what could cause the reel to wander what could cause the web to break at the unwind unit what is the difference between a "flying paster" and "zero speed" type reel-stand what print fault would result from the reel being run out of centre what possible faults in the unwind section could cause a web break what are the OHS risks associated with rewinding and sheeting what safety feature is in the delivery system if the web jams up why would the sheet cut-off wander what is the effect of poorly adjusted nip rollers when rewinding and sheeting how could a build-up of ink on the impression cylinder affect the printed product what could cause the ink to foam in the ink tray what is the effect of too much reducer in the ink what action reduces wear of the doctor blade why is it necessary that all solvents be removed from the final ink film what is the link between driers and set off and marking what could cause the substrate to distort what would be the effect in the chillers if the drying temperature was too low what is the effect of incorrect drying temperature on the finished product why is it necessary to frequently examine the in-line components of the job how is the consistency of the punching unit checked what would be the result of excessive pressure on the slitters what is the benefit of identification numbers on jobs with multiple similar images how is the ratio of print to in-line speed controlled what is the effect of inadequate communication within the work team on a gravure printing machine what safety features within the organisation aid in maintaining effective production what are the 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 what is the most accurate method of checking register during a production run why is it necessary to take immediate action when production problems are anticipated what action is taken to eliminate further processing of unacceptable printed product what will be the result to the substrate if the relative humidity is increased in the press room what is the procedure to care for a newly delivered substrate to the press room why should waste be sorted what is the advantage of keeping reusable waste what industry standards can be applied to enhance effective communication with the client what are the necessary procedures that the client should follow to "OK" a printed product when would it be necessary to call service personnel to correct a machine problem what enterprise procedures are in place to report any machine operating problems what would be the result if correct shutdown procedures were not followed why is it necessary that correct shutdown procedures are conducted with fellow workers what advantages result from proper labelling and storage of excess inks and materials why should the printed product be clearly labelled prior to removal from the press room what further operations are required for printed reels upon removal from the printing machine how should the printed job be stored after removal from the printing machine what OHS concerns should be observed when handling ink what safety precautions should be observed when cleaning the printing cylinders why is it necessary to thoroughly clean and wash up the printing unit prior to the next print run why should the doctor blades be thoroughly cleaned why should doctor blades be handled with extreme care how can printing cylinders be stored so as to minimise damage what OHS precautions should be observed when cleaning these sections of the machine why is it necessary to maintain a clean substrate handling section of the machine how are completed records used in the final analysis of the job what are the benefits of comprehensive records when considering the production of future jobs what machine manuals, safety and other documentation are relevant to this task and where are they kept and information included in these documents
