Version 1.0
Issue Date: April 2024


This unit requires the individual to prepare direct electronically imaged stencils.

This unit describes the performance outcomes, skills and knowledge required to prepare direct electronically imaged stencils.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 electronically imaged stencils 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 screens using direct electronic imaging 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 both of these. Off the job assessment must be undertaken in a closely replicated 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

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

OHS in relation to operating machinery such as safely switching off machinery before cleaning is started

communication of ideas and information by labelling prepared screens

collecting, analysing and organising information by drying and using emulsion according to supplier's instructions

planning and organising activities by drying the stencil prior to blocking out the screen

teamwork when maintaining the production process in association with others

mathematical ideas and techniques by correctly preparing chemicals

problem-solving skills by inspecting the stencil for flaws, scum and/orientation

use of technology by using relevant equipment to prepare direct electronically imaged stencils

Required knowledge

influence that mesh count has on final printed product

need to have a correctly tensioned screen

screen tension that is required on screens of various mesh count or grades

degreasing/cleaning techniques that are employed prior to coating the screen

information that is contained in MSDSs for the emulsion

pollution and environmental issues that need to be considered when working with emulsions

maintenance that is required on the direct projection camera

need to work in a safelight area when using the direct projection method

kinds of high sensitivity emulsion that are available and state their characteristics, lifespans and areas of use

preparation method for the emulsion you are using

influence that the length of run and ink being used have on the coating technique

number of coats of emulsion and the best method of coating the screen

best position (horizontal or vertical) for drying the screen

effect of heat on the emulsion during the drying process

OHS concerns that are there when exposing the screen

operating features of the direct projection camera

best position on the frame and the registration requirements

scanning speed and the exposure time

inputting information into the computer, manipulation of the image and output information

effect of temperature, pressure and period of washing on the emulsion

determining when washing out is complete

ideal position of the screen for drying to prevent scum and streaking

post-curing effect on the stencil

information that is obtained from the MSDSs for this particular blockout

ink to be used and the type of stencil that have a bearing on the type of blockout

what preventive measures can be taken to minimise pinholes?

need to tape the edge of the frame

means by which is this screen able to be identified at a later date

manuals, safety and other documentation that are relevant to this task and where they are kept and information that is included in these documents

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.

Coating techniques may include:

appropriate coating techniques for various emulsions, mesh types and edge definition requirements.

Type of stencil materials may include:

direct emulsion commonly used in direct projection relative to the industry sector.

Enterprise procedures may include:

tasks must be performed according to enterprise procedures.

Degree of autonomy may include:

working to defined procedures in consultation with other relevant persons to ensure production procedures are met.

Quality standards may include:

should meet client requirements and enterprise and industry standards.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
