Screen printing operations are performed on uneven substrates,relying on stainless steel screen plates made with laser technology.The technical requirements of the roughness value of the wire mesh plate and the laser steel plate and the electric cast steel plate are very different,which is the different technical requirements of the roughness height of the template caused by the different application fields of the screen plate.The application of the screen is concerned with the application field and the application environment,and the principle of practicality and application should be followed.
