the influence thatthe mesh count has on final printed product the need to have the correct tension on the screen the screen tension that is required on screens of various mesh counts and grades degreasing/cleaning techniques that are employed prior to coating the screen information that is contained in MSDSs for the emulsion being used the OHS requirements for exposure to UV light sources pollution and environmental issues that need to be considered when working with emulsions maintenance that is required for the automatic coating machine TWO emulsions used in screen printing and describe their characteristics, their shelf life and areas of use the storage requirements for the emulsion you are using the preparation formula for the emulsion you are using the need to have the correct illumination in the work area the influence that the length of run and ink or dye being used have on the coating technique the number of coats of emulsion and the best method of coating the screen factors that are taken into consideration in determining the angle at which the coaters coat the screen the appropriate position (horizontal or vertical) for drying the screen the effect that each of these positions has on the way the emulsion dries the effect of heat on the emulsion during the drying process the function and use of a light integrator the procedure for exposing the stencil the effect that the position, angle and distance of the light source have on the exposure process the need to have perfect contact between positive and screen during exposure the effect that temperature, pressure and time taken have on the washing out process wash-out completion the ideal position of the screen for drying to prevent scum and streaking the impact of post-curing on the stencil information that you have obtained from the MSDS for this particular blockout the bearing of ink to be used and the type of stencil on the type of blockout preventive measures that can be taken to minimise pinholes the need to tape the edge of the frame and the squeegee edge the means used to identify the screen at a later date manuals, safety and other documentation that are relevant to this task and where they are kept information that is included in these documents other sources of information that are available
