Silk mesh or Mesh:
There 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.

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.
