A scoop coater is very simple but extremely important because it is used at the start of the screen-print process. The scoop coater is used to apply a thin layer of emulsion onto the screen. Usually, a scoop coater is metal with plastic caps to allow for ease of cleaning. The scoop coater needs to have a smooth straight edge to coat a screen evenly and smoothly. If there are any dents in the scoop coater then streakiness can occur when coating. It should always be thoroughly cleaned after use. It's also useful to have a few different sizes of scoop coaters to match your screens. The scoop coater should be roughly 3/4" thinner on each side than the mesh you are printing on. If it overlaps with the frame, then sometimes an uneven coating can occur. It's best to use a smaller one to get an even coverage of emulsion and use packing tape later on in the process to cover the edges.
