Application
This unit describes the skills and knowledge required to manually make gravure cylinders.
It requires the individual to manually make gravure cylinders by planning, selecting, exposing and developing the plate, and establishing and maintaining a chemical register.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 Select plate | 1.1 Job specifications are interpreted to determine the appropriate type of cylinder base and/or shell for the job 1.2 Cylinder and/or shell is selected to deliver output |
2 Pre-plan process | 2.1 Work area is tidied and cleaned to ensure output quality 2.2 Exposure and coating equipment is maintained according to manufacturer’s specifications and safety requirements 2.3 Exposure is controlled using step wedges and densitometry 2.4 Cylinder is coated according to manufacturer’s specifications 2.5 Cylinder is exposed making sure image direction, autotrons and tracker lines are correctly positioned according to job specifications 2.6 Work health and safety (WHS) requirements are observed when handling chemicals |
3 Expose plate | 3.1 Chemical balance is checked and maintained in developing tank 3.2 Cylinder is developed according to manufacturer’s specifications, enterprise procedures and safety requirements |
4 Develop plate | 4.1 Etching bath is maintained to correct activity level according to manufacturer’s specifications and enterprise procedures 4.2 Cylinder is etched according to the job specifications (cell depth) |
5 Finish plate | 5.1 Establish a chemical register to identify and describe purpose of each chemical and ensure finished cylinders meet set specifications 5.2 All chemicals used in the workplace are identified and registered correctly according to safe working practices |
Evidence of Performance
Evidence of the ability to:
manually produce TWO gravure cylinders and establish and maintain a chemical register according to the listed performance criteria
safely and correctly process the cylinder to ensure etching produces a quality print
find and use information relevant to the task from a variety of information sources.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
state chemical names and symbols for three chemicals used in cylinder production
describe standard safety procedures used when handling gravure chemicals
describe two methods of manual gravure cylinder production
explain cylinder balancing and how it is achieved
outline preparation processes for both steel and aluminium cylinder bases
explain Blue Print and how it is produced
outline Direct Transfer method of cylinder production
explain how cell depth is determined
identify etching solution chemical
state thickness of chrome coating on the etched surface
outline factors that govern rate of etch
list manuals, safety and other documentation relevant to this task, identify where are they kept and what information is included.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the Pre-Press field of work and include access to special purpose tools, equipment and industry software packages.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
