Elements and Performance Criteria

1. Select plate
   • Job specifications are interpreted to determine the appropriate type of cylinder base and/or shell for the job
   • Cylinder and/or shell is selected to deliver outputquality required by the job brief
2. Pre-plan process
   • Work area is tidied and cleaned to ensure output qualityand a safe worksite
   • Exposure and coating equipment is maintained according to manufacturer’s specifications and safety requirements
   • Exposure is controlled using step wedges and densitometry
   • Cylinder is coated according to manufacturer’s specifications
   • Cylinder is exposed making sure image direction, autotrons and tracker lines are correctly positioned according to job specifications
   • Work health and safety (WHS) requirements are observed when handling chemicals
3. Expose plate
   • Chemical balance is checked and maintained in developing tank
   • Cylinder is developed according to manufacturer’s specifications, enterprise procedures and safety requirements
4. Develop plate
   • Etching bath is maintained to correct activity level according to manufacturer’s specifications and enterprise procedures
   • Cylinder is etched according to the job specifications (cell depth)
5. Finish plate
   • Establish a chemical register to identify and describe purpose of each chemical and ensure finished cylinders meet set specifications
   • All chemicals used in the workplace are identified and registered correctly according to safe working practices

Performance Evidence

Evidence of the ability to:
