting the printed product causes of the ink leaking back in the duct problem of paper surface picking being rectified causes of diminished impression during the print run causes of the plate surface prematurely wearing during production drying unit: eating or drinking near the machine when using UV inks link between driers and set-off and marking what causes UV ink to dry causes of the substrate blistering effect of incorrect drying temperature on the finished product in-line processes: major OHS concerns when operating cutting devices checking the consistency of the cutting and creasing unit result of excessive pressure on the slitters benefit of die cutting using a rotary die advantages of using a perforation wheel to perforate maintaining production process: affect of inadequate communication within the work team on a relief printing machine safety features within the organisation and in maintaining effective production ramifications if machine guards are removed and/or micro switches are disconnected on a machine legal responsibility for the removal of machine guards and/or disconnection of micro switches measurement other than optimum solid ink density that can be measured to assess print quality most accurate method of checking register during a production run actions to take when production problems are anticipated actions to take to eliminate further processing of unacceptable printed product affect on a stack of paper if the relative humidity is increased in the press room procedure to care for a newly delivered skid of paper to the press room reasons for sorting waste advantage of keeping reusable waste client liaison: industry standards to be applied to enhance effective communication with the client necessary procedures that the client should follow to 'OK' a printed product relief printing machine operating problems: when it is necessary to call service personnel to correct a machine problem what enterprise procedures are in place to report any machine operating problems shutdown procedures: result if correct shutdown procedures were not followed correct shutdown procedures to be conducted with fellow workers advantages that result from proper labelling and storage of excess inks and materials importance if printed product being clearly labelled prior to removal from the press room cleaning and washing up the printing unit: OHS concerns to be observed when handling ink safety precautions to be observed when cleaning the printing cylinders cleaning and washing up techniques for the printing unit prior to the next print run procedures for storing plates so as to minimise damage cleaning feed, transportation, delivery and in-line sections: OHS precautions to be observed when cleaning these sections of the machine maintaining a clean substrate handling section of the machine completing production records: completed records used in the final analysis of the job benefits of comprehensive records when considering the production of future jobs information sources: machine manuals, safety and other documentation relevant to the production of complex relief printed products other sources of available information
