Do your prints have jagged/stair stepped lines or muddy halftones? It might be caused by too low of a stencil profile. EOM is the Emulsion Over Mesh ratio that we can measure with equipment; but if you don't have these gauges, you can use your finger. You should always be able to feel an edge on the stencil.
But why is EOM important? This helpful infographic will demonstrate the print effects that stencil profiles have on print quality.

Achieving an ideal EOM is a combination of emulsion characteristics (% solids, viscosity), your mesh (thread count, tension, and % opening), your coating technique (number of passes, speed, pressure, and edge profile).
