Screen printing device for applying an ink, having at least: a) a conveyor belt, b) a rotating hollow cylindrical screen stencil arranged above the conveyor belt with a circumferential screen and a rotating ink removal cylinder arranged adjacent the screen stencil, wherein: c) inside the screen stencil an ink supply device, a first doctor blade adjacent the conveyor belt, a second doctor blade adjacent the ink removal cylinder, and a third doctor blade, which is arranged upstream of the first doctor blade in the running direction of the conveyor belt and/or the rotational direction of the screen stencil are provided.

Screen printing device for applying an ink

The present invention relates to a method of manufacturing electrically conducting tracks on a transparent substrate, by screen printing with an electrically conducting paste, and to the transparent substrate provided with said tracks. According to the invention, conducting tracks are formed with a width less than or equal to 0.3 mm by applying, by screen printing, a thixotropic electrically conducting paste having a ratio of the viscosity without shear stress to the viscosity under shear stress under screen-printing conditions of at least 50 and having a silver content greater than 35% and of which at least 98% of the particles which form it have a size less than 25 &#x3bc;m, by means of a screen having at least 90 threads per cm, the coating of said screen being provided with slots, the narrowest width of which is equal to 0.25 mm&#xb1;0.05 mm, and by subjecting said tracks to baking.
