Application
This unit requires the individual to select computerised settings to set up and run a press to acceptable tolerances and to monitor quality both electronically and visually during the run, and to make adjustments to maintain print quality. Additional adjustments to the specifications may be made during the run and adjustments made to suit. |
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Set up print control devices | 1.1. CIP3/CIP4 data, or equivalent, is used to create a profile 1.2. Job is made ready to achieve position, register and fit to the specified standards 1.3. Colour is made ready to match appropriate colour standards 1.4. Data is interpreted and appropriate adjustments made to gain approval to run press |
2. Maintain print quality throughout the run | 2.1. Print is inspected visually to meet specified standards during run 2.2. Data is analysed against the required standards 2.3. Appropriate adjustments are made to maintain consistency throughout run 2.4. At regular intervals monitor and maintain job to ensure quality |

Evidence Required
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the ability to: may be defined by enterprise/operator or default tolerances, client requirements, colour tolerances, industry standards demonstrate an ability to find and use information relevant to the task from a variety of information sources set up and align monitoring device to appropriate standards on THREE occasions produce profiles of samples taken during THREE different print runs that show print production is within agreed tolerances, if possible using different variables evidence for assessment may be gathered from assessment of the unit of competency alone or through an integrated assessment activity. |
Context of and specific resources for assessment | Assessment must ensure: assessment may take place on the job, off the job or a combination of these. Off the job assessment must be undertaken in a closely simulated workplace environment a computerised printing machine. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: this unit is an additional skill to most printing units and may be assessed at the same time. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
