Screen printing mesh parameters

Mesh plays the single most important role in the screen printing process, therefore a basic knowledge of different types of meshes, their technical characteristics and possible applications is essential for any screen printer. Incorrectly chosen mesh can be a source of numerous problems and frustrations both at the screen preparation stage as well as during actual printing.

The basic parameters characterizing a screen printing mesh are:

  • structure of the mesh (type of weave, type of thread)
  • material the mesh is made of (ie polyester, nylon, steel)
  • number of threads n per unit of length (n/cm or n/inch)
  • thread thickness d (μm)
  • mesh thickness D (μm)
  • open mesh area Fo (%)
  • open mesh width w (μm)
  • theoretical volume of ink transferred to the substrate Vth (cm3/m2 or in3/ft2)
  • color of the mesh

Screen printing mesh parameters

There is also a number of additional parameters such as:

  • recommended tension (N/m)
  • elongation (% or N/m)
  • modulus of elasticity (N/mm2)
  • thread thickness dispersion (±μm)
  • mesh thickness dispersion (±μm)
  • mesh opening width dispersion (±μm)


In following articles we’ll try to talk about each of those parameters and what is their practical meaning.
