Silk mesh or Mesh:
coating-screenThere are two types of screen printing mesh material wise: one is silk mesh which is traditional and common in use for the beginners. Other is made up of polyethylene a synthetic form of silk.
There is other type mesh classification depending upon the porosity of the mesh. (numbers of holes per square unit area) most common are 100 hole mesh, 200 hole and 300 holes per square inch mesh there is another high porosity type mesh used with 355 holes per square inch.
If you have more detailed design then use some kind of thin colorant and the silk mesh should have greater number of holes per square inch and if the design is broad and ink is thick then you need a mesh with large hole size so a mesh with less numbers of holes per square inch should be used.

A Squeegee:

Make sure that the squeegee you are using has sharp ending blades this make you emulsion spread smoothly and uniformly over the mesh.
Photo-emulsion paint:
Paint made up colloidal solution of gelatin and silver halide (silver iodide, silver bromide etc.) having binder, toner and color also mixed in it. Add some amount of aqueous solution of the potassium dichromate in it as a catalyst. Before use keep the container of the photo emulsion closed.

    Procedure:

  1. Stretch the mesh on the frame at home you can do this job with hands, start from one side if you are using aluminum frame then you can you a good quality glue or nail for the wooden frame.
  2. There should be not a single one wrinkle on the stretched mesh and it should be stretched having maximum tension.
