13 Jan 2024 Stencil printing
A metal rackel is used for stencil printing. This consists of a metal blade that is supported on both sides by a guide. The paste is spread over a stencil using the squeegee. The stencil consists of a sheet of steel in which openings are lasered, which in turn represent the negative form of the printed image. The product to be printed is in direct contact underneath the stencil. If the paste is then drawn over the stencil, the paste remains in the openings on the product. The thickness of the sheet determines the layer thickness of the paste print.
