reel transportation and web control OHS concerns when operating the reel transportation system reel wander causes of web break at the unwind unit difference between a "flying paster" and "zero speed" type reel-stand print fault that would result from the reel being run out of centre faults in the unwind section that could cause a web break sheet transportation and transfer OHS concerns that are there when operating the sheet transportation system result of worn suckers at the feeder suction head type of two sheet detection on this machine movement that the sheet should have when being registered by the side lay causes of mis-register of the sheet at the feeder visible signs of the sheet being registered in the feeder gripper malfunction affecting sheet control and transfer adjustment of sheet transfer mechanisms causes of the feeder stack becoming uneven result of the feeder stack not being loaded level how unevenness of the feeder stack can be rectified reel delivery for rewinding and sheeting OHS risks associated with rewinding and sheeting what safety feature is in the delivery system if the web jams up why the sheet cut-off would wander effect of poorly adjusted nip rollers when rewinding and sheeting further operations that are required for printed reels upon removal from the printing machine how the printed job should be stored after removal from the printing machine why it is necessary to label each printed reel sheet delivery effect machine speed will have 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 that may be necessary to eliminate marking of the printed image function of a sheet decurler fitted to the delivery of some machines faults that could result from incorrectly set grippers in the transfer section of a machine how the printed job should be stored after removal from the printing machine printing unit result if the plate develops a crack at the grip edge during a print run effect of a sticky blanket surface print faults that would result from the blanket not being tensioned correctly causes of blanket packing creep during printing how a build-up of ink on the impression cylinder could affect the printed product cause of the ink to lying back in the duct causes of ink stripping on the inking rollers print faults that would result from excessive use of fountain solution on the plate recommended pH range for fountain solutions causes of the conductivity of the fountain solution to change over an eight-hour shift problems that can be caused by excessive conductivity of the fountain solutions drying unit link between driers and set off and marking what causes UV ink to dry what could cause the substrate to blister effect in the chillers if the drying temperature was too low effect of incorrect drying temperature on the finished product in-line processes consistency of the punching unit result of excessive pressure on the slitters result of a dirty former result of defective pins in the folder result of adjusting the rollers at the base of the former causes of the web jamming up in the folder maintaining production process effect of inadequate communication within the work team on a lithographic printing machine safety features within the organisation aid in maintaining effective production ramifications if machine guards are removed and/or micro switches are disconnected on a machine who would be held legally responsible for the removal of machine guards and/or disconnection of micro switches disadvantages of using a closed looped system for automatic control of the printed product other measurements besides optimum solid ink density can be measured to assess print quality most accurate method of checking register during a production run action when production problems are anticipated action to eliminate further processing of unacceptable printed product effect of relative humidity if increased in the press room procedure to care for a newly delivered skid of paper to the press room why waste should be sorted advantage of keeping reusable waste industry standards that can be applied to enhance effective communication with the client necessary procedures that the client should follow to "OK" a printed product lithographic machine operating problems when it is necessary to call service personnel to correct a machine problem enterprise procedures that are in place to report any machine operating problems correct shutdown procedures advantages that result from proper labelling and storage of excess inks and materials why the printed product be clearly labelled prior to removal from the press room cleaning and washing up the printing unit OHS concerns that should be observed when handling ink safety precautions that should be observed when cleaning the printing cylinders washing procedure for offset rubber blanket how plates can be stored 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 completing production records completed records are used in the final analysis of the job benefits of comprehensive records when considering the production of future jobs machine manuals, safety and other documentation that are relevant to this task, where kept and information that is included in these documents
