preparation of screen for coating significance of the mesh count effect that screen tension has on emulsion coating emulsion suitable for the job preparation of work area and equipment significance of good housekeeping effect that the coating trough edge have on emulsion coating selecting the right emulsions for the job choice of emulsion reasons for checking the expiry date of emulsions maximum temperature at which the emulsion can be dried coating and exposure techniques need to have good vacuum pressure in the vacuum frame why have you placed the light source in this position? formula use to calculate exposure time effects of overexposure and underexposure optimum exposure time effect on exposure that a white or coloured mesh have how do you determine if the screen is washed out properly? what characteristics determine a good or bad stencil? drying screen and blocking out drying the screen before blocking out type of filler used for blocking out reasons for spotting pinholes and taping the screen storage and OHS OHS requirements for UV exposure light means by which this screen is 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
