Activating chemicals are prepared according to OHS requirements and manufacturer's/supplier's specifications |
2. Prepare the screen | 2.1. Screen is selected according to job specifications 2.2. Chemicals are applied and removed according to OHS requirements and manufacturer's/supplier's specifications 2.3. Tension of screen mesh is checked for suitability according to job specifications |
3. Select indirect stencil material | 3.1. Stencil material is selected according to requirements for ink type, print resolution, substrate and machine type 3.2. Stencil material is checked for faults and expiry date and suitable action taken |
4. Process material | 4.1. Selected material is cut to size according to job specifications with minimisation of waste 4.2. Material is placed in vacuum frame with positive positioned and intimate vacuum achieved according to manufacturer's/supplier's and job specifications 4.3. Exposure is calculated and stencil is exposed according to manufacturer's/supplier's specifications 4.4. Light source is positioned according to manufacturer's/supplier's specifications 4.5. Exposed stencil is removed from vacuum frame and treated with the necessary activator, if required, according to OHS requirements and manufacturer's/supplier's specifications 4.6. Activated stencil is washed according to OHS requirements and manufacturer's/supplier's specifications 4.7. Exposed stencil is inspected for processing flaws |
5. Apply stencil to screen | 5.1. Prepared screen is re-wet and inspected for cleanliness and dust 5.2. Stencil is positioned and adhered accurately according to manufacturer's/supplier's specifications |
6. Dry stencil | 6.1. Processed stencil is dried according to manufacturer's/supplier's specifications 6.2. Backing sheet is carefully removed and stencil checked for full adhesion |
7. Block out screen | 7.1. Stencil is inspected for flaws, scum and/orientation 7.2. Non-image areas of prepared screen are blocked out with filler suitable for ink type and according to job specifications 7.3. Pinholes are spotted out with suitable filler and faulty/damaged images are retouched and are taped according to ink type and job specifications |
8. Store screen | 8.1. Prepared screen is labelled according to enterprise specifications 8.2. Prepared screen is stored in a clean, dry environment according to manufacturer's/supplier's specifications |

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 following is essential: correctly prepare direct emulsion stencils using manual techniques according to job specifications demonstrate an ability to find and use information relevant to the task from a variety of information sources prepare TWO different direct screens using manual coating and exposure techniques according to manufacturer's and job specifications, enterprise procedures and the listed Performance Criteria. |
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. |
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. |
