ABSTRACT:
In a known hot melt screen printing machine the printing ink is heated by an electrical current which is conducted through a stainless steel mesh of a screen plate. In the known machine, the printing accuracy is not good, mainly because of variation of tension and thermal expansion of the mesh.
The mesh according to the present invention consists of insulating material fibers and an electroless plating layer formed on the fibers. The plating layer preferably consists of a nickel phosphorous alloy. A squeezing means for forcing the printing ink to pass through a printing pattern and/or a printing base for mounting an article to be printed are provided with a heating means. One of the advantages of the present invention is a high printing accuracy.
